1; the change of matter from a solid state to a gas state

2. when a is completely dissolved in a a solution is formed.

a.
solute; solvent

b.
solvent; solute

c.
dissolvent; water

d.
particle; mixture

3. used in ammonia, alka-seltzer, and dish soap

4. true or false. the mechanical advantage to simple machines is that they allow a decreased input force to create a larger output force.

5. true or false. power transfers energy into objects, while work is the rate at which energy is transferred into the object.

Nitric oxide (no) can be formed from nitrogen, hydrogen and oxygen in two steps. in the first step, nitrogen and hydrogen react to form ammonia: n2(g) + 2 h_2(g) rightarrow 2 nh_3 (g) delta h = -92. kj in the second step, ammonia and oxygen react to form nitric oxide and water: 4 nh_3(g) + 5 o_2(g) rightarrow 4no(g) + 6 h_2o(g) delta h = -905. kj calculate the net change in enthalpy for the formation of one mole of nitric oxide from nitrogen, hydrogen and oxygen from these reactions. round your answer to the nearest .

Suppose you mix one mole of sulfuric acid (h2so4) with 1 mole of sodium hydroxide(naoh). why does the ph of the solution remain below 7? ( explain so i can get better understanding! )

How do you determine the percent yield of a chemical reaction
