Identify the correct type of heat transfer for A, B, and C in the picture. Using the picture, cite evidence for your choices.

tatiyna

The correct type of heat transfer for A, B, and C are conduction, convection and radiation respectively.

<h3>What is heat transfer?</h3>

Heat transfer is a process in which amount of heat will be transferred from one object to any other object by various means.

In type A, heat is transferred through conduction process as in this transfer takes place due to direct contact of particles.
In type B, heat is transferred through the convection process as in that process transfer of heat takes place through the medium.
In type C, heat transfer done by the radiation as in that transfer through empty space.

Hence at A, B and C heat transfer done through conduction, convection and radiation respectively.

Write the net ionic equation for the precipitation reaction that occurs when aqueous solutions of potassium hydroxide and nickel

Gnom [1K]

<u>Answer:</u> The net ionic equation is written below.

<u>Explanation:</u>

Net ionic equation of any reaction does not include any spectator ions.

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

The chemical equation for the reaction of nickel (II) acetate and potassium hydroxide is given as:

$Ni(CH_3COO)_2(aq.)+2KOH(aq.)\rightarrow 2CH_3COOK(aq.)+Ni(NO_3)_2(s)$

Ionic form of the above equation follows:

$Ni^{2+}(aq.)+2CH_3COO^-(aq.)+2K^+(aq.)+2OH^-(aq.)\rightarrow 2CH_3COO^-(aq.)+2K^+(aq.)+Ni(OH)_2(s)$

As, acetate and potassium ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.

The net ionic equation for the above reaction follows:

$Ni^{2+}(aq.)+2OH^-(aq.)\rightarrow Ni(OH)_2(s)$

Hence, the net ionic equation is written above.
