<h3><u>Answer;</u></h3>
Ionic
Powdered sports drink is<u> ionic </u>
<h3><u>Explanation;</u></h3>
- <em><u>Sports drinks are beverages whose purpose is to help athletes replace water, electrolytes, and energy before and after training or competition.</u></em>
- Sport drinks contain may contain water, fuel and electrolytes which are used to regulate fluid balances in the body. Electrolytes are molecules that have electrical charge called ions, such as calcium , potassium, sodium and chloride ions.
- <em><u>Ionic compounds are made up of ions, that is positively charged ions and negatively charged ions which are joined together by ionic bonds. Electrolyte in sport drinks forms ionic bonds.</u></em>
I think the correct answer from the choices listed above is option 2. When the products of a reaction are hotter than the reactants the reaction is endothermic. The change in temperature is a measure of energy difference of the states. Since energy must be conserved, so there must be a source of energy for the system.
