Evaporation because water absorbs the heat so the particles have more energy and can break away from bonds holding them together (turn to gas)
Chloroethane is the answer
Answer:
0.0300 moles of H₂
Explanation:
The original equation is PV = nRT. We need to change this to show moles (n).
n =
It's important to convert your values to match the constant (r) in terms of units.
30.0 kPa = 0.296 atm
2500 mL = 2.50 L
27 °C = 300 K
Now, plug those values in to solve:
n = - for the sake of keeping the problem clean, I didn't include the units but you should just to make sure everything cancels out :)
Finally, you are left with n = 0.0300 moles of H₂
Answer:
what's the qstn first ?????
Answer:
The particles in a liquid as it freezes slow down.
Explanation:
This is because heat is energy and when there is less heat, there is less energy causing the particles to slow down.
