0. two water heaters are filled with water at 20°c. heater a holds 40.0 gallons while heater b holds
50.0 gallons. heater a is set to heat its water to a temperature of 98°c while heater b is only set at
83°c. which heater will require the most energy? show all work. (1 gallon equals 3.78 liters.) (hint:
the density of water is 1.00 kg/liter.)

Alarge marble is dropped in a graduated cylinder with 35ml of water in it.the water level increases to 49ml.what is the volume of the marble

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.

When hydrochloric acid reacts with potassium hydroxide solution, the following reaction occurs. hcl (aq) + koh (aq) h2o (l) + kcl (aq) the reaction gives off heat energy, so it is an reaction.
