I believe the correct answer would be the last option. The rock cycle is driven by the movement of tectonic plates. The rock cycle describes the different changes that a rock undergoes as a result of the geological processes that happens in the Earth and the movement of the plate tectonics is one of these.
Minerals, Because when wind blows everything and crushes rocks into minerals.
Please make me brainy answer
"For example; water is a covalent compound which is formed by the covalent bonding between hydrogen and oxygen atoms."
Answer:
I have no Idea please give more context to your question.
Explanation:
For this problem, we use the Hess' Law.
ΔHrxn = ∑(ν*Hf of products) - ∑(ν*Hf of reactants)
The ν represents the corresponding stoichiometric coefficients of the substances, while Hf is the heat of formation. For pure elements, Hf = 0.
Hf of Al₂O₃ = <span>−1676.4 kJ/mol
</span>Hf of Fe₂O₃ = <span>-826.0 kJ/mol
Thus,
</span>ΔHrxn = 1*−1676.4 kJ/mol + 1*-826.0 kJ/mol
<em>ΔHrxn = -2502.4 kJ/mol</em>
