2) An object accelerates 2.0 m/s2 when a force of 12.0 Newtons is applied to it.
What is the mass of the object
Show your work

Explanation:

The mass of the object can be found by using the formula

f is the force

a is the acceleration

From the question we have

We have the final answer as

Hope this helps you

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.
