The decomposition of nh4hs is endothermic: nh4hs(s)⇌nh3(g)+h2s(g) part a which change to an equilibrium mixture of this reaction results in the formation of more h2s? which change to an equilibrium mixture of this reaction results in the formation of more ? a decrease in the volume of the reaction vessel (at constant temperature) an increase in the amount of nh4hs in the reaction vessel an increase in temperature all of the above

Explanation:

According to Le Chatelier's principle, any disturbance caused in an equilibrium reaction will shift the equilibrium in a direction that will oppose the change.

As the given reaction is as follows.

(a)  When increase the temperature of the reactants or system then equilibrium will shift in forward direction where there is less temperature. It is possible for an endothermic reaction.

Thus, formation of will increase.

Hence, formation of will decrease with decrease in volume.

Thus, we can conclude that formation of will increase then.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

b.

the accuracy of the data.
