It is true because of the hardness differences. if there are differences between other things they don't normally work like fitting a cube into a circle is kinda like trying to scratch something that has a higher hardness.

Given the balanced ionic equation:
bezimeni [28]

Answer : The correct option is, (4) 6.0 mol

Explanation :

The given balanced chemical equation is,

3Pb^{2+}+2Cr\rightarrow 3Pb+2Cr^{3+}

In this reaction, lead undergoes reduction and chromium undergoes oxidation.

Oxidation reaction : It is the reaction in which a substance looses its electrons. In this oxidation state increases.

Reduction reaction : It is the reaction in which a substance gains electrons. In this oxidation state decreases.

Half reactions of oxidation-reduction are :

Oxidation : 2Cr\rightarrow 2Cr^{3+}+6e^-

Reduction : 3Pb^{2+}+6e^-\rightarrow 3Pb

From the reduction reaction, we conclude that 6 moles of electrons gained by the 3 moles of lead ions.

Hence, the correct option is, (4) 6.0 mole

Distinguish between mass and weight
yKpoI14uk [10]

Answer:

There is a basic difference, because mass is the actual amount of material contained in a body and is measured in kg, gm, etc. Whereas weight is the force exerted by the gravity on that object mg. Note that mass is independent of everything but weight is different on the earth, moon, etc.
