Enter the balanced NET IONIC equation for the potentially unbalanced equation AgNO3(aq)+NaCl(aq)→AgCl(s)+NaNO3(aq).

Explanation:

Hello!

In this case, since the net ionic equations are ionic representations of the molecular equation in which the spectator ions (those at both reactants and products sides) are cancelled out, we first write the complete ionic equation for this reaction, considering that the solid silver chloride is not ionized due to its precipitation:

Whereas the nitrate and sodium ions are cancelled out for the aforementioned reason as they are the spectator ions, to obtain:

Which is the required net ionic equation.

a.) chemical energy into thermal energy

Explanation: Chemical energy is the energy stored in the bonds of molecules.

Thermal energy is the energy possessed by a body by virtue of its temperature.

Mechanical energy is the energy possessed by a body by virtue of its position and motion.

Electromagnetic energy is the energy that can be reflected or emitted from objects through electrical or magnetic waves traveling through space.

When natural gas i.e methane is used , the chemical energy stored in the bonds of methane converts to thermal energy which makes the molecules of water gain kinetic energy and move faster.
