Write a balanced net ionic equation for the reaction of aqueous solutions of baking soda (nahco3) and acetic acid.(a) hco3–(aq) + ch3co2h(aq) --> ch3co2–(aq) + h2o(l) + co2(g)(b) hco3–(aq) + h+(aq) --> h2co3(aq) (c) hco3–(aq) + h+(aq) --> h2o(l) + co2(g)(d) nahco3(aq) + h+(aq) --> h2co3(s) + na+(aq)2(e) nahco3(aq) + ch3co2h(aq) --> 2 na2co3(aq) + ch4(aq) + 2h2o(l) + co2(g)

The correct answer is Option C.

Explanation:

Net ionic equation of any reaction does not include any spectator ions.

Spectator ions are defined as the ions which does not get involved in a chemical equation. They are found on both the sides of the chemical reaction when it is present in ionic form.

The chemical equation for the reaction of sodium bicarbonate and acetic acid is given as:

Ionic form of the above equation follows:

As, sodium and acetate ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.

The net ionic equation for the above reaction follows:

Hence, the correct answer is Option C.

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
