The net ionic equation for the reaction between aqueous sulfuric acid and aqueous sodium hydroxide is a. h+ (aq) + hso4- (aq) + 2oh- (aq) → 2h2o (l) + so42- (aq) b. h+ (aq) + hso4- (aq) + 2na+ (aq) + 2oh- (aq) → 2h2o (l) + 2na+ (aq) + so42-(aq) c. so42- (aq) + 2na+ (aq) → 2na+ (aq) + so42-(aq) d. h+ (aq) + oh- (aq) → h2o( l) e.2h+ (aq) + so42- (aq) + 2na+ (aq) + 2oh- (aq) → 2h2o (l) + 2na+ (aq) + so42- (aq)

Sum of brother and sisters age is 26. four times the brothers age is subtracted from three times the sisters age, the difference is 8. what are the ages of the brother and sister?

Estimate the molar mass of the gas that effuses at 1.6 times the effusion rate of carbon dioxide.

Under what conditions will a gas be most likely to exhibit the ideal gas properties predicted by the ideal gas law? 1)high pressures and high temperature, because particles are forced closer together with higher kinetic energy, so intermolecular forces of attraction are weaker 2)high pressure and low temperature, because particles are forced closer together and moving slower, so the volume of the particles is less significant 3) low pressure and high temperature, because particles are spread farther apart and moving faster, so the intermolecular forces of attraction are weaker 4)low pressure and low temperature, because particles are spread farther apart with lower kinetic energy, so the volume of the particles is less significant
