The error is in the formula is bracket so the correct is Mg(OH)₂

The incorrect or error in the formula is bracket that would be that the compound contain only 1Mg atom and 1 oxygen atom and 2 hydrogen atom but is wrong when you write it in an electron dot diagram you will see that it is wrong there be unshared paired of electron and the correct formula is Mg(OH)₂

Know more about Mg(OH)₂

What effect does a) increasing the total pressure and b) increasing the temperature have on the equilibrium H2(g) CO2(g) D H2O(g
Rama09 [41]

Answer:

d. a) no change in the equilibrium and

   b) equilibrium shifts towards products.

Explanation:

Hello.

In this case, for the reaction:

H_2(g) +CO_2(g) \rightleftharpoons H_2O(g)+ CO(g);\ \ \ \ \Delta H=41.2kJ/mol

Which is endothermic due to the positive enthalpy of reaction. In such a way, based on the Le Chatelier's principle which states that increasing the temperature of an endothermic chemical reaction shifts the equilibrium towards products as heat is understood as a reactant, we can see, this is the case.

Moreover, since the change in the number of gaseous moles in the chemical reaction (coefficients balancing the reaction) is 0 (1+1-1-1), we can see that increasing the total pressure does not have any effect over equilibrium.

Therefore answer is d. a) no change in the equilibrium and b) equilibrium shifts towards products.

Best regards!
