Which best explains the relationship between parent rock and soil composition?

irina1246 [14]

Soil is partially the result of the physical and chemical weathering of its parent rock. The minerals found in the soil were either in that parent rock, or they were formed from the weathering products of the parent rock.

A chemist measures the energy change ΔH during the following reaction: C3H8 (g) +5O2 (g) →3CO2 (g) +4H2O (l) =ΔH−2220.kJ Use the

statuscvo [17]

Answer:

The reaction is exothermic.

Yes, released.

The heat released is 4,08x10³ kJ.

Explanation:

For the reaction:

C₃H₈(g) + 5O₂(g) → 3CO₂(g) + 4H₂O(l)

The ΔH is -2220 kJ, As ΔH is <0, The reaction is exothermic.

As the reaction is exothermic, the heat of the reaction will be released.

The heat released in 81,0g is:

81,0g C₃H₈× $\frac{1mol}{44,1g}$ × $\frac{2220kJ}{1mol}$ = 4,08x10³ kJ

-Using molar mass of C₃H₈ to convert mass to moles and knowing that there are released 2220 kJ per mole of C₃H₈-

I hope it helps!
