In the UNBALANCED chemical reaction for the combustion of acetylene (used in welding torches), determine at standard temperature and pressure, how many liters of CO2 gas are produced if 10 liters of Oxygen gas are completely consumed? 2C2H2 + 5O2 --> 4CO2 + 2H2O
(I already balanced the equation btw)

How many moles of gas are present if p=11 atm, v=12l, t=185k?

Which of the following describes a situation where competition between producers exists

To prevent the presence of air, noble gases are placed over highly reactive chemicals to act as inert "blanketing" gases. a chemical engineer places a mixture of noble gases consisting of 4.37 g of he, 13.36 g of ne, and 36.65 g of kr in a piston-cylinder assembly at stp. calculate the partial pressure in torr of kr.
