Answer:
Explanation:
To start with, the mass of a substance is centered on the amount of particles contained in it.
Mass of a substance measure is the same anywhere it is taken.
In chemistry, the concept of mole is used to find the exact estimate of the number of entities in a sample.
A mole of substance is quantity that is used to express the number of particles contained in it.
1 mole of any substance contains the Avogadro's number of particles.
This amount of particles is given as 6.02 x 10²³; the particles can be protons, neutrons, electrons e.t.c.
To find the number of moles;
Number of moles = 
Through this, we clearly ascertain the number of entities in a sample given the mass.
Generally speaking mechanical energy is energy which physically moves (the object), while the thermal energy is energy from the movement of atoms.
Basically temperature is a measurement of atomic movement (doesn't move object as a whole).
Hence heat.
Answer: The gas generated by two antacid tablets has a smaller volume.
Explanation:
Since the antiacid is the limiting reagent, we know that the more tablets there are, the more gas there will be.
This means that there will be more gas generated by the four antiacid tablets when compared to the two antiacid tablets, which gives us that the gas generated by the two antiacid tablets has a smaller volume.
Answer:
6
Explanation:
number of protons equal number of electrons for the atom to be stable
