How are science and technology related

KatRina [158]

There is no answer, science is about empirical knowledge, technology is the sum of techniques, skills, methods, and processes. I do not believe that you will find a answer for that.

Enter the balanced complete ionic equation for HCl(aq)+K2CO3(aq)→H2O(l)+CO2(g)+KCl(aq). Express your answer as a chemical equati

<u>Answer:</u> The net ionic equation is given below.

<u>Explanation:</u>

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

These 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 hydrochloric acid and potassium carbonate is given as:

$2HCl(aq.)+K_2CO_3(aq.)\rightarrow H_2O(l)+CO_2(g)+2KCl(aq.)$

Ionic form of the above equation follows:

$2H^+(aq.)+2Cl^-(aq.)+2K^+(aq.)+CO_3^{2-}(aq.)\rightarrow CO_2(g)+H_2O(l)+2K^+(aq.)+2Cl^-(aq.)$

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

The net ionic equation for the above reaction follows:

$2H^+(aq.)+CO_3^{2-}(aq.)\rightarrow CO_2(g)+H_2O(l)$

Hence, the net ionic equation is given above.
