As that liquid water is further heated, it evaporates and becomes a gas—water vapor.

When a liquid transitions from the liquid phase to the gas phase, evaporation, a sort of vaporization, takes place on the liquid's surface. High concentrations of the evaporating substance in the surrounding gas considerably slow down evaporation, as is the case when humidity impacts the rate of water evaporation.

The way that the liquid's molecules clash determines how much energy is transferred to one another. In order to leave and enter the surrounding air as a gas, a molecule close to the surface must absorb enough energy to outperform the vapor pressure. Evaporative cooling is the process of reducing a liquid's temperature as a result of evaporation, which removes energy from the evaporated liquid.

The majority of the liquid's molecules only hold a small portion of the heat energy needed.

The volume occupied by one mole of gas at stp is known as the standard molar volume of a gas. It has been found to be 22.41410 L. According to Avagadro's law, one mole of any gas will occupy the same volume as one mole of any other gas at the same temperature and pressure, despite mass difference. Knowing the volume of gas, you can use 1 mol/22.4L as a conversion factor to find the number of moles, and therefore the mass, of a given volume of a given gas at STP.

These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. Different isotopes of the same element have different masses. Mass is the word for how much substance (or matter) something has.

In forming the Al³⁺ ion, the Al atom loses the electrons in its outermost energy level, causing a decrease in the atomic radius, hence option A is correct.

The number of protons in the nucleus of AlandAl3+ AlandAl3+ is the same, however there are differing numbers of electrons in the final shell. Al³⁺ is smaller than Al because it has fewer electrons.

The Al atom will become an Al³⁺ ion when it loses its third electron and develops a tri-positive charge on it. In forming the Al³⁺ ion, the Al atom loses the electrons in its outermost energy level, causing a decrease in the atomic radius.

Explanation:

atoms in a metallic solid loose their outer electrons and form a regular lattice of positive metallic ions.

The chemical bondings are present between the atoms due to the attractive forces. The bond shown in the diagram represents the metallic bonds. Thus, option A is correct.

A metallic bond is a chemical bonding present due to the electrostatic attractive forces present between the delocalized electrons and the ions of the metals.

The metal produces cations that bond with the electrons delocalized around them. This type of bonding accounts for the malleability and conductivity of the metallic species.

The delocalized electrons are shared by the positively charged metal ions. The cations are largely spread in space. It is seen in the elements of aluminum, magnesium, copper, sodium, zinc, calcium, etc.

0.297 kJ of heat is needed to raise the temperature of 10g of aluminum from 22 degrees Celsius to 55 degrees Celsius.

The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius.

It is a measure of how much energy it takes to raise the temperature of a substance. It is the amount of heat necessary to raise one mass unit of that substance by one temperature unit.

It is given by the formula -

                                                  Q = mcΔT

where, Q = amount of heat

m = mass

c = specific heat

ΔT = Change in temperature

Given,

mass = 10g

c = 0.901J/g⁰C

Initial temperature (T₁) = 22⁰C

Final Temperature (T₂) = 55⁰C

Q = mcΔT

= 10 × 0.901 × (55 -22)

The strand 1 of hydrocarbons is used to produce plastic, hence option D is correct.

Raw resources like natural gas, oil, or plants that have been processed into ethane and propane are used to make plastics. The subsequent "cracking" procedure uses heat to transform ethane and propane into ethylene and propylene. To produce various polymers, these components are mixed.

Propylene is a substance found in large quantities in petroleum. In order to speed up chemical processes, refiners combine heated propylene with a catalyst to create plastic. Propylene molecules start to cluster together like beads on a thread as a result.

(a) the molecular formula of the compound is C₆H₁₂.

(b)  the molecular formula of the compound is NH₂Cl.

(a) Given the empirical formula CH₂ and a molar mass of 84 g/mol, we need to determine the molecular formula. To do so, we need to find the factor by which the empirical formula needs to be multiplied to achieve the given molar mass.

The empirical formula CH₂ has a molar mass of 14 g/mol (12 g/mol for carbon + 2 g/mol for hydrogen).

To find the factor, we divide the molar mass by the empirical formula mass:

Factor = (molar mass) / (empirical formula mass) = 84 g/mol / 14 g/mol = 6

Therefore, the molecular formula is obtained by multiplying the empirical formula by the factor:

CH₂ × 6 = C₆H₁₂

Thus, the molecular formula of the compound is C₆H₁₂.

(b) Given the empirical formula NH₂Cl and a molar mass of 51.5 g/mol, we follow a similar approach.

The empirical formula NH₂Cl has a molar mass of 51.5 g/mol (14 g/mol for nitrogen + 2 g/mol for each hydrogen + 35.5 g/mol for chlorine).

To find the factor, we divide the molar mass by the empirical formula mass:

Factor = (molar mass) / (empirical formula mass) = 51.5 g/mol / 51.5 g/mol = 1

Therefore, the molecular formula is the same as the empirical formula: NH₂Cl

Hence, the molecular formula of the compound is NH₂Cl.

b) The temperature of the water goes up

c) The piston move in

d) Work is done on the gas mixture

e) The amount of work done on the gas mixture is given as

W = PΔV

where

W is the work done on the gas mixture

P is the pressure within the cylinder after the reaction

ΔV is the change (a decrease) in volume of the gas mixture

Explanation:

a) Since the chemical reaction is known to release energy into the surrounding, then it is an exothermic reaction.

b) Sine the reaction releases energy into the water, the energy of the water will go up, causing the temperature of the water to go up.

c) The piston will move in, since it was determined from data that the piston does work on the system. When the piston moves in work is done on the system.

d) Work is done on the gas mixture, because the piston moves in, compressing the gas.

e) From basic thermodynamics, we know that when work is done a system, then it means the system is compressed, and the equation for the work done on a system is given as

W = PΔV

where

P is the pressure withing the cylinder

ΔV is the change in the volume of the system. The volume of the system decreases, and hence the work done will be negative.

The concentration of Ca²⁺ at equilibrium at 25°C is 5.79 × 10⁻¹² M.

In chemistry, the abundance of constituent divided by the total volume of a mixture is called concentration.

CaCO₃(s) + 2H+ → CO₂(g) + H₂O(l) + Ca₂+(aq)

K_eq = [Ca²⁺][CO₂]/([H+]²)

Given: [H+] = 10⁻⁷ M and PCO2 = 10^-3.5 atm,

[CO₂] = PCO₂/KH, KH is the Henry's law constant for CO₂ in water.

At 25°C,  value of KH is approximately 3.4 × 10⁻² mol/L*atm, so:

[CO2] = 10^-3.5 atm / (3.4 × 10⁻² mol/L*atm) = 2.94 × 10⁻² M

6.2 × 10⁹ = [Ca²⁺](2.94 × 10⁻²) / (10⁻⁷)²

[Ca²⁺] = K_eq [H+]² / [CO2] = 6.2 × 10⁹ × (10⁻⁷)² / (2.94 × 10⁻²) = 5.79 × 10⁻¹² M

Explanation:

both rust and bubbles are products of chemical change whilst freezing ad dissolving are physical.

The first change is a chemical change, the second and the third change is a physical change, and the fourth change is a chemical change.

While a physical change does not result in a new substance, a chemical change does. While experiencing a physical change, a material may change shape or form, but no chemical processes take place, and no new compounds are created. Other signs of chemical and physical alterations also exist.

A chemical change happens when the atoms reorganize themselves to establish new chemical bonds, creating a new molecule (product). Chemical reactions are always a part of chemical changes. The initial components and the finished result differ chemically from one another.

In a physical transformation, no new chemical species is created. Since the identity of the matter does not change, changing a pure substance's state from solid to liquid or gas constitutes a physical change. A physical alteration affects just physical attributes; chemical properties are unaffected. For instance, crystallization, melting, and steel tempering all affect the physical characteristics of materials.

Therefore, the first and fourth is a chemical change and the second and third is a physical changes.

The piece of evidence that best identifies the type of reaction as nuclear or chemical is: Chemical, because a new substance is formed. Option 4

In this scenario, the observation that a new substance is formed is a key characteristic of a chemical reaction. Chemical reactions involve the rearrangement of atoms to form different substances with distinct properties. The formation of a new substance indicates a chemical change has occurred.

The other pieces of evidence listed do not necessarily point to a nuclear reaction:

Chemical, because energy is released during the reaction: Energy can be released in both nuclear and chemical reactions, so this observation alone is not sufficient to determine the type of reaction.

Nuclear, because energy is released during the reaction: While energy can be released in nuclear reactions, it is not exclusive to them. Chemical reactions can also release energy, such as in exothermic reactions.

Nuclear, because the mass decreased after the reaction: This observation suggests a change in mass, which could be indicative of a nuclear reaction. However, it is important to consider that chemical reactions can also involve changes in mass, such as the formation of gases or dissolution of a solid.

Overall, the most conclusive evidence to identify the type of reaction is the formation of a new substance, which aligns with a chemical reaction.

The partial pressure of nitrogen on Venus is approximately 321.914 kPa.

To find the partial pressure of nitrogen on Venus, we need to calculate the partial pressure using the mole fraction of nitrogen and the total atmospheric pressure. First, we convert the total atmospheric pressure from psi to kilopascals (kPa) since the mole fraction is given in terms of kPa.

1 psi = 6.89476 kPa

Therefore, the total atmospheric pressure on Venus is:

1334 psi × 6.89476 kPa/psi = 9197.53 kPa

Next, we can calculate the partial pressure of nitrogen using the mole fraction. The mole fraction of nitrogen is given as 0.035, which means that nitrogen makes up 3.5% of the total moles of gas in the atmosphere.

The partial pressure of nitrogen is given by:

Partial pressure of nitrogen = Mole fraction of nitrogen × Total atmospheric pressure

Partial pressure of nitrogen = 0.035 × 9197.53 kPa

Partial pressure of nitrogen = 321.914 kPa

Therefore, the partial pressure of nitrogen on Venus is approximately 321.914 kPa.
