Answer:9.82 m

Explanation:

As we know from equation of motion

S=v*t +0.5 a t^2

Know s=H/2

a =9.82

t=1

V=0

Plugging the values

H*0.5=0+0.5*9.82*1^2

H=9.82 m

Which one of the following is a decomposition reaction?

BabaBlast [244]

You would know a decomposition reaction occurred if the reactants separated. For example from AB → A+B.

Now if you look at your options only 1 works out for that equation. Letter A.
From the compound K2CO3 it split up to K2O +CO2

It cannot be letter B because synthesis/combination occurred. The same goes for letter C. Letter D, single displacement occurred.

Again, the answer is A.
