Answer:

5. The mass of Na₂CO₃, that will produce 5 g of CO₂ is approximately 12.04 grams of Na₂CO₃

6. The mass of nitrogen gas (N₂) that will react completely with 150 g of hydrogen (H₂) in the production of NH₃ is 693.[tex]\overline{3168}[/tex] grams of N₂

Explanation:

5. The given equation for the formation of carbon dioxide (CO₂) from sodium bicarbonate (Na₂CO₃)  is presented as follows;

(Na₂CO₃) + 2HCl → 2NaCl + CO₂ + H₂O

One mole (105.99 g) of Na₂CO₃ produces 1 mole (44.01 g) of CO₂

The mass, 'x' g of Na₂CO₃, that will produce 5 g of CO₂ is given by the law of definite proportions as follows;

[tex]\dfrac{x \ g}{105.99 \ g} = \dfrac{5 \ g}{44.01 \ g}[/tex]

[tex]\therefore {x \ g} = \dfrac{5 \ g}{44.01 \ g} \times 105.99 \ g \approx 12.04 \ g[/tex]

The mass of Na₂CO₃, that will produce 5 g of CO₂, x ≈ 12.04 g

6. The chemical equation for the reaction is presented as follows;

N₂ + 3H₂ → 2NH₃

Therefore, one mole (28.01 g) of nitrogen gas, (N₂), reacts with three moles (3 × 2.02 g) of hydrogen gas (H₂) to produce 2 moles of ammonia (NH₃)

The mass 'x' grams of nitrogen gas (N₂) that will react completely with150 g of hydrogen (H₂) in the production of NH₃ is given as follows;

[tex]\dfrac{x \ g}{28 .01 \ g} = \dfrac{150 \ g}{3 \times 2.02 \ g} = \dfrac{150 \ g}{6.06 \ g}[/tex]

[tex]\therefore \ x \ g= \dfrac{150 \ g}{6.06 \ g} \times 28.01 \ g = 693.\overline {3168} \ g[/tex]

The mass of nitrogen gas (N₂) that will react completely with 150 g of hydrogen (H₂) in the production of NH₃, x = 693.[tex]\overline{3168}[/tex] grams

Answers

Answer:

A. 650 g

Explanation:

The equation of the reaction is given as;

2 HgO(s) --> 2Hg(s)  + O2(l)

From the reaction;

2 mol of HgO produces 1 mol of O2

x mol of HgO would produce 1.50 mol of O2

2 = 1

x = 1.5

Solving for x;

x = 1.5 * 2 / 1 = 3 mol

Converting to mass;

Mass = Number of moles * Molar mass

Mass = 3 mol  * 216.59 g/mol

Mass = 649.77 g ≈ 650. g

Answer:

some animals exhibit structures that are no longer used for any purpose

Explanation:

Vestigial structures are defined as the the organs which are no longer used for any purpose.

Vestigial structures provide evidences of common ancestors as they shows how organisms changed or evolved in the use of these structures. for example: human appendix which is no longer functional in human body but as per Darwin's theory of evolution it was once used by our herbivorous ancestors to protect good bacteria in the gut.

For the reaction between aqueous silver nitrate and aqueous sodium chloride, write each of the following. The products of the reaction are aqueous sodium nitrate and solid silver chloride.
Complete equation
Complete ionic equation
Net ionic equation

Answers

Answer:

A balanced ionic equation shows the reacting ions in a chemical reaction. These equations can be used to represent what happens in precipitation reactions or displacement reactions.

Precipitation reactions

In a typical precipitation reaction, two soluble reactants form an insoluble product and a soluble product.

For example, silver nitrate solution reacts with sodium chloride solution. Insoluble solid silver chloride and sodium nitrate solution form:

AgNO3(aq) + NaCl(aq) → AgCl(s) + NaNO3(aq)

The Na+ ions and NO3- ions remain separate in the sodium nitrate solution and do not form a precipitate. Ions that remain essentially unchanged during a reaction are called spectator ions.This means these can be ignored when writing the ionic equation. Only how the solid silver chloride forms is needed to be shown:

Ag+(aq) + Cl-(aq) → AgCl(s)

In a balanced ionic equation:

the number of positive and negative charges is the same

the numbers of atoms of each element on the left and right are the same

Displacement reactions

Displacement reactions take place when a reactive element displaces a less reactive element from one of its compounds.

A common type of displacement reaction takes place when a reactive metal reacts with the salt of a less reactive metal. For example, copper reacts with silver nitrate solution to produce silver and copper(II) nitrate solution:

2AgNO3(aq) + Cu(s) → 2Ag(s) + Cu(NO3)2(aq)

In this reaction, the NO3- ions remain in the solution and do not react - they are the spectator ions in this reaction. So, they can be removed from the ionic equation:

2Ag+(aq) + Cu(s) → 2Ag(s) + Cu2+(aq)

Question

Explain why this ionic equation is balanced:

Ba2+(aq) + SO42-(aq) → BaSO4(s)

Hide answer

There are the same numbers of atoms of each element on both sides of the equation. The total charge on both sides is also the same (zero).

Question

Balance this ionic equation, which represents the formation of a silver carbonate precipitate:

Ag+(aq) + CO32-(aq) → Ag2CO3(s)

Hide answer

Question

Balance this ionic equation, which represents the displacement of iodine from iodide ions by chlorine:

Cl2(aq) + I-(aq) → I2(aq) + Cl-(aq)

Explanation:

When 10 grams of water completely evaporate into water vapor, the volume of the water vapor is greater than the volume of the original liquid water, but the mass remains the same. Why does the mass stay the same? Which answer is correct?

A
The temperature of the liquid water and water vapor is the same.

The temperature of the liquid water and water vapor is the same.

B
The density of the liquid water is the same as the density of the water vapor.

The density of the liquid water is the same as the density of the water vapor.

C
The number of atoms in the water vapor is equal to the number of atoms in the liquid water.

The number of atoms in the water vapor is equal to the number of atoms in the liquid water.

D
The distance between the water molecules is the same in the liquid and the vapor.

The distance between the water molecules is the same in the liquid and the vapor.

Answers

Answer: I think the answer is B or C, its kind of hard.

As the number of atoms in the water vapor is equal to the number of atoms in the liquid water. Therefore, the mass of the water remains the same.

What is evaporation?

Evaporation is a process that usually happens on the surface of water or liquid and it involves the conversion of the liquid phase into the gaseous phase. This process involves a change in the state of matter of water or liquids.

When the water is completely evaporated into water vapor the density of the water vapor is less than the density of the liquid water as the vapors occupy a large volume in comparison to liquid water.

But the number of atoms in the water vapor is the same as the number of atoms in the liquid water. The mass of the water is due to the mass of the atoms.

Therefore, the mass of the water remains the same during the phase transition from liquid water to water vapors. Therefore, option (C) is correct.
