Answer: materials and design Techniques that reduce the negative environmental impact of a structure
Explanation:
In a simple distillation setup, the sequence of equipment from the bench top to the round bottom flask is:
- Thermometer
- Distillation flask
- Round bottom flask
- Bunsen burner
<h3>What is Distillation?</h3>
This is the process in which a mixture is separated through selective boiling and condensation.
The distillation flask and liebig condenser are usually located above the round bottom flask in the set up.

Answer:molten iron
Explanation:releases heat and light into surroundings
Answer:
The answer to your question is 280 g of Mg(NO₃)₂
Explanation:
Data
Efficiency = 30.80 %
Mg(NO₃)₂ = ?
Magnesium = 147.4 g
Copper (II) nitrate = excess
Balanced Reaction
Mg + Cu(NO₃)₂ ⇒ Mg(NO₃)₂ + Cu
Reactants Elements Products
1 Mg 1
1 Cu 1
2 N 2
6 O 6
Process
1.- Calculate the theoretical yield
Molecular weight Mg = 24
Molecular weight Mg(NO₃)₂ = 24 + (14 x 2) + (16 x 6)
= 24 + 28 + 96
= 148 g
24 g of Mg -------------------- 148 g of Mg(NO₃)₂
147.4 g of Mg ------------------- x
x = (147.4 x 148) / 24
x = 908.96 g of Mg(NO₃)₂
2.- Calculate the Actual yield
yield percent = 
Solve for actual yield
Actual yield = Yield percent x Theoretical yield
Substitution
Actual yield = 
x 908.96
Actual yield = 279.95 ≈ 280g
So we just need to do some conversions. We can convert gallons (gal)---> liters (L) just using a few conversion factors and some simple stoichiometry.
Here are the conversion factors:
1 gal= 3.78541 L
Here is how to do the problem:
12 gal x 3.78541 L/1 gal = 45.4249 L
The final answer with significant figures (there are two significant figures) is:
45 L
