The amount of heat required to change liquid water to vapor at its boiling temperature is 2256 kj/kg. the amount of heat required to change liquid mercury to its vapor state at its boiling temperature is 295 kj/kg. one kg of each substance is currently at its boiling point.
how will the amount of thermal energy required to change each substance from a liquid to a gas differ?
water and mercury will require the same amount of energy to change from liquid to gas.
water will require a greater amount of energy to change from liquid to gas than mercury.
mercury will require a greater amount of energy to change from liquid to gas than water.
neither water nor mercury will require any energy to change from liquid to gas as long as they are each at their boiling temperatures.

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
