Based on the mass ratio of reactants, 23.5 g of sodium nitrate is produced from the reactants.

The mass ratio of a reaction is the ratio of the masses of reactants wilhich combine to form products.

The mass of sodium nitrate is determined from the mass ratio.

The equation of the reaction gives the mass ratio as follows:

NaCl + AgNO3 ----> AgCl + NaNO3

Molar mass of NaCl = 58.5 g

Molar mass of AgNO3 = 170 g

Molar mass of AgCl = 143.5

Molar mass of NaNO3 = 85 g

There are 98 grams of sodium chloride, 47 grams of silver nitrate, therefore silver nitrate is the limiting reactant.

47 grams of silver nitrate will produce 85/170 × 47 = 23.5 g of sodium nitrate.

Therefore, 23.5 g of sodium nitrate is produced from the reactants.

Explanation:

Draw a structural formula for the major product of the reaction shown:

The structural formula for the major product (2-butene) of the given reaction is as follows:$$\ce{CH3CH2CH=CH2}$$

The given reaction is an acid-catalyzed dehydration reaction.

During the reaction, the hydroxyl group (OH) and the adjacent hydrogen atoms (H) on the reactant alcohol (2-butanol) undergo dehydration (loss of water) to form an alkene (2-butene) as the major product.

The reaction is shown below:$$\ce{CH3CH2CH2CH2OH + H2SO4 ->[\Delta] CH3CH2CH=CH2 + H2O}$$To draw the structural formula for the major product of the given reaction, we need to consider the following points:

1. The reactant alcohol (2-butanol) is a four-carbon alcohol with the hydroxyl group (OH) attached to the second carbon atom (C2) of the chain.

2. The product alkene (2-butene) will be a four-carbon alkene with a double bond between the second and third carbon atoms (C2 and C3) of the chain.

The other two carbon atoms will have a single bond with the adjacent carbon atoms and a hydrogen atom each attached to them.

3. The major product will be formed via the elimination of water (dehydration) between the hydroxyl group (OH) and the adjacent hydrogen atoms (H) on the second carbon atom (C2) of the reactant alcohol (2-butanol).

4. The acid catalyst (H2SO4) does not participate in the reaction and remains unchanged. It only facilitates the formation of the alkene by providing a proton (H+) to the hydroxyl group (OH) and a medium for the elimination of water.

The products formed in the acid-base reaction between NaOH and HCl are NaCl (sodium chloride) and H₂O (water).

NaOH + HCl → NaCl + H₂O

In this reaction, NaOH is a strong base, and HCl is a strong acid. A strong base is one that completely dissociates in water to form hydroxide ions (OH⁻) while a strong acid is one that completely dissociates in water to form hydrogen ions (H⁺).

NaOH + H₂O → Na⁺ + OH⁻

HCl + H₂O → H⁺ + Cl⁻

When NaOH is added to HCl, the hydroxide ions (OH⁻) from the NaOH react with the hydrogen ions (H⁺) from the HCl to form water (H2O). The remaining ions, Na⁺ and Cl⁻, combine to form sodium chloride (NaCl), which is a salt.

Na⁺ + Cl⁻ → NaCl

The reactants in this reaction are a strong base (NaOH) and a strong acid (HCl), and the products are a salt (NaCl) and water (H₂O). This reaction is an example of neutralization, which is a reaction between an acid and a base that produces a salt and water. The Na⁺ ion is the conjugate acid of the strong base NaOH, while the Cl⁻ ion is the conjugate base of the strong acid HCl

Answer:

limiting reagent is 02

mass of CO2 is 11g

Explanation:

the limiting reagent is the reagent which is consumed completely

no of mole of CH2 = m in g / molar mass

= 46.0/(12+2)

= 3.285 moles.

no of mole of O2 = 32/32

= 1 mole

from the reaction

1 mole of CH2 ==> 2 mol of O2

3.285 mol ==> 1/2 mol

3.285 mol ==> 0.5 mol

:. since O2 has the lowest mol , it's the limiting reagent

the limiting reagent mol will be used to find the no of mole of CH2

2 mol of O2==> 1 mol of CO2

0.5 mol ==> 0.5/2

0.25 mole of CO2

mass = 0.25 * ( 12+32)

Answer:

48.4%

Explanation:

Mass percent is calculated by the equation:

mass of element / total mass * 100%

Plugging in the figures of the problem: 242g / 500g * 100% = 48.4% (grams are in the numerator and denominator, so they cancel out)

The mass percent of iron in the ore sample is 48.4 %.

The percentage of an element in a compound can be described as the number of parts by mass of that element present in 100 parts by mass of that compound.

The mass percentage of an element can be evaluated in two steps: First, determine the molecular mass of the given compound by the addition of the atomic masses of the elements. Then, the percentage of the elements can be determined by dividing the total mass of the element present in that compound by the molar mass of the given compound multiplied by 100.

Given, the mass of the iron in sample = 242 g

The total mass of the iron ore sample = 500 g

The mass percentage of the iron = (242/500) × 100 = 48.4 %

Therefore, the mass percentage of the iron in the iron ore sample is equal to 48.4%.

Answer: :)

The temperature of a gas is directly proportional to the average kinetic energy of the particles of the gas. But the total kinetic energy of the molecules of a gas is a measure of the internal energy or thermal energy of the gas.

Explanation:

The first equation is a balanced chemical equation because the number of atoms of each element on the left side of the equation is equal to the number of atoms of each element on the right side of the equation.

2HCl(aq) + Ca(OH)₂(aq) → CaCl₂(aq) + 2H₂O(l)

A balanced chemical equation is an equation that has the same number of atoms for each element on both sides of the equation. For example, the balanced chemical equation for photosynthesis is 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂. This equation shows that the number of atoms of each element on the left side is equal to the number of atoms of the same element on the right side.

An atom is the smallest unit of matter that makes up all physical substances. It is composed of three smaller particles – protons, neutrons, and electrons. Protons have a positive charge and neutrons have no charge, while electrons have a negative charge. Protons and neutrons make up the nucleus of an atom, located at its center, while electrons orbit around it. Atoms of the same element all have the same number of protons, but they can differ in the number of neutrons and electrons.

Mass percentage does not have any unit as numerator and denominator contains the same unit. Therefore, percentage of mass of sulfur is 20%.

Mass percentage represents the the percentage of each element that is making a particular compound.

Mathematically,

Percentage of mass = (component’s mass ÷ total mass) x 100%

mass of sulfur=32.07 g/mol

mass of CuSO₄= mass of copper +mass of sulfur+4×mass of oxygen

                         =63.55 g/mol+32.07 g/mol+4×16.00 g/mol

                         =160g/mol

Percentage of mass of sulfur = (32.07 g/mol÷ 160g/mol) x 100%

Percentage of mass of sulfur =20%

Mass is the independent variable, and boiling point is the dependent variable.

The formula for calculating the amount of energy or heat released is:

ΔH = C ΔT

where ΔH is heat of combustion, C is heat capacity, while ΔT is change in temperature

ΔH = 8.69 kJ / °C * (5.14°C)

ΔH = 44.67 kJ

Then we calculate the moles of CH3OH which has molar mass of 32.04 g/mol:

moles = 1.922 / 32.04 = 0.05999 mol

SO the molar heat of combustion is:

ΔHm = 44.67 kJ / 0.0599875 mol

ΔHm = 744.60 kJ / mol

V = πr²h

where r is the cylinder's radius, h is its height, and is the mathematical constant pi (approximately equal to 3.14159).

We must first determine the cylinder's radius in order to compute the volume of the cylinder with a height of 11.76 cm and a diameter of 7.22 cm:

r = d/2 = 7.22 cm / 2 = 3.61 cm
