3 rd period 2 electrons mean it should be Calcium
Explanation:
Answer: 10. 39.7 g
11. 650 g of
Explanation:
To calculate the moles, we use the equation:
a) moles of
According to stoichiometry :
2 moles of produce = 1 mole of
Thus 2.5 moles of produce= of
Mass of
Thus 39.7 g of will be produced from 5.0 g of hydrogen.
11.
According to stoichiometry :
1 mole of is produced by = 2 moles of
Thus 1.50 moles of are produced by = of
Mass of
Thus 650 g of woukd be decomposed to produce 1.5 mol of oxygen
