5 Water is evaporated from the magnesium
chloride solution. The resulting solid is melted
at 700°C and decomposed by passing electric
current through it.
(a) What is the name of the physical change
that occurs first in the magnesium chloride?
(b) Write the balanced chemical equation for
this step.
(c) Identify the type of chemical reaction.
Chemical changes are caused by an input in energy. In physical changes, there is no transfer of energy.
Is the statement correct? Why or why not?
You heat 2.53 grams of metallic mercury in air, which produces 2.73 grams of red-orange residue. Assume that the chemical change is the reaction of the metal with oxygen in the air.
What is the mass of oxygen that react? When you strongly heat the red- orange residue, it decomposes to give her back the mercury and release the oxygen, which you collect. What is the mass of oxygen you collected?
