Consider the reaction
<span>2Al(OH)3(s)→Al2O3(s)+3H2O(l) </span>
<span>with enthalpy of reaction </span>
<span>ΔHrxn∘=21.0kJ/mol </span>
<span>What is the enthalpy of formation of Al2O3(s)? </span>
<span>Substance ΔHf∘ (kJ/mol) </span>
<span>HCl(g) −92.0 </span>
<span>Al(OH)3(s) −1277.0 </span>
<span>H2O(l) −285.8 </span>
<span>AlCl3(s) −705.6 </span>
<span>H2O(g) −241.8</span>
An ionic bond will most likely form
covalent bonds form when an electron is shared and ionic bonds form when an electron is transferred
It would be more beneficial than acid rain because it is non-corrosive. Its pH is neutral. It would help to dilute acid and alkaline materials and would wash away impurities. Animals, including humans, can drink pure water, but acid rain is harmful. Plants and the soil can accept pure water which aid in supplying plants with water they can absorb directly, and water can dissolve certain nutrients that can then be more readily absorbed by plants, vegetation and microbes living in the soil. Pure water can be stored (reservoir) without the need for filtering or purifying, so reducing costs in providing drinking water. Pure water is part of the natural cycle. It evaporates leaving no deposit.
Answer:
Yes the reaction occur when aqueous solutions happened
In exothermic reactions, there is a release heat and the replacement of weak bonds with stronger ones.
