Answer:
.6250 M
The Sodium Hydroxide is the solute, and the water is the solvent.
Explanation:
mol/volume= Molarity
(25/22.99+16+1.008)/1=.6250 M.
The frozen balloon shrank because the average kinetic energy of the gas molecules in a balloon decreases when the temperature decreases. This makes the molecules move more slowly and have less frequent and weaker collisions with the inside wall of the balloon, which causes the balloon to shrink a little.
Answer:
a) molarity of CCl3F = 1.12 × 10^-11 mol/dm³
Molarity of CCl2F2 = 2.20 × 10^-11 mol/dm³
B) molarity of CCL3F = 7.96 × 10 ^-13 mol/dm³
Molarity of CCl2F2 = 1.55 × 10^-12 mol/dm³
Explanation:
Using the ideal gas equation:
PV = nRT

N2 + 3 H2 -> 2 NH3
<span>Just use their stoichiometric coefficients (number before the chemical's name) from the balanced chemical reaction to make ratios and solve for the unknown. In this case, 2 moles of NH3 are produced for every 3 moles of H2. Thus, </span>
<span>7.5 moles H2 x (2 moles NH3 / 3 moles H2) = 5 moles NH3
