Answer:
Answer is in the explanation.
Explanation:
The principal difference between percent recovery and percent yield is that the second involves a chemical reaction whereas the first is more about a purification process.
Thus, percent yield is defined as the ratio between amount of product and theoretical yield.
Percent recovery is the ratio between final amount of purified substance and initial amount of substance.

Answer : The amount of energy evolved during the reaction is, 
.
Solution : Given,
Mass of Al = 51.2 g
Molar mass of Al = 27 g/mole
First we have to calculate the moles of Al.
The balanced combustion reaction is,
From the given reaction, we conclude that
As, 2 moles of Al evolved energy = 
So, 1.896 moles of Al evolved energy = 
Therefore, the amount of energy evolved during the reaction is, .
The plant makes 3.50 × 10⁷ bearings per day
<em>Pounds of bearings</em> = 1 da × (4355 lb bearings/5 da) = 871.0 lb bearings
<em>Grams of bearings</em> = 871.0 lb bearings × (453.6 g bearings/1 lb bearings)
= 3.951 × 10⁵ g bearings
<em>No. of bearings</em> = 3.951 × 10⁵ g bearings × (1 bearing/0.0113 g bearing)
= 3.50 × 10⁷ bearings
Same: Both are natural disasters. Both are becoming more common to due climate change.
Different: Floods are an excess amount of water whereas droughts are a lack of water for a prolonged period of time. Floods are more common in coastal areas whereas droughts are most common in the Midwest and South.
Answer:
True
Explanation:
Because the sun is a star, all stars eventually explode after a certain amount of time
