What impact does weathering have on soil formation? *
fast

a. chemical weathering adds chemicals to the soil.
b. rocks are broken down into smaller pieces, and finally into sediment.
c. mechanical weathering adds ice to the soil, which turns into water
d. volcanic eruptions contribute metamorphic rocks to the soil

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
