the same
Explanation:
Within the nucleus of individual atoms of the same element, the proton number is the same.
All atoms of the same kind from the same element have the same number of protons.
The number of protons does not change, it remains fixed after a chemical reaction.
Different elements have different number of protons that typifies and makes them unique.
But atoms of the same element have the same number of protons in them.

The third one down: "When barium hydroxide is mixed with ammonium chloride, ice crystals form on the outside of the container."
This is because an endothermic reaction [process] takes in more energy than it releases. Therefore because a decrease in energy leads to a decrease in temperature, the ice crystals forming show that it must be a endothermic reaction [process].
Hope this helps! :)

Explanation:
<u>Force formula</u>
The force formula is defined by Newton's second law of motion: Force exerted by an object equals mass times acceleration of that object: F = m ⨉ a. To use this formula, you need to use SI units: Newtons for force, kilograms for mass, and meters per second squared for acceleration.
<u>Equilibrium</u>
It is a state of rest or balance due to the equal action of opposing forces. equal balance between any powers, influences, etc.; equality of effect. mental or emotional balance; equanimity: The pressures of the situation caused her to lose her equilibrium.<u>
