Answer:
Truck B will have a greater stopping distance.
Explanation:
I did it before
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
Ooo that cool good thing I learn from this app
