Answer:
How many moles are present in 100.0 g of Al? What is the mass of 0.552 mol of Ag metal? Answer a: 3.706 mol
The expected outcome would be A. The reaction will speed up after adding a catalyst to a chemical reaction.
<u>Answer:</u> 2.00 atm
<u>Explanation:</u>
The gas is kept under the same temperature in this problem. Assuming the amount of gas is constant, we can apply the Boyle's law.
The Boyle's law equation,
P₁V₁ = P₂V ₂
Plug in the values,
1.00 atm x 4.0 L = P₂ x 2.0 L
Simplify,
4.00 atm L = 2 P₂ L
Now flip the equation,
2 P₂ L = 4.00 atm L
Dividing both sides by 2 we get,
P₂ = 2.00 atm
First choice: PhH4 has a lower boiling point
Second: SiF4 higher
Third: CBr4 higher
