Zinc reacts with hydrochloric acid according to the equation below. If 0.05 1 point mole of zinc was added to 0.075 mole of hydrochloric acid, deduce the

amount (in gram) of zinc chloride formed.

Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g)

5.11g

10.229

6.81 g

13.63 g

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:

Write 17/20 as a decimal and as a percent.

Solve for x and y: 217x + 131y = 913; 131x + 217y = 827
