Answer:
A condensation reaction
Explanation:
it is also called a dehydration reaction
Answer:
<u><em></em></u>
- <u><em>3.42 moles</em></u>
Explanation:
By the law of conservation of energy, assuming no losses of heat to the surroundings, <em>the amount of heat consumed by the dissolution of the ammonium nitrate is equal to the amount of heat released from the water.</em> This is, the ammonium nitrate absorbs all the heat it needs to break the ions apart and get dissolved from the water in which it is being dissolved.
Thus:
↑ ↑ ↑
heat released number of moles molar heat of solution
from water of NH₄NO₃ for NH₄NO₃
Solve for n and compute:
- n = 88.0kJ / (25.7kJ/mol) = 3.42 moles ← answer
Answer:
(A) 2.7*10^-8, (B)3.56*10^2, (C)4.78*10^4 (D) 9.6*10^-2
Explanation:
Scientific notation is a system that allows you to express very large or very small numbers by multiplying them by multiples of 10 with positive or negative exponents
The number of moles of the water that was evaporated is 12083467.5 moles of water.
<h3>What moles of water is evaporated?</h3>
We know that the number of moles that we have can be gotten as the ratio of the mass to the number of moles of the object. Now we know that from the question, we have the volume of the hydrogen to be 90,000 gallons. We have to convert this volume to liters.
Given that;
1 gallon = 3.79 L
90,000 gallons = 90,000 gallons * 3.79 L/1 gallon
= 341100 L
Then we have the density of the hydrogen to be 70.85 g/L
Mass of the hydrogen = 70.85 g/L * 341100 L
= 24166935 g
Number of moles of the hydrogen reacted = 24166935 g/2 g/mol
= 12083467.5 moles
If 2 mole of hydrogen gives 2 moles of water
12083467.5 moles of hydrogen gives 12083467.5 moles of water
