Oxygen has an oxidation state of -2 so considering that there are 2 oxygen atoms,
2 x -2 = -4
The compound is neutrally charged so the sum of all the oxidation states must be zero. Therefore the oxidation state of Ge must be +4 in order to cancel the -4 to make zero.
The "Nucleus" is the brain of the cell bc it holds the information needed to conduct most of the cell's functions

All atoms except H and O are balanced.
The oxidation number of Cl changes from 7 to 3. The change in the oxidation number is 4.
The oxidation number of O changes from -1 to 0. The change in oxidation number per O atom is 1.
Total change in the oxidation number for 2 oxygen atoms is 2.
To balance the increase in oxidation number with decrease in the oxidation number, multiply H

The oxygen atoms are already balanced.
This is the balanced chemical equation
To determine the heat required to raise a body's termperature by a certain number of degrees C, we use the equation,
H = mcpdT
where m is mass, cp is specific heat, and dT is the temperature difference. Substituting the known values,
H = (30.0 g)(0.90 J/gC)(75 - 25)
H = 1350 J
Thus, there is a need for 1350 J of heat for the process.
Your answer would be C. Potential energy is when your withholding the action and are about to carry through with the action
