<u>Answer:</u> The amount of heat released is 56 MJ.
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
Given mass of 
= 12 kg = 12000 g (Conversion factor: 1 kg = 1000 g)
Molar mass of = 30 g/mol
Putting values in above equation, we get:
The chemical reaction for hydrogenation of ethene follows the equation:
By Stoichiometry of the reaction:
When 1 mole of ethane releases 140 kJ of heat.
So, 400 moles of ethane will release = 
of heat.
Converting this into Mega joules, using the conversion factor:
1 MJ = 1000 kJ
So, 
Hence, the amount of heat released is 56 MJ.
Answer:
exothermic
Explanation:
This chemical reaction is an exothermic reaction because heat is liberated into the environment.
In organic chemistry, the reaction is termed a combustion reaction. In such a reaction, a fuel combines with oxygen to produce carbon dioxide and water.
It is an energy transformation from chemical energy to heat energy.
- An exothermic reaction is one in which heat is liberated to the surrounding.
- The surrounding becomes hotter at the end of the reaction.
In the reaction depicted, heat is liberated.
<span>While driving your rental car on your trip to Europe, you find that you are getting 9.7 kilometers per liter of gasoline. We know that 1 mile is equal to 1.609 kilometers. So divide 9.7 kilometers by 1.609 kilometrs/mile and you will get 6.03 miles per gasoline</span>
Answer:
<u>Volume versus temperature, because they are also directly proportional</u>
Explanation:
The <u>Ideal Gas Equation</u> is :
<u>Evaluating the options</u>
- V ∝ P [Incorrect, because V ∝ 1/P, and graph will be a parabola]
- V ∝ T [Correct, because V ∝ T, and graph is a straight line]
- V ∝ 1/P [Incorrect, because graph is not similar]
- V ∝ 1/T [Incorrect, because V ∝ T]
