D. Adding more of the chemical will heat the water but only up to a certain temperature

<h3>Further explanation</h3>

Chemical changes are changes in the process that produce new substances that are different from the initial/ forming substances. Chemical changes are usually known as chemical reactions. So there are products/reactions and reactants and there is a change in the molecule/particle

The chemical reaction is usually followed by the release of heat, gas, change in color, precipitate substance etc

The heat that occurs in the addition of chemicals is caused by the reaction with water. But there is a constant rise in temperature when water reaches <em>its maximum capacity to react with these chemicals.</em>

Evidenced by the addition of 15 g and 20 g of chemicals, the temperature changes are constant

If the atom has more electrons than protons, it is a negative ion or ANION. If it has more protons than electrons, it is a positive ion.

Explanation:

Positive ions are typically metals or act like metals. Many common materials contain these ions. Mercury is found in thermometers, for instance, and aluminum is a metal that is found in a surprising amount of things.

Write the balanced molecular, ionic, and net ionic equations for the reaction when a solution of lithium phosphate is mixed with
Kaylis [27]

Answer:

see explaination

Explanation:

Molecular equation;

2Li3PO4(aq) + 3CaCl2(aq) >>>> Ca3(PO4)2(s) + 6LiCl(aq)

Total ionic equation; . Includes all ions ;

6Li^+(aq) + 2PO4^-3(aq) + 3Ca^+2(aq) + 6Cl^-(aq) >>>> Ca3(PO4)2(s) + 6Li^+(aq) + 6Cl^-(aq)

Net ionic equation; remove common ions from total ionic;

2PO4^-3(aq) + 3Ca^+2(aq) >>>> Ca3(PO4)2(s)
