According to this balanced chemical equation, what volume of C2H2 is required to form 40.0L
of CO2?

2C2H2(g) + 502(g) → 2H2O(g) + 4CO2(g)

A. 20.0L
B. 44.8L
C. 80.0L
D. 100 L

Balance this equation co2(g) + h2o (g) show that the balanced equation obeys the law if conversation of mass

Determine the wavelength of the light absorbed when an electron in a hydrogen atom makes a transition from an orbital in the n=3 level to an orbital in the n=7 level.

Consider this equilibrium: n29) + o2(g) + 2no(c).nitrogen gas and oxygen gas react when placed in a closed container. as the reaction proceeds towards equilibrium, what happens to the rate of thereverse reaction?
