Answer:
The final temperature of the water is 28.98 degree Celsius.
Explanation:
It is given that,
Mass of sample of water, m = 52 grams
Initial temperature,
Heat absorbed,
The specific heat of water is
We need to find the final temperature of the water. The heat absorbed is given by the formula as follows :
So, the final temperature of the water is 28.98 degree Celsius.

Answer:
1. Ok, so you have a 1:1 ratio of FeCl2 to FeCl3, which is shown by the fact that if you react 2 moles of FeCl2 you get 2 moles of FeCl3. So therefore, if you react 4 moles of FeCl2, you'd form 4 moles of FeCl3.
2. You have a 1:2 ratio of Cl2 to FeCl2, for every 1 mole of Cl2, you need 2 moles of FeCl2, so therefore, for 7 moles of Cl2, you need 2x7moles = 14 moles
3. 1:1 ratio. So you start with 2.28moles.
4. 1:2 ratio of Cl2 to FeCl2, so therefore to get from FeCl2 to Cl2 you need to divide by 2. Therefore, you need 3.25moles / 2 = 1.625 moles
