How is the enthalpy of reaction shown in this potential energy diagram?

Snowcat [4.5K]

Answer : The correct option is C.

Explanation :

Enthalpy of reaction : It is defined as the changes in heat energy takes place when reactants go to products. It is denotes as $\Delta H$ .

$\Delta H$ = Energy of product - Energy of reactant

$\Delta H$ is positive when heat is absorbed and the reaction is endothermic.

$\Delta H$ is negative when heat is released and the reaction is exothermic.

In the given potential energy diagram, the energy of product at higher level and energy of reactant at lower level. The $\Delta H$ for this reaction will be positive.

So, the enthalpy of reaction is defined as the difference of the energy of the reactants and the energy of the products.

What is the molarity (M) of the following solutions?

Dennis_Churaev [7]

Answer:

The molarity (M) of the following solutions are :

A. M = 0.88 M

B. M = 0.76 M

Explanation:

A. Molarity (M) of 19.2 g of Al(OH)3 dissolved in water to make 280 mL of solution.

Molar mass of Al(OH)3 = Mass of Al + 3(mass of O + mass of H)
