Give the net ionic equation for the reaction (if any) that occurs when aqueous solutions of Al(C2H3O2)3 and LiNO3 are mixed. Giv
RSB [31]

Answer: No reaction occurs

Explanation:.

Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.

The given chemical equation is:

Al(C_2H_3O_2)_3(aq)+3LiNO_3(aq)\rightarrow Al(NO_3)_3(aq)+3LiC_2H_3O_2(s)

The complete ionic equation is;

Al^{3+}(aq)+3C_2H_3O_2^-(aq)+3Li^+(aq)+3NO_3^-(aq)\rightarrow Al^{3+}(aq)+3NO_3^-(aq)+3Li^+(aq)+3C_2H_3O_2^-(aq)

The ions which are present on both the sides of the equation are are not involved in net ionic equation.

Hence, there is no net reaction.

Why do cells use fat and starch for long term energy storage instead of ATP molescules?
IceJOKER [234]
ADP is like an uncharged battery. ATP is like a charged battery, ready to provide energy to do work in the cell. The charging of ADP into ATP takes place in the mitochondria. Fat and starch are stable (last a long time) whereas ATP goes dead too quick and will need to be recharged.

glucose is a carbon chain molecule (sugar). When the bonds in the chain are broken, energy is released. That energy is used to turn ADP into ATP. Glucose is the "electricity" used to charge the battery.

What is the energy required to go from liquid to gas called answers?
Tresset [83]
Answer:
            <span>The energy required to go from liquid to gas is called as Latent Heat of Vaporization.

Explanation:
                   The process of conversion of liquid into gas phase is known as vaporization while the conversion of gas into liquid state is called as condensation. The liquid having stronger intermolecular forces than gases require some energy to break those interactions hence, the heat provided to break these interactions and convert it into gas phase is called as heat of vaporization. Remember, heat of vaporization and heat of condensation are same for a given substance but with different signs.

Example:

Heat of Vaporization of Water  =  40.65 kJ/mol

Heat of Condensation of Water  =  - 40.65 Kj/mol</span>
