Answer:
CHALLENGE ACCEPTED!
Explanation:
Basically, Le Chatelier's principle is the equilibrium law used to predict the effect of a change in conditions on some chemical equilibra. It is often used to increase the yield of reactions.
The final temperature of the mixture in the coffee cup calorimeter is; 19.467 °C
According to the law of energy conservation:
As such; the heat transfer in the liquid water is equal to heat gained by the ice
Heat transfer by liquid water is therefore;
- DH = 6.02 kJ/mol) = 150 × 4.18 × (T1 - T2)
- 6020 J/mol = 627 × (20 - T2)
However, since 18g of water makes one mole
- 6020 J/mol = 6020/18 = 334.44 J/g.
T2 = 19.467°C

Answer:
C. three substances i believe
Explanation:
lmk if im wrong (im sorry if i am!!) But its because the first pic, its a solid substance, 2nd pic is a liquid substance and 3rd pic is condensation or like gas.
