What is the acceleration that this box will move? (Don't forget your units)

160 I think or 200

Explanation:

the lines are pulling on the same side so you add those

relative humidity is a measure of the amount of moisture in the air relative to the total amount of moisture the air can hold.

so d

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.
