Question

20.When black gunpowder explodes, potassium nitrate, carbon, and sulfur react with each other to form nitrogen, carbon dioxide, and potassium sulfide. If thee original mixture contains 50.0 g of potassium nitrate, what is the total volume of the gases produced in the reaction (at STP)?

Answer 1

Write the balanced chemical reaction. Then look at the mole ratios of KNO3 and the products.

Answer 2

How do i do that?

Answer 3

You are given the reactants, and products. Balance that equation.

Answer 4

Is it...KNO3+C+S--> N+CO2+KS

Answer 5

It would be 4KNO3 + 3C + S2 yields 2N2 + 3CO2 + 2K2SO3
