Question

The equation, 2 H2(g) + O2(g) 2 H2O(l), represents an equation for a standard formation reaction.
True or False?

Answer 1

is there a reaction sign in the middle of that?

Answer 2

yea

Answer 3

between the g and the 2

Answer 4

and no It's not because it makes 2 moles of H2O for it to be standard it should make one mole

Answer 5

Sweet Thanks!

Answer 6

Can you help me with a few more t/f questions

Answer 7

Answer 8

probs

Answer 9

An exothermic reaction could be written as: heat + A + B---> AB

Answer 10

true or false?

Answer 11

nope because with an exo you get heat out so heat would be on the other side

Answer 12

If 20.6 grams of water vapor at 100 degrees Celsius completely change into a liquid at 100 degrees Celsius, the enthalpy of phase change will be negative. T/F

Answer 13

vapor to liquid. gets colder. endothermic must put heat into it so the enthalpy would be positive so false

Answer 14

One more...To calculate the change in enthalpy, it is appropriate to use the equation: ΔH = Σ Products - Σ Reactants T/F

Answer 15

truuuuuuuuuuu
