7.60 moles of magnesium perchlorate 3 significant figures
1 answer:
The number of moles of Mg, Cl, and O atoms is 7.60 moles of magnesium perchlorate 7.60, 15.2, and 60.8 moles respectively.
<h3>What is the mole?</h3>Mole is a standard scientific unit that is used to measure large quantities of small things such as atoms, molecules, atoms, etc. A mole is the amount of a substance that contains 6.023× 10²³ particles of a substance.
The number 6.023× 10²³ is also known as the Avogadro number and is designated by the symbol .
The total number of atoms in every molecule of magnesium perchlorate needs to calculate. The chemical formula of the magnesium perchlorate is Mg(ClO₄)₂.
Therefore the number of atoms of magnesium, chlorine, and oxygen are 1, 2, and 8 respectively. Then, the number of moles of Mg, Cl, and O in 7.60 moles of magnesium perchlorate will be equal to :
Number of moles of Mg = 1 × 7.60 moles = 7.60 mol
Number of moles of Mg = 2 × 7.60 moles = 15.2 mol
Number of moles of Mg = 8 × 7.60 moles = 60.8 mol
Therefore, the number of moles of Mg, Cl, and O in 7.60 moles of Mg(ClO₄)₂ is 7.60, 15.2, and 60.8 moles respectively.

Explanation:
Hello,
In this case, the change in the entropy, by knowing the change in the enthalpy and the temperature for a vaporization process is given by:
Thus, we start by computing the change in the enthalpy for the 3.3g of dichloromethane as shown below:
Finally, the change in the entropy, considering the temperature in kelvins:
Best regards.
Explanation:
A chemical equilibrium is defined as the state of reaction in which the rate of forward reaction is equal to the rate of backward reaction.
When Q > , then it means that the reaction is proceeding in the backward reaction. Whereas if Q <
, then it means that the reaction is proceeding in the forward direction. Hence, formation of products will be favored.
On the other hand, if Q = , then it means reaction is at equilibrium.
At equilibrium, it is not necessary that the concentrations of products divided by the concentrations of reactants equals one.
Thus, we can conclude that the statement for a chemical system at equilibrium, the forward and reverse rates of reaction are equal, is correct.
