The mass of an atom and the equivalent of to the number of protons and neutrons in the atom
The volume of O₂ produced: 84.6 L
<h3>Further explanation</h3>
Given
7.93 mol of dinitrogen pentoxide
T = 48 + 273 = 321 K
P = 125 kPa = 1,23365 atm
Required
Volume of O₂
Solution
Decomposition reaction of dinitrogen pentoxide
2N₂O₅(g)→4NO₂(g)+O₂ (g)
From the equation, mol ratio N₂O₅ : O₂ = 2 : 1, so mol O₂ :
= 0.5 x mol N₂O₅
= 0.5 x 7.93
= 3.965 moles
The volume of O₂ :
Answer:
Explanation:
Calories is a unit to measure the amount of energy contained in a particular food product. It is regarded as the energy required to raise the temperature of 1g of water by 1°C.
It is important note that calories measures the heat content of food we eat and consume. Therefore, there is a direct relationship between the release of energy as heat and the calories. The more the calories, the more the energy that would be released as heat.
Just pay attention in school big bones, stop asking people because if they mislead you that will not be good for you're college education.
