Answer:
A: molar ratio
Molar ratios state the proportions of reactants and products that are used and formed in a chemical reaction.
Sand dunes would be created due to the mixture falling on each other
x
Answer:
Because after increasing of temperature kinetic energy of molecules increases and reaction speed increases in forward or reverse direction.
Explanation:
Are produced 72 grams of water in this reaction.
<h3>Mole calculation</h3>
To find the value of moles of a product from the number of moles of a reactant, it is necessary to observe the stoichiometric ratio between them:

Analyzing the reaction, it is possible to see that the stoichiometric ratio is 1:2, so we can perform the following expression:



So, if there are 2 mols of Ca(OH)2:
Ca(OH)2 | H2O


Finally, just find the number of grams of water using your molar mass:


So, 72 grams are produced of water in this reaction.
