Explanation:
As an object falls toward earth, the potential energy of the object: Decreases
<h3>What is the gravitational potential energy towards the earth?</h3>
In this case, the formula for the Potential energy is:
E = Em + Ek + Eg
Where;
Em is energy due to mass
Ek is kinetic energy
Eg is energy due to gravity
Thus, as the potential energy falls toward earth, Eg will approach 0, which will decrease its amount.

Answer:
The balanced equation for reaction of solid cesium with liquid water
= 2Cs + 2H2O → 2CsOH + H2
Explanation:
cesium react with liquid water to produce cesium hydroxide and hydrogen gas
that is 2 moles of Cs react 2 moles of H2O to form 2 moles CsOH and 1 of hydrogen gas
