i need help with those question please
When Mg(ClO3)2 decomposes, the
reaction forms magnesium chloride and oxygen gas. What is the
percent yield if a chemist decomposes 25.00 g of
Mg(ClO3)2 and then isolates 8.5 g of
oxygen gas?
When an electrical current passes through water, the water
decomposes into hydrogen gas and oxygen gas. A current was passed
through 0.0155 L of water until all of it reacted. If the
scientist isolated 10.76 g of oxygen gas, what was the percent
yield? The density of water is 0.998 g/mL.
