Answer:
The total pressure in the container is 2 atm (Option B)
Explanation:
Step 1: Data given
The initial pressure of the PCl5(g) is 1.00 atm
Volume of the container = 1.00 L
Step 2: The balanced equation
PCl5(g) ⇋ PCl3(g) + Cl2(g)
Step 3: Calculate the total pressure in the container
1mol of ideal gas has a pressure of 1 atm
If 1 mol of PCl5 completely decomposes into 1 mol PCl3 and 1 mol Cl2
Then the pressure for 1 mol PCl3 and 1 mol Cl2 is for both 1 atm
The total pressure would be 2*1 atm = 2 atm
The total pressure in the container is 2 atm
Answer: Shaun must consume 6 more g of protein to reach the required amount.
Explanation:
Given : Recommended amount of protein = 200 calories
Now 4 calories = 1 gram of protein
Thus 200 calories = 
g of protein.
Calories consumed per day by Shaun = 176 calories
176 calories = 
g of protein.
Thus Shaun need to consume = (50-44) g = 6 of protein to reach the required amount.
Shaun must consume 6 more g of protein to reach the required amount.
Answer:
7.25 mol
Explanation:
Given data:
Number of moles of sodium carbonate formed = ?
Number of moles of carbonic acid = 7.25 mol
Solution:
Chemical equation:
H₂CO₃ + 2NaOH → Na₂CO₃ + 2H₂O
Now we will compare the moles of sodium carbonate with carbonic acid.
H₂CO₃ : Na₂CO₃
1 : 1
7.25 : 7.25
So from 7.25 moles of carbonic acid same number of moles of sodium carbonate will form.
