Answer:
Q = 44.5 kJ
Explanation:
Given that,
Mass of water, m = 112 g
Water at 50.0°C cools to form ice at −45.0°C
We need to find the total amount of heat released. The formula for heat released is given by :
c is the specific heat of water, c = 4.184 J/g°C
So,
or
Q = -44.5 kJ
So, 44.5 kJ of heat is released.
Based on the mole ratio of the reaction, 30 moles of NO2 will be produced from 15 moles of oxygen.
<h3>What is mole ratio of a reaction?</h3>
The mole ratio of a reaction is the ratio in which moles of reactants combine with themselves to form moles of products.
The equation of the reaction is given below:
The mole ratio of NO2 to oxygen is 2 : 1
Molles of NO2 produced from 15 moles of O2 = 15 × 2 = 30 moles
Therefore, 30 moles of NO2 will be produced from 15 moles of oxygen.
