CO2 (s) + CO2 (g)
This is a physical change because only the state of matter changes, not the chemical makeup.
Some electric cars are hybrid which consume less gas than your average car.
They will use electricity to run instead of gas which helps the environment
Answer:
Explanation:
Hello!
In this case, given the change in volume and pressure of the gas, it is possible for us to recall the Boyle's law as way to understand the inversely proportional relationship between pressure and volume:
Thus, when solving for the final pressure, P2, given the initial pressure and volume and the final volume, we obtain:

Molar mass arsenic = 74.92 g/mol
1 mole ---------- 74.92 g
? mole ----------- 1.90 g
moles = 1.90 * 1 / 74.92
= 0.02536 moles of arsenic
hope this helps!
