Answer: The pH of the solution will decrease by 1 unit.
Explanation:
Let say the hydronium ion concentration of a solution is 0.001
pH = - log [H+]
= -log 1.0 x 10^3 = 3
if the hydronium ion concentration is increased by 10 , that is: 0.001 x 10 = 0.01
pH = -log [1.0 x 10^2]
= 2
Therefore, the pH is reduced by 1 unit when the hydronium ion concentration is increased by a factor of 10.
D.
The water must be heated and removed in distillation, so thermal energy is required.
Answer:
They form crystals, they have really high boiling points, They have higher enthalpies of fusion and vaporize than an molecular compound, the are brittle

Answer:
148.2 g of H20
Explanation:
Equation of reaction: 4NH3 + 5O2 ---> 4NO + 6H20
From the equation above, 4 moles of ammonia reacts with 5 moles of oxygen gas to produce 6 moles water.
Molar mass of NH3 = 17 g/mol;
Molar mass of O2= 32 g/mol;
Molar mass of H2O = 18 g/mol
First, we determine the limiting reactant:
4*17 g of NH3 reacts with 5*32 g of O2
Mass Ratio = 68 : 160
Therefore, NH3 is the limiting reactant.
68 g of NH3 reacts to produce 6* 18 g of H20 = 108 g of H2O
93.3 g of NH3 will react to produce (93.3 * 108)/68 g of H20 = 148.2 g of H2O
Therefore, the maximum amount of H2O produced = 148.2 g
