Answer:
Element
Explanation:
A chemical element is a substance that contains only one type of atom, which is the smallest particle of an element
I think the answer is true but I'm not very sure
The atoms are all electrically neutral because the number of protons is equal to the number of electrons.
<h3>What is electrical neutrality?</h3>
An atom is electrically neutral when the number of protons is equal to the number of electrons.
In the cases of H-1, H-2, and H-3, the nuclides have one electron an one proton. The different mass numbers arise from differences in the number of neutrons. Hence in all cases, the nuclides are electrically neutral.

Answer:
35.42g
Explanation:
LiOH + KCI → LiCl + KOH
Let us determine the molar mass of LiOH and LiCl. This is illustrated below:
Molar Mass of LiOH = 7 + 16 + 1 = 24g/mol
Molar Mass of LiCl = 7 + 35.5 = 42.5g/mol.
Now, we can obtain the theoretical yield of LiCl as follow:
From the equation above,
24g of LiOH reacted to produce 42.5g of LiCl.
Therefore, 20g of LiOH will react to produce = (20 x 42.5)/24 = 35.42g of LiCl.
From the above calculations, the theoretical yield of LiCl is 35.42g
