Answers
The number of btus that are needed to cool lucia’s apartment is 20,400 btus.
BTUs neededFirst step
Left side=12×10×20
Left side=2400 cubic feet
Middle =16×10×(20-9)
Middle =16×10×11
Middle =1,760 cubic feet
Right side=20×10×20
Right side= 4000 cubic feet
Second step
BTUs:
BTUs=(2400+1760+4000)×2.5
BTUs=8160×2.5
BTUs=20,400 Btus
Therefore the number of btus that are needed to cool lucia’s apartment is 20,400 btus.

k = Polygon B/Polygon A
So, we have:
k = 8/5 = 15/12 = 17/13
Evaluate the quotients
k = 1.60 = 1.25 = 1.31
The factors are not equal i.e.

If the radius of a circle is 3. 5 inches, its diameter is inches and its approximate area is square inches
Answers
Answer: 7 Inches
Explanation:
Diameter = 7 inches
Area of circle is 38.46 inches²
Step-by-step explanation:
Given :The radius of a circle is 3.5 inches.
We have to find its diameter and area.
Since diameter is twice of radius.
So radius = 3.5 inches
Diameter = 2× 3.5 inches = 7 inches
Area of circle =
Substitute, r = 3.5
Area of circle = (3.5)
Simplify , we have,
Area of circle = 12.25
Using π = 3.14
We have,
Area of circle = 38.465
Thus, Area of circle is 38.46 inches²
When 70. G of li3n(s) (molar mass 35 g/mol) reacts with excess h2(g), 8. 0 g of lih(s) is produced. The percent yield is closest to
Answers
Answer:
25%
Explanation:
Li3N(s) + 2 H2(g) ⇄ LiNH2(s) + 2 LiH(s)
70 g Li3N x 1 mol Li3N/35 g = 2 mol Li3N
2 mol Li3N x 2 mol LiH/1 mol Li3N
= 4 mol LiH x 7.05 g LiH/1 mol LiH = 28.20
percent yield = actual yield/theoretical yield x 100
8 g / 28.20 g ≈ 28%
28% is closest to 25% ap classrom
When 70. G of li3n(s) (molar mass 35 g/mol) reacts with excess h2(g), 8. 0 g of lih(s) is produced. The percent yield is 25%.
What is the percent yield?The actual yield is calculated as the theoretical yield multiplied by 100 to get the percent yield. There are a variety of reasons why a chemical reaction's actual yield could be lower than its theoretical yield, and they will be covered in more detail in later chapters of the course.
Li₃N(s) + 2 H₂(g) ⇄ LiNH₂(s) + 2 LiH(s)
70 g Li₃N x 1 mol Li₃N/35 g = 2 mol Li₃N
2 mol Li₃N x 2 mol LiH/1 mol Li₃N
4 mol LiH x 7.05 g LiH/1 mol LiH = 28.20
Percent yield = actual yield/theoretical yield x 100
8 g / 28.20 g = 28%
