Density does not change with the amount of matter.

The density of water is 1 g/mL whether you have 1 mL or 1000 mL of water. Density is an i<em>ntensive </em>property.

Mass, volume, and weight change with the quantity of matter. For example, the mass of 1000 mL of water is greater than the mass of 1 mL of water. Mass, volume, and weight are <em>extensiv</em>e properties.

padilas [110]

Answer: $NiO+CO\rightarrow Ni+CO_2$ : reducing agent is CO.

Explanation:

a) $Fe+Cu^{2+}\rightarrow Fe^{2+}+Cu$

The oxidation state of copper reduces from +2 to 0, it is getting reduced. As $Cu^{2+}$ gets reduced, it acts as an oxidising agent.

The oxidation state of iron increases from 0 to +2. Thus, it is getting oxidized. As $Fe$ gets oxidized, it acts as a reducing agent.

b. $2Na+Cl_2\rightarrow 2NaCl$

The oxidation state of chlorine reduces from 0 to -1, it is getting reduced. As $Cl_2$ gets reduced, it acts as an oxidising agent.

The oxidation state of sodium increases from 0 to +1. Thus, it is getting oxidized. As $Na$ gets oxidized, it acts as a reducing agent.

c. $C+O_2\rightarrow CO_2$

The oxidation state of oxygen reduces from 0 to -2, it is getting reduced. As $O_2$ gets reduced, it acts as an oxidising agent.

The oxidation state of carbon increases from 0 to +2. Thus, it is getting oxidized. As $C$ gets oxidized, it acts as a reducing agent.

d. $NiO+CO\rightarrow Ni+CO_2$

The oxidation state of nickel reduces from +2 to 0, it is getting reduced. As $Ni^{2+}$ gets reduced, it acts as an oxidising agent.

The oxidation state of carbon increases from +2 to +4. Thus, it is getting oxidized. As $CO$ gets oxidized, it acts as a reducing agent.
