Answer:
1.)calcium+hydrochloric acid -->calcium chloride +hydrogen
2.)Ca + 2HCl -->CaCl2 + H2
3.)3.55g
Explanation:
1.) pretty self explanatory
2.)Ca + HCl -->CaCl2 + H2
then balance
Ca + 2HCl -->CaCl2 + H2 (+2 infront of Hcl)
3.) take calcium and calcium chloride
Ca + CaCl2
then you need the relative atomic mass of both
Ca=40
CaCl2=71 (40+(35.5x2))
Ca=40 40/40=1 1x2=2g
Then repeat that exact equation for calcium chloride
CaCl2=71 71/40=1.775 1.775x3=3.55g
1) Number of moles of product, carbon dioxide, is the same as that of vinegar. So the most efficient reaction is the one with the less amount of baking soda. So RXN 1 is the most efficient.
2) Number of moles of product, carbon dioxide, is the same as that of vinegar; except RXN 5. There is an error in the number of moles of carbon dioxide. It should be 0.05034.
