Answer:
Point out to students that molecules of hot water are moving faster and are slightly further apart. The molecules of cold water are moving slower and are a little closer together. If students do not notice a difference, move the slider all the way to the left again and then quickly to the right.
2. How do molecules move in cold water?
Compare the speed of molecules in hot water compared to molecules in cold water? Water molecules move faster in hot water and slower in cold water. water molecules in cold, room temperature, and hot water. most of the liquid.

Answer:
12 moles of CO₂.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
CO₂ + H₂O —> H₂CO₃
From the balanced equation above,
1 mole of CO₂ dissolves in water to produce 1 mole of H₂CO₃.
Finally, we shall determine the number of moles of CO₂ that will dissolve in water to produce 12 moles of H₂CO₃. This can be obtained as follow:
From the balanced equation above,
1 mole of CO₂ dissolves in water to produce 1 mole of H₂CO₃.
Therefore, 12 moles of CO₂ will also dissolve in water to produce 12 moles of H₂CO₃.
Thus, 12 moles of CO₂ is required.
A 10.0 g piece of metal is placed in an insulated calorimeter containing 250.0 g of water initially at 20.0 °C. If the final temperature of the mixture is 25.0 °C, the heat change of water will be 5230 J.
Weight of metal = 10.0 g
Weight of water = 250.0 g
Initial temperature of water (Ti) = 20.0 °C
Final temperature of water (T2) = 25.0 °C
The specific heat capacity of water is 4.184 J/g.°C
We can calculate the heat change of water by the following equation;
<em>Q = mwater × Cwater × (T2-Ti)</em>
Q = 250.0 g × 4.184 J/g.°C × (25.0 - 20.0) °C
Q = 5230 J
