Question 1
Balanced chemical equation
Sum of coefficients = 1 + 8 + 5 + 6 = 20
Question 2
Here, an acid is reacting with the base and thus, this reaction is an acid-base reaction.
Question 3
In order to form a stable ion, magnesium atom losses two electrons and forms Mg+2.
Question 4
The molecule of has two equivalent Lewis structure or resonance structure as shown
below.
Question 5
Name of compound = Aluminium sulfate
1

Formula of compound
Here,
Molar mass of Al = 27
Molar mass of S = 32.1
Molar mass of O = 16
Hence,
Molar mass of Aluminium sulfate = 2 (27) + 3 {32.1 + (16*4)} = 342.3 gram per mole
Question 6
3.75 moles of Cl represent = n grams of Cl
Mass of Cl = 35.5 gram per mole
1 mole has 35.5 gram of Cl
And thus, 3.75 moles would have n = 35.5*3.75 = 133.125 gram of Cl
Question 7
Mass of O = 16
Mass of N = 14
Mass of H = 1
Total mass of 1 mole of
Mass of O in compound = 16*3 = 48
