Answer:
The answer is 2i on right hand side.
Explanation:
We should star by checking the equation from right.
First we check how many Zn r there in left hand side. Which is 1. Let us check how many Znr there in right hand side, there is 1.So Zn is balanced, and don't worry about Znplus2 on right hand side it is just the ions not how many zinc r there.
Now let us check how many I are there left hand side. Which is 2. Now how many I are there in right hand side? Only 1.
So we put 2 behind I.
Now there r 2 I on both sides.
Its simple actually.

Explanation:
Gravitational potential energy
= mgh = (45kg)(9.81N/kg)(2m) = 882J.
<span>Deciduous forests have a long, warm growing season as one of four distinct seasons.There is abundant moisture.The soil typically is rich. The leaves dropped from trees provide a steady source of organic material for the soil. Many species live in the soil and break down the organic matter.Tree leaves are arranged in strata: canopy, understory, shrub, and ground. A great deal of light is therefore filtered out before it reaches the ground.With the dropping of their leaves during one season, trees stop photosynthesis and enter a dormant period.<span>Three main types of trees are characteristic of these forests: northern hardwood, central hardwood, and southeast pine and oak.
