Answer:
120.44 × 10²³ molecules
Explanation:
Given data:
Moles of C₃H₈ = 5.0 mol
Molecules of water produced = ?
Solution:
Chemical equation:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
Now we will compare the moles of C₃H₈ and water.
C₃H₈ : H₂O
1 ; 4
5 : 4×5 = 20 mol
Molecules of water:
1 mole = 6.022 × 10²³ molecules
20 mol×6.022 × 10²³ molecules / 1 mol
120.44 × 10²³ molecules

Answer:
A decrease in temperature would decrease kinetic energy, therefore decreasing collisions possible.
Explanation:
A gas at a fixed volume is going to have collisions automatically. If you decrease the temperature (same thing as decreasing kinetic energy) you are cooling down the molecules in the container which gives them less energy and "relaxes" them. This decrease in energy causes them to move around much slower and causing less collisions, at a much slower rate. In a perfect world, these collisions do not slow down the molecule but we know that they do, just a very very small unmeasurable amount.
