True

False

Reversible reactions proceed in Only one direction.

True

False

Irreversible reactions proceed in Only one direction.

True

False

At equilibrium,

Rate of Forward reaction = Rate of reverse reaction.

True

False

Any Reversible reaction in a CLOSED SYSTEM, will reach equilibrium eventually.

True

False

Chemical Equilibrium is DYNAMIC.

True

False

In a Reversible Reaction, if the Forward reaction is ENDOTHERMIC. Then, the REVERSE ( Backward) reaction will be .

Cannot be predicted

Exothermic

Endothermic

n2(g) + 3h2-> 2nh3(g)   this is the balanced equation

note the mole ratio between n2, h2 and nh3.   it is 1 : 3 : 2   this will be important.

moles n2 present = 28.0 g n2 x 1 mole n2/28 g = 1 mole n2 present

moles h2 present = 25.0 g h2 x 1 mole h2/2 g = 12.5 moles h2 present

based on mole ratio, n2 is limiting in this situation because there is more than enough h2 but not enough n2.

moles nh3 that can be produced = 1 mole n2 x 2 moles nh3/mole n2 = 2 moles nh3 can be produced

grams of nh3 that can be produced = 2 moles nh3 x 17 g/mole = 34 grams of nh3 can be produced

note:   the key to this problem is recognizing that n2 is limiting, and therefore limits how much nh3 can be produced.

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!

answer carbon and three oxygen atoms;
