4.2 moles of CS2 contain 8,4 moles sulfur.
To find the number of moles in 19.2 g of CS2, we need to divide the given mass by the molar mass of CS2. The molar mass of CS2 is 76.14 g/mol. So, 19.2 g ÷ 76.14 g/mol ≈ 0.252 moles of CS2.
To determine the amount of CS2 that can be produced from 100 grams of S8, we need to first convert 100 grams of S8 to moles using the molar mass of S8 and then use the balanced chemical equation to find the moles of CS2 produced. Finally, we convert moles of CS2 to grams using the molar mass of CS2.

The balanced chemical equation for the reaction between carbon (C) and sulfur dioxide (SO2) is C + 2SO2 -> CS2 + 2O2. From the equation, 1 mole of C reacts with 2 moles of SO2. Therefore, you would need 0.255 moles of C to react with 0.510 moles of SO2.
4.2 moles of CS2 contain 8,4 moles sulfur.
48,5 g sample of CS2 is the equivalent of 0,637 moles.
To find the number of moles in 19.2 g of CS2, we need to divide the given mass by the molar mass of CS2. The molar mass of CS2 is 76.14 g/mol. So, 19.2 g ÷ 76.14 g/mol ≈ 0.252 moles of CS2.
6. 1 mole of CS2 contains 1 mole of carbon and 2 of sulfur.
For this you need the atomic (molecular) mass of CS2. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. CS2=76.2 grams10.00 moles CS2 × (76.2 grams) = 762 grams CS2
To determine the amount of CS2 that can be produced from 100 grams of S8, we need to first convert 100 grams of S8 to moles using the molar mass of S8 and then use the balanced chemical equation to find the moles of CS2 produced. Finally, we convert moles of CS2 to grams using the molar mass of CS2.
The balanced chemical equation for the reaction is: C + 2SO2 → CS2 + 2O2. From the equation, 1 mole of carbon produces 1 mole of CS2. Therefore, if 5.9 moles of carbon react, 5.9 moles of CS2 are produced.

The balanced chemical equation shows that 1 mole of coke reacts with 1 mole of sulfur dioxide to produce 1 mole of carbon disulfide. Therefore, if 8.0 moles of coke react, then 8.0 moles of carbon disulfide will be generated.
The balanced chemical equation for the reaction between carbon (C) and sulfur dioxide (SO2) is C + 2SO2 -> CS2 + 2O2. From the equation, 1 mole of C reacts with 2 moles of SO2. Therefore, you would need 0.255 moles of C to react with 0.510 moles of SO2.
The chemical equation for the combustion of carbon disulfide (CS2) is: CS2 + 3O2 -> CO2 + 2SO2. From the balanced equation, 2 moles of CS2 will produce 2 moles of SO2. The volume of SO2 gas formed will depend on the temperature, pressure, and volume of the reaction, as well as the ideal gas law equation (PV = nRT).
To find the heat evolved, you need to first calculate the moles of CS2 and Cl2 reacting. Then, use the stoichiometry of the reaction to determine the moles of substance reacted. Finally, use the ideal gas law to find the final volume of the gases in the reaction at the given conditions. The heat evolved can then be calculated using the heat of reaction and the moles of reactants.
