Universal law of gravitation

 

The reaction of hydrogen with oxygen produceswater.
2H2(g)+O2(g)? 2H2O(g)

Part A: How many moles of O2are required to react with 8.0molesH2?

Part B: If you have 9.0molesO2, how many moles of H2are needed for the reaction?

Part C: How many moles of H2O form when3.5molesO2 reacts?

HW 2 Chp5 Item 9
Carbon disulfide and carbon monoxide are produced when carbon isheated iwth sulfur dioxide.
5C9s) + 2SO2(g) --> CS2(l) +4CO9g)
Part A:

Part C:
How many moles of SO2 are required to produce 0.55 mole CS2?
Part D:
How many moles of CS2 are produced when 2.3 moles C react?

HW 2 Chp5 Item 8
The reaction of hydrogen with oxygen produces water. 2H2(g) + O2(g)--> 2H2O(g)
Part A:
How many moles of O2 are required to react with 6.0 moles H2?
Part B:
If you have 7.0 moles O2, how many moles of H2 are needed for thereaction?
Part C:

HW 2 Chp5 Item 6
CO2(g) + 4H2(g) --> CH4(g) + 2H2O(g)
Part A: (express the answer with the appropriate units)
How many moles of methane are produced when 48.1 moles of carbondioxide gast reacts with excess hydgrogen gas?
Part B: (express the answer with the appropriate units)
