Metamorphic rock can form from sedimentary rocks , matamorphic rocks, and igneous rocks. 

Answer: sedimentary rock , metamorphic rock and igneous rock. 
IrinaVladis [17]3 years ago
5 0

The answer is:

Sedimentary rock, metamorphic rock, and igneous rock.

<u>If you'd like to know why:</u>

Any type of rock can be a metamorphic rock. Metamorphic rocks are formed when a rock (any kind of rock) undergoes immense heat and pressure. If melting does not occur, it will become a metamorphic rock. If it melts, it becomes magma and from there, the magma, could eventually become an igneous rock and the rock cycle will start again.

If heat transfers from the system (solute) to the surroundings (solvent), then AH is
balu736 [363]

Answer:

B) exothermic.

Explanation:

Hello!

In this case, we need to keep in mind that exothermic reactions release heat, so they increase the temperature as the final energy is less than the initial energy; in contrast, endothermic reactions absorb heat, so they decrease the temperature as the final energy is greater than the initial energy.

In such a way, when a dissolution process shows off a negative enthalpy of dissolution, we infer it is an exothermic process due to the aforementioned; therefore, the answer is:

B) exothermic .

Best regards!
