Use the following equation to answer the questions below. CH4 (g) + 2O2 (g) → CO2 (g) + 2H2O (g)

-How many moles of water are produced from the reaction of 50.0g of methane (CH4)? (Show work)

If 3 moles of a compound use 24 j of energy in a reaction, what is the a hreaction in j/mol?

What causes different colors to appear in the sky? the absorption of light by air molecules the reflection of light by bodies of water the greenhouse effect in earth's atmosphere the scattering and reflection of light by dust particles

Alice did an experiment to find the relationship between the angle at which a ray of light strikes a mirror and the angle at which the mirror reflects the light. she placed a ray box in front of a mirror. she changed the angle at which the light from the ray box struck the mirror and noted the corresponding angle at which the mirror reflected the light. which of the following is the dependent variable in this experiment? the mirror used to reflect the light the ray box used as the source of light angle at which the light from the ray box strikes the mirror angle at which the mirror reflects the light from the ray box
