Question

given the balanced equation representing a reaction 2NO+O2->2NO2+energy the mole ratio of NO to NO2 IS

Answer 1

The problem tells us that the equation is already balanced, so we know that we don't have to change any of the coefficients in front of the compounds. Therefore, we can find the ratio by looking at the coefficients of NO and NO²:

2NO : 2NO²

This can be simplified to 1 : 1. Therefore, it is a 1 to 1 ratio.

Answer 2

The mole ratio of NO to NO₂ from the balanced equation is 1 : 1

From the question given, we obtained the following equation:

     2NO + O₂ —> 2NO₂

    2      :    1       :  2

From the balanced equation above,

2 moles of NO reacted with 1 mole of O₂ to produce 2 moles of NO₂

With the above information in mind, we can obtain the mole ratio of NO to NO₂. This can be obtained as follow:

Mole of NO = 2 mole

Mole of NO₂ = 2 moles

Mole ratio =.?

Mole ratio => NO : NO₂ => 2 : 2 = 2 / 2 = 1 / 1

Mole ratio => NO : NO₂ => 1 : 1

Therefore, the mole ratio of NO to NO₂ is 1 : 1
