Answer: zinc is the reducing agent.

Explanation:

1) Reducing agent is the agent that releases electrons, is oxidized (its oxidation number increases)   and causes the reduction of the other agent (the reduced spices reduces its oxidation state).

2) Chemical equation:

Zn(s) + HCl (aq) → H2(g) + ZnCl2(s)

3) determine the oxidation states of each spices

Zn (s): oxidation state = 0
Zn in ZnCls: oxidation state = + 2.

Therfore Zn was oxidized and is the reducing agen.

H in HCl: oxidtation state = +1

H in H2: oxidation state = 0

Therefore H2 was reduced (it is the oxidizing agent).

A white crystalline salt conducts electricity when it is melted and when it dissolves in water.
sergeinik [125]

Answer: Option (a) is the correct answer.

Explanation:

Ionic salts are defined as the salts which tend to contain ionic bonds as there occurs transfer of electrons between its combining atoms.

So, when an ionic salt melts or it is dissolved in water then it will dissociate into its respective ions and as electricity is the flow of electrons or ions. Hence, this salt is then able to conduct electricity.

As covalent compounds are insoluble in water so, they do no dissociate into ions. Hence, they do not conduct electricity.

Similarly, metallic and network solids do not dissociate into ions either when melted or dissolved in water. Therefore, they also do not conduct electricity.

Thus, we can conclude that when a white crystalline salt conducts electricity when it is melted and when it dissolves in water then this bond is of ionic type.

If the bag was made from a metal (like sturdy aluminum foil), do you think it would lose its heat faster or slower than the plas
Luden [163]

I think it would lose its heat faster than the plastic bags because of higher conductivity feature.

<h3>What is conduction?</h3>

Conduction is the process in which heat or electricity is transmitted or transferred through the material of a substance without movement of the material.

We know that metals are good conductors so we can conclude that it would lose its heat faster than the plastic bags bof higher conductivity feature.
