Answer:
The correct answer is non-metals.
Explanation:
In the covalent bond, the two non-metallic atoms share one or more electrons, i.e., they bind through their electrons in the last orbital. Covalent bonds normally occur between atoms with similar and elevated electronegativity, from which removing the electron completely requires a lot of energy.

Answer: Option (A) is the correct answer.
Explanation:
A compound is a substance which contains two or more different atoms combined together.
Sodium is found as sodium chloride in nature. Sodium chloride is also known as common salt.
As it contains a sodium atom combined to a chlorine atom, therefore, it is a compound.
Thus, we can conclude that sodium is the element that is found in nature only in compounds.

Given:
12.0 M HCl
2.0 liters of a 3.0 M HCl
Required:
volume of concentrated hydrochloric acid
Solution:
M1V1 = M2V2
(12.0 M HCl)V1 = (3.0 M HCl)( 2.0 liters)
V1 = (3.0 M HCl)( 2.0 liters)/ (12.0 M HCl)
V1 = 0.5 liters

Answer:
0.0798 mol Mg
Explanation:
a) divide the number of grams of magnesium by the molar mass of magnesium found on the periodic table
1.94g Mg/(24.31g Mg/mol Mg)=0.0798 mol Mg
