The potential energy of the ball is 8 J.
<h3>What is mechanical energy?</h3>
Mechanical energy is given as the energy possessed by an object to do work. It is given as the sum of the kinetic energy and potential energy.
Mechanical energy = Kinetic energy + Potential energy
The given ball has:
- Mechanical energy = 25 J
- Kinetic energy = 17 J
The potential energy is given as;
25 J = 17 J + Potential energy
Potential energy = 25 J - 17 J
Potential energy = 8 J
The potential energy of the ball is 8 J.

Answer:
Nonpolar covalent bond
Explanation:
when carbon atoms bonds to its self it form a nonpolar covalent bond
<h3>
Answer:</h3>
3.6 × 10^24 molecules
<h3>
Explanation:</h3>
Concept: Moles and Avogadro's number
- We need to know that one mole of a compound has molecules equivalent to the Avogadro's number, 6.022 × 10^23.
- Therefore; 1 mole of a compound contains 6.022 × 10^23 molecules
In this case;
We are given 6 moles of Methane;
But 1 mole of methane = 6.022 × 10^23 molecules
Therefore;
Molecules = Number of moles × Avogadro's number
= 6 moles × 6.022 × 10^23 molecules/mole
= 3.613 × 10^24 molecules
= 3.6× 10^24 molecules
Thus, there are 3.6× 10^24 molecules in 6 moles of methane.
Explanation:
To determine the charge on a given transition metal atom, you have to consider what element it is, the charges on the other atoms in the molecule, and the net charge on the molecule itself. The charges are always whole numbers, and the sum of all the atomic charges equals the charge on the molecule
