Question 1 Not yet answered A reaction in a beaker happens and the surroundings get colder, select all that apply: Points out of 1.00 Select one or more: a. Energy is released b. It is exothermic c. It is endothermic d. Energy is absorbed Flag question Question Given is the following reaction CaCl-Ca2+ 2 CI Calculate the heat of reaction. Use the values in the exercise to do so. Not yet answered Points out of 1.00 Flag question Select one: a. -82 kJ/mol b. 82 kJ/mol c. 55.4 kJ/mol d.-55.4 kJ/mol e.-45.4 kJ/mol f. 45.4 kJ/mol

Explanation / Answer

1)
Surrounding gets colder
This means surrounding is losing heat and system must be absorbing heat
So, d is correct

Reactions that absorbs heat is endothermic and those which release heat. are exothermic
so, c is correct

Answer: c and d

2)
What are values in exercise
