The first one is the answer
isotopes of an atom have different number of neutrons . the number of protons are not different in isotopes of an atom
The pressure is 19.3 N/cm².
<em>p</em> = (28.0 lb/1 in²) × (4.45 N/1 lb) × (1 in²/6.45 cm²) = 19.3 N/cm²
B: The total thermal energy is greater in a large body of water than one much smaller
Explanation:
A large lake filled filled with cool water will have more thermal energy than smaller pond filled with warmer water because the total thermal energy is greater in a large body of water than one that is much smaller.
Thermal energy is a form of kinetic energy usually due to transfer of heat energy.
Amount of heat energy is dependent on the differences in temperature, mass and specific heat capacity of a body.
Both lake water will have the same specific heat capacity. Since larger body of water has more mass, it will possess more thermal energy.

Always remember that pH + pOH = 14
Here, you have a pOH of 11.24, so you replace it in the equation, and u get:
pH + 11.24 = 14
Then, You move 11.24 to the other part. and moving from a part to another change the sign of the equation. And you get:
pH = 14 - 11.24 = 2.76
So, the pH of a solution that has a pOH of 11.24 is pH = 2.76
