Physical and chemical changes are reversible and nonreversible changes. The release of carbon dioxide gas indicates a chemical change.
<h3>What is a chemical change?</h3>
A chemical change is a change in which a new substance is produced when the reactants react in the reaction mixture. The chemical produced cannot be reversed back to the reactants and hence, it is nonreversible.
The release of carbon dioxide is a chemical change as limestone and hydrochloric acid react with each other chemically and as a result, a new substance was formed.
Therefore, the production of carbon dioxide indicates a chemical change.

Explanation:
Given that:
Concentration = 1.8 M
Considering the ICE table for the dissociation of acid as:-
The expression for dissociation constant of acid is:
![K_{a}=\frac {\left [ H^{+} \right ]\left [ {CH_3COO}^- \right ]}{[CH_3COOH]}](https://tex.z-dn.net/?f=K_%7Ba%7D%3D%5Cfrac%20%7B%5Cleft%20%5B%20H%5E%7B%2B%7D%20%5Cright%20%5D%5Cleft%20%5B%20%7BCH_3COO%7D%5E-%20%5Cright%20%5D%7D%7B%5BCH_3COOH%5D%7D)
Solving for x, we get:
<u>x = 0.00568 M</u>

<u>Option B is correct.</u>
Answer:
La agricultura intensiva puede eliminar rápidamente los nutrientes del suelo, que generalmente se repara con fertilizantes. La agricultura ecológica normalmente se refiere a no transgénicos
producción y falta de fertilizantes y pesticidas más dañinos. Por lo general, los productos orgánicos se venden a un precio más alto a las personas que creen que los conservantes afectan su salud y bienestar. Los productos intensivos generalmente se venden en grandes cadenas de mercado para obtener grandes ganancias y, por lo general, las frutas transgénicas se pueden producir en casi todas las estaciones.
intensive agriculture can remove nutrients from the soil quickly which is usually remedied by fertilizer. Organic farming normally refers to non-gmo
produce and lack of more harmful fertilizers and pesticides. Usually the organic produce is sold for a higher price to people who believe the preservatives affect their health and well being. Intensive produce is usually sold in large market chains for great profit and usually gmo fruits can be produced in almost all seasons.
