A student observes poor growth of plants in a garden containing high clay content. Clay content reduces drainage in soil. Which of these is the best method to improve plant growth in the garden? A. water the plants once a month
B. add sand to the soil
C. mix soil with chemicals which absorb the air
D. do not dig or till the soil

Add sand to the soil

Explanation:

Just finished my test

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

the answer is 0.8m.
