Answer:
2 atm
Explanation:
From the question given above, the following data were obtained:
Initial volume (V₁) = 16.0 L
Initial pressure (P₁) = 0.5 atm
Final volume (₂) = 4 L
Final pressure (P₂) =?
The final pressure of the gas can be obtained by using the Boyle's law equation as illustrated below:
P₁V₁ = P₂V₂
0.5 × 16 = P₂ × 4
8 = P₂ × 4
Divide both side by 4
P₂ = 8 / 4
P₂ = 2 atm
Thus, the final pressure of the gas is 2 atm
Answer:

Explanation:
m/s is the unit for speed, so (m/s)/s is the rate of change of speed.
The rate of change of speed is acceleration.
B), C), and D) are wrong. They all have the units of m/s.
Answer: The metal probably increases reaction rate by either holding reactant molecules in the correct orientation to react or by weakening or breaking bonds in reactant molecules to make them more reactive.
This is an example of heterogeneous catalysis.
Explanation: It is heterogeneous catalysis because the catalyst is a solid and the reactants are gases. In heterogeneous catalysis, the catalyst is in a different phase than the reactants.
