When burning methane gas, which outcome best demonstrates the law of conservation of mass? a. ch4 → co2 + h20 b. ch4 + o2→ co2 + 2h20 c. ch4 + o2 → 2co2 + 2h20 d. ch4 + 2o2 → co2 + 2h20

Answer  Option D

Counting the  number of atoms each side of the equation shows that the numbers balance.

lol for the pointsss

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42

2.4
