if 12.89 grams of water are produced, how many moles of C4H10 are used?

Answers

Answer 1

The mass of C4H10 that is produced is 8.4 g.

What is the number of moles used?

In this case we have to note that the stoichiometry of the reaction is very important and that is what be have to look at in the problem that we have here. For this reason, we need the reaction equation as follows;2C4H10 + 13O2 → 8CO2 + 10H2O

Then we have;

Number of moles of the water = 12.89/18 g/mol

= 0.72 moles

If 2 moles of the C4H10  produces 10 moles of water

x moles of the C4H10  produces 0.72 moles of water

x = 0.144 moles

Mass of the C4H10 = 0.144 moles * 58 g/mol

= 8.4 g

container a holds 777 ml of an ideal gas at 2.50 atm. container b holds 174 ml of a different ideal gas at 4.80 atm. container a and container b are glass spheres connnected by a tube with a stopcock. container a is larger than container b. if the gases are allowed to mix together, what is the resulting pressure?

Answers

The resulting pressure will be the average of the pressures in container A and container B.

The pressure of the resulting mixture of gases will be equal to the average of the initial pressures in container A and container B. The volume of the mixture is equal to the sum of the volumes of the two containers, so the pressure will be proportional to the number of gas particles present. To find the average pressure, we can add the initial pressures in container A and container B and divide by 2. In this case, the average pressure is (2.50 atm + 4.80 atm) / 2 = 3.65 atm.

why do we keep metal dry by heating in a test tube rater than placing the metal directly into boiling water

Answers

Keeping a metal dry during heating in a test tube provides a safer and more controlled environment for conducting reactions and analyzing the results.

When heating a metal in a test tube, it is common practice to keep the metal dry rather than placing it directly into boiling water for several reasons:

Prevention of oxidation: Keeping the metal dry during heating reduces the exposure to water and atmospheric oxygen, which can cause oxidation and corrosion of the metal.

Control of reaction conditions: Heating a dry metal in a test tube allows for better control over the temperature and reaction conditions. The temperature can be monitored and adjusted more precisely than when the metal is immersed in boiling water.

Safety: Placing a metal directly into boiling water can be dangerous, as the metal can rapidly heat up and cause the water to boil over, splashing hot liquid and steam. Heating a metal in a test tube eliminates this risk.

Avoidance of dilution: When a metal is placed directly into boiling water, it can become diluted by the water, affecting the outcome of the reaction. Heating the metal in a dry test tube eliminates this risk of dilution.

Ease of observation: When a metal is heated in a dry test tube, any changes or reactions that occur can be more easily observed and monitored, as the contents of the test tube are visible.

in a butane lighter, 9.7g of butane combine with 34.7g of oxygen to form 29.3g carbon dioxide and how many grams of water?

Answers

The equation for the combustion of butane is C4H10 + O2 --> CO2 + H2O.

What is combustion ?

Combustion is a chemical reaction between a fuel and an oxidizing agent, usually oxygen, to produce energy, usually in the form of heat and light. Combustion can be used to generate electricity, power engines, and heat homes and buildings. Combustion is also used in a wide variety of industrial processes, such as smelting, manufacturing, and food production. In combustion, the fuel is oxidized, releasing energy in the form of heat and light. This energy is usually released in the form of heat, but some fuels, such as hydrogen, can also be used to produce light. Combustion is an exothermic reaction, meaning that it releases energy in the form of heat.

When 9.7 grams of butane reacts with 34.7 grams of oxygen, 29.3 grams of carbon dioxide will be produced. In order to find the amount of water produced, we need to use the law of conservation of mass. This states that the total mass of the reactants will equal the total mass of the products.

Therefore, 9.7 grams + 34.7 grams = 29.3 grams + x, where x is the mass of water produced. Solving for x, we get x = 25.7 grams of water. Therefore, 25.7 grams of water is produced when 9.7g of butane reacts with 34.7g of oxygen.

mass, in grams, of 18.00 L of methane gas (CH4) at STP

Answers

Answer:

12.83 g.

Explanation:

At standard temperature and pressure (STP), which is defined as 0°C and 1 atm pressure, 1 mole of any gas has a volume of 22.4 liters.

Since the volume of methane gas is given as 18.00 L, we can calculate the number of moles by dividing the volume by the volume of one mole at STP:

18.00 L / 22.4 L/mol = 0.8 mol

The molar mass of CH4 is 16.04 g/mol, so we can calculate the mass of 0.8 mol of CH4 as follows:

0.8 mol * 16.04 g/mol = 12.83 g

So, the mass of 18.00 L of methane gas at STP is approximately 12.83 g.

Answers

The final number of moles of a balloon containing 0.40 moles with a volume of 5.0 is 0.08 moles.

The equation that can be used to find the final moles of gas in the balloon would be calculated as Avogadro's law.

Avogadro's law states that at constant pressure, the number of moles present in a gas is directly proportional to the volume of the gas. In other words, there is a direct relationship between the volume and the number of moles present in a gas.

The law is mathematically expressed as: v1/n1 = v2/n2

Where v1 is the initial volume of gas, v2 is the final volume, n1 is the initial number of moles, and n2 is the final number of moles of gas.

In this case, n1 = 0.40 mol, v1 = 5.0 L, and  v2= 1.0 L. What we are looking for is v1.

n2= n1v2/v1

= 0.4x1/5

= 0.08 mol

Thus, the equation to be used to find the final number of moles of the gas would be the equation derived properly from Avogadro's law.

how can a solution be hyperosmotic but hypotonic?

Answers

Answer:

Tonicity depends only on the concentration of nonpenetrating solutes, so any solution of pure glucose will be hypotonic, no matter what its osmolarity, and tonicity describes only the change in cell volume at equilibrium.

A solution can be described as hyperosmotic if it has a higher concentration of solute particles compared to another solution, while a solution is described as hypotonic if it has a lower concentration of solute particles compared to another solution.

It may seem contradictory to say that a solution can be both hyperosmotic and hypotonic, but it is possible in certain situations.

One example is when comparing a solution with a higher concentration of non-permeating solutes to a solution with a lower concentration of non-permeating solutes. Non-permeating solutes are solutes that cannot pass through the cell membrane, and therefore do not affect the concentration of solutes inside the cell.

If a solution with a higher concentration of non-permeating solutes is placed next to a solution with a lower concentration of non-permeating solutes, the first solution is hyperosmotic, but if the cell is placed in the higher concentration solution, it is hypotonic to the cell.

This is because water molecules will move from the hypotonic solution (the one with lower concentration of solutes) to the hyperosmotic solution (the one with higher concentration of solutes), causing the cell to swell and potentially burst.

if excess sulfuric acid reacts with 20 g of soidum cholride, how many grams of hytdrogen chloride are produced

Answers

According to the question, 0.343 grams of hydrogen chloride are produced.

What is hydrogen chloride?

Hydrogen chloride is a colorless, corrosive gas with a pungent odor. It is a hydrogen halide and a diatomic molecule, consisting of one atom of hydrogen and one atom of chlorine.

NaCl + H2SO4 → Na2SO4 + HCl

Since the amount of sodium chloride is given (20 g), we can calculate the amount of hydrogen chloride produced.

Since 1 mole of sodium chloride reacts with 1 mole of sulfuric acid, the number of moles of sodium chloride and sulfuric acid used in the reaction will be the same.

We can calculate the number of moles of sodium chloride used in the reaction by dividing the mass of sodium chloride (20 g) by its molar mass (58.44 g/mol).

Number of moles of sodium chloride used = 20 g / 58.44 g/mol = 0.343 moles

Since the number of moles of sodium chloride used is 0.343, the number of moles of hydrogen chloride produced will also be 0.343.

if volumes are additive and 379 ml of 0.12 m potassium bromide is mixed with 448 ml of a potassium dichromate solution to give a new solution in which [k ] is 0.713 m, what is the concentration of the potassium dichromate used to make the new solution?

Answers

The concentration of the potassium dichromate used to make the new solution is 0.0763 M.

The total volume of the new solution is 379 + 448 = 827 mL.

The total amount of potassium ions in the new solution is 0.713 * 827 = 594.491 mol.

The amount of potassium bromide in the new solution is 0.12 * 379 = 45.48 mol. The amount of potassium dichromate in the solution is 594.491 - 45.48 = 549.011 mol.

The concentration of potassium dichromate in the solution is 549.011 / 448 = 0.0763 M.

The concentration of the potassium dichromate used to make the new solution is 0.0763 M.
