4.The heat from an acetylene torch is produced by burning acetylene (C2H2) in oxygen. 2C2H2 (g) + 5O2(g)  4CO2(g) + 2H2O (g)
How many grams of water can be produced by the reaction of 2.40 moles of C2H2 with 7.40 moles of O2?

The reaction will shift to the right

Ithe undersigned only for use your own email and delete any and copies and of the itself and to be there is a good timewhat does a decrease in temperature indicate about the molecules in a sample of liquid water? decreased chemical energy of the moleculesdecreased kinetic energy of the moleculesincreased chemical energy of the moleculesincreased kinetic energy of the moleculeshow does a sample of helium at 15 â°c compare to a sample of helium at 215 k? the helium at 15 â°c has a higher average kinetic energy than the sample at 215 k.the helium at 15 â°c has lower nuclear energy than the sample at 215 k.the helium at 15 â°c has slower-moving atoms than the sample at 215 k.the helium at 15 â°c has smaller atoms than the sample at 215 k.

C. definite shape, definite volume. that is a solid.
