If you have 10 g of methane and 10 g of oxygen gas,
a) what is the most amount of WATER that could be made?
b) What is your limiting reactant in this case when you are solving for water
instead of carbon dioxide?
c) How did this example different than the last one with the multiple choice? What
do you think is the purpose of doing two that are ver similar?
Please help! I suck at chemistry!

Aglow stick contains a glass vial with chemicals. when the glow stick is bent, the vial breaks and the chemicals react to produce a glow. a science student observes that a glow stick kept in the freezer glows for a longer duration than a glow stick kept at room temperature. what conclusion can be drawn based on the observation? be sure to note the outcome and test variables in the conclusion.

Solid tin exists in two forms: white and gray. for the transformation sn(s, white) → sn(s, gray) the enthalpy change is -2.1 kj/mol and the entropy change is -7.4 j/(mol*k). a. calculate the gibbs free energy change for the conversion of 1.00 mol white tin to gray tin at -30℃. b. will white tin convert spontaneously to gray tin at -30℃? c. at what temperature are white and gray tin thermodynamically equivalent at a pressure of 1 atm?
