Answer : The number of moles of oxygen needed to burn are, 1.995 moles

Solution : Given,

Moles of methyl alcohol, CH_3OH = 1.33 mole

The given balanced chemical reaction is,

2CH_3OH+3O_2\rightarrow 2CO_2+4H_2O

From the balanced reaction, we conclude that

As, 2 moles of methyl alcohol react with 3 moles of oxygen

So, 1.33 moles of methyl alcohol react with \frac{3}{2}\times 1.33=1.995 moles of oxygen

Therefore, the number of moles of oxygen needed to burn are, 1.995 moles

<span>2 CH3OH + 3 O2 = 2 CO2 + 4 H2O

2 moles CH3OH ---------------- 3 moles O2
1.33 moles CH3OH ----------- ( moles O2)

moles O2 = 1.33 x 3 / 2

moles O2 = 3.99 / 2

= 1.995 moles of O2</span>

How many moles of CaCO3 are needed to react with 12.5 mol SO2​
grandymaker [24]
<h3><u>Answer;</u></h3>

= 12.5 Moles of CaSO3

<h3><u>Explanation</u>;</h3>

The reaction between CaCO3 and SO2 is given by the equation.

CaCO3(s) + SO2(g) → CaSO3(aq) + CO2(g)

The mole ratio between CaCO3 and SO2 is 1 : 1;

1 mole of CaCO3 reacts with 1 mole SO2 to form CaSO3 and CO2

Therefore;

<em>12.5 moles of SO2 will require 12.5 moles of CaSO3</em>

What is a nonpolar covalent bond?
Vlad1618 [11]

<u>Answer:</u> The correct answer is Option D.

<u>Explanation:</u>

A non-polar covalent bond is defined as the bond which is formed between the atoms having no difference in electronegativity values. For Example: Cl_2,H_2 etc..

In this bond, the electrons are shared equally and \Delta EN value is equal to 0.

Hence, the correct answer is Option D.
