Answer:

RESHAPE BY A FORCE.

Explanation:

1. It can be reshaped by a force. Physical property can be observed and measured without any changes in molecular composition.

2. A physical property is one that can be change without altering the identity of the substance. These set of properties is not concentration dependent they are use to describe matter. Example are: density, solubility, melting point and color and odor. For this case the second option seems to fit the description it can be reshape by force.

Option A, The pH of the solution is 2.7 and the solution is acidic

Explanation:

As we know,

pH =  - log [H3O+]

Substituting the given values, we get

pH =  - log [2.1 x 10-3 M]

pH =  - (-2.678)

pH = 2.678 or 2.7

The solution is acidic as pH value is less than 7

Hence, option A is correct

Answer:

what are the options?

Explanation:

The most likely explanation for the given observations is that the crystals lose water when heated, resulting in a transition from crystals to a powdery substance and a decrease in mass after cooling. Option A

When certain substances contain water molecules as part of their crystal structure, heating them can cause the water molecules to evaporate, leading to the loss of water. This can result in a change in the physical properties of the substance, such as a transition from crystalline to powdery form.

The absence of condensation or other visible changes inside the test tube suggests that the substance is not reacting with the air or giving off a colorless gas. If such reactions were occurring, there would likely be observable changes or reactions taking place.

The decrease in mass after cooling can be attributed to the loss of water molecules. Water has mass, and when it evaporates, it escapes from the test tube, causing a reduction in the overall mass of the substance.

Option A

The ocean's surface waters typically have a pH of 8.1, making HCO3- the major carbonate species and accounting for over 90% of DIC. The second most prevalent species, CO32-, makes up around 10% of the DIC, whereas CO2(aq) makes up less than 1% of the DIC. Therefore, option D is correct.

The carbonate ion, a polyatomic ion with the formula CO23, is what distinguishes a carbonate from other salts of carbonic acid. The organic molecule with the carbonate group C(O-)2, known as a carbonate ester, may also be referred to as a carbonate.

When CO2 dissolves in water, a small quantity of carbonic acid (H2CO3) formed, but it disintegrates quickly at room temperature and pressure. Biological carbonate-containing systems and the global carbon cycle both benefit from H2CO3, despite its brief existence.

Thus, option D is correct.

The definition of molality is:

First we calculate the moles of the solute, LiCl. We do so using its molar mass:

Then we calculate the mass of the solvent, water. We do so using its density:

Finally we calculate the molality of the solution:

The correct reaction equation is; Sr(OH)2 ----> Sr + 2OH

A correct chemical reaction equation must follow the law of conservation of mass, which states that matter cannot be created or destroyed, only transformed from one form to another. This means that the total number of atoms of each element on the reactant side of the equation must be equal to the total number of atoms of each element on the product side.

To ensure that an equation is correct, you should first check that the chemical formulas of the reactants and products are correct. You can then balance the equation by adjusting the coefficients in front of each chemical formula so that the number of atoms of each element is the same on both sides of the equation.

In this question, we have a dilution situation, in which we have an initial concentration of the substance, 1.3M and an initial volume 0.40L, but after a while, we have now a volume of 0.80 L and a new concentration, we will be using the Dilution formula:

M1V1 = M2V2

We have:

M1 = 1.3 M

V1 = 0.40 L

M2 = ?

V2 = 0.80 L

Now we will add these values into the formula:

1.3 * 0.40 = 0.80 * M2

0.52 = 0.80M2

M2 = 0.65 M, this will be the new concentration of the substance after adding more water

The moles of Cl₂(g) will be present at equilibrium is 3.94 × 10⁻⁴ mol

To determine the number of moles of Cl₂(g) at equilibrium, we need to use the given equilibrium constant (Kₑ) and the initial concentrations of CO(g) and COCl₂(g).

Given:

[CO(g)] = 0.3500 mol

[COCl₂(g)] = 0.05500 mol

Kₑ = 1.2 × 10²

The balanced equation for the reaction is:

CO(g) + Cl₂(g) ⇌ COCl₂(g)

Let's denote the number of moles of Cl₂(g) at equilibrium as x. At the start, we have [Cl₂(g)] = 0 mol, but it will change by x at equilibrium.

Using the equilibrium expression, we can write:

Kₑ = [COCl₂(g)] / ([CO(g)] * [Cl₂(g)])

Plugging in the values:

1.2 × 10² = [COCl₂(g)] / (0.3500 * [Cl₂(g)])

To solve for [Cl₂(g)], we need to isolate it on one side of the equation:

[Cl₂(g)] = [COCl₂(g)] / (0.3500 * Kₑ)

Now, let's substitute the given values:

[Cl₂(g)] = 0.05500 / (0.3500 * 1.2 × 10²)

[Cl₂(g)] ≈ 3.94 × 10⁻⁴ mol

Therefore, approximately 3.94 × 10⁻⁴ moles of Cl₂(g) will be present at equilibrium.

Starting with 0.3500 mol CO(g) and 0.05500 mol COCl₂(g) in a 3.050-L flask at 668 K, how many moles of Cl₂(g) will be present at equilibrium

CO(g) + Cl₂(g) ⇄ COCl₂(g)  Ke 1.2 x 10^{2} at 668 K

The equilibrium constant for the system at this temperature is\(1.17 × 10^-31 mol^2/L^2\).

For the chemical equation:

N2(g) + O2(g) ⇌ 2NO(g)

The equilibrium mixture at a temperature of 1500 K is determined to contain 6.4 × 10^-3 mol/L of N2,\(1.7 × 10^-3\)mol/L of O2 and 1.1 × 10^-5 mol/L of NO.  First, we need to calculate the concentration of N2 and O2 required to produce

1.1 × 10^-5 mol/L of NO:

2NO(g) = N2(g) + O2(g)

Given that there are 1.1 × 10^-5 mol/L of NO, the number of moles of N2 and O2 are equal since the stoichiometric ratio is 1:1. Therefore:

\(1.1 × 10^-5 mol/L\) = [N2][O2]Kc = \(([NO]^2)/([N2][O2])Kc\)= \((1.1 × 10^-5 mol/L)^2/(6.4 × 10^-3 mol/L)(1.7 × 10^-3 mol/L)Kc\) =

The value of ΔG at 25 °C for the given reaction is: ΔG = -370.4 kJ/mol + 0 = -370.4 kJ/mol So, the correct answer is -370.4 kJ/mol

To determine the value of ΔG (Gibbs free energy) at 25 °C for the given reaction:

25 (s, rhombic) + 3/2 \(O_2\)(g) → \(2SO_3\)(g)

We can use the equation:

ΔG = ΔG° + RT ln(Q)

where:

ΔG is the standard Gibbs free energy change

ΔG° is the standard Gibbs free energy change under standard conditions

R is the gas constant (8.314 J/(mol·K) or 0.008314 kJ/(mol·K))

T is the temperature in Kelvin (25 °C = 298 K)

Q is the reaction quotient, which is the ratio of the concentrations of the products to the concentrations of the reactants at a given point during the reaction.

Given that ΔG° is -370.4 kJ/mol, we can plug the values into the equation:

ΔG = -370.4 kJ/mol + (0.008314 kJ/(mol·K) * 298 K) * ln(Q)

Now, we need to determine the value of Q. Since all reactants and products are in their standard states, Q = 1, as their concentrations are taken to be 1.

ΔG = -370.4 kJ/mol + (0.008314 kJ/(mol·K) * 298 K) * ln(1)

Since ln(1) = 0, the term (0.008314 kJ/(mol·K) * 298 K) * ln(1) becomes 0.

Therefore, the value of ΔG at 25 °C for the given reaction is:

ΔG = -370.4 kJ/mol + 0 = -370.4 kJ/mol

So, the correct answer is -370.4 kJ/mol.

This is true because in many storms, there are very high wind speeds.

This is an ideal gas problem, so let's see the relationships of volume with pressure and temperature:

The concentration (in mole/liter) of the nitric acid is 0.139 M.

Concentration refers to the amount of a substance in a defined space. Another definition is that concentration is the ratio of solute in a solution to either solvent or total solution.

There are various methods of expressing the concentration of a solution.

Concentrations are usually expressed in terms of molarity, defined as the number of moles of solute in 1 L of solution.

Solutions of known concentration can be prepared either by dissolving a known mass of solute in a solvent and diluting to a desired final volume or by diluting the appropriate volume of a more concentrated solution (a stock solution) to the desired final volume.

Given,

Volume of NaOH = 11.02 ml

Concentration of NaOH = 0.253 M

Volume of nitric acid = 20.05 ml

Number of moles stay same on neutralisation, so

Volume of NaOH × Concentration of NaOH = Volume of nitric acid × concentration of nitric acid.

11.02 × 0.253 = 20.05 × concentration

Concentration of nitric acid = 0.139 M
