Answer : The correct option is, $H_3O^+$

Explanation :

Acid : It is a substance that has ability of donating proton or hydrogen ion, $H^+$ .

The general acid dissociation reaction will be,

$HX\rightarrow H^++X^-$

As per question, when the positive hydrogen ions bonded to the water molecule then it forms hydronium ion.

The balanced reaction will be,

$H^++H_2O\rightarrow H_3O^+$

Hence, the ion formed is, $H_3O^+$

Answer:

H₃O⁺.

Explanation:

When H⁺ is bonded to water molecule, it forms hydronium ion:

H⁺ + H₂O → H₃O⁺.

Does the amount of methanol increase, decrease, or remain the same when an equilibrium mixture of reactants and products is subj

denis23 [38]

Answer:

a. Methanol remains the same

b. Methanol decreases

c. Methanol increases

d. Methanol remains the same

e. Methanol increases

Explanation:

Methanol is produced by the reaction of carbon monoxide and hydrogen in the presence of a catalyst as follows; 2H2+CO→CH3OH.

a) The presence or absence of a catalyst makes no difference on the equilibrium position of the system hence the methanol remains constant.

b) The amount of methanol decreases because the equilibrium position shifts towards the left and more reactants are formed since the reaction is exothermic.

c) If the volume is decreased, there will be more methanol in the system because the equilibrium position will shift towards the right hand side.

d) Addition of helium gas has no effect on the equilibrium position since it does not participate in the reaction system.

e) if more CO is added the amount of methanol increases since the equilibrium position will shift towards the right hand side.

Match each subscript symbol to its correct meaning.

ad-work [718]

Answer: (g) - gas, (l) - liquid and (aq) - aqueous solution.

Explanation: The reactants are written in terms of their chemical formula on the left hand side of the arrow and the products are written in terms of their chemical formula on right hand side of the arrow.

The chemical symbols are followed by their physical states such as (l) for liquid, (s) for solid, (g) for gas and (aq) for aqueous.

$H_2(g)+\frac{1}{2}O_2(g)\rightarrow H_2O(l)$
