Q:

$\frac{1}{8}$ as a decimal?

A) 0.375	B) 0.247
C) 0.214	D) 0.125

Answer & Explanation Answer: D) 0.125

Explanation:

Here $\frac{1}{8}$ in decimal means 8th part in 1.

We know that $\frac{1}{10}$ = 0.1

Then, $\frac{1}{8} = ?$

=> $? = \frac{\frac{1}{8} x 0.1}{\frac{1}{10}} = \frac{0.1 x 10}{8} = \frac{0.5}{4} \frac{1}{8} = 0.125$

Q:

$Mg + O_{2} = MgO$

Balance the above Chemical equation?

A) 2Mg + O2 ----> 2MgO	B) 2Mg + O ----> 2MgO
C) 2Mg + O ----> MgO2	D) 2Mg + O2 ----> MgO2

Answer & Explanation Answer: A) 2Mg + O2 ----> 2MgO

Explanation:

Given Equation is

$Mg + O_{2} \to MgO$

Balancing the Chemical Equation is nothing but Conservation of Matter. As Matter is Neither created nor Destroyed, it must be conserved.

Here we have 1 Mg and 2 O on the left side and 1 Mg and 1 O on the right side

To balance that, add 1 Mg on the left side so that it becomes 2 Mg and 2 O on the left side

i.e,

$2 Mg + O_{2} \to 2 MgO$

Here it has 2 Mg & 2 O on the left side and 2 Mg and 2 O on the right side and the Chemical equation is Balanced.
