Which equations shows the complete dissociation of a strong base?

1 answer:

4 0

The correct answer is the fourth option. The complete dissociation of a strong base is BOH + h20 -> B+ + OH- + H20 since this is the only base from the choices given. A base is a substance that accepts hydrogen ions.

fredd [130]

Answer:

Wind

Explanation:

Most conifers and about 12% of the world's flowering plants are wind-pollinated. Wind pollinated plants include grasses and their cultivated cousins, the cereal crops, many trees, the infamous allergenic ragweeds, and others. All release billions of pollen grains into the air so that a lucky few will hit their targets.

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!
