Answer : The correct option is, 
Explanation :
- Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. That means, the loss of electrons takes place.
Or we can say that, oxidation reaction occurs when a reactant losses electrons in the reaction.
- Reduction reaction : It is defined as the reaction in which a substance gains electrons. That means, the gain of electrons takes place.
Or we can say that, reduction reaction occurs when a reactant gains electrons in the reaction.
According to the electrochemical series,
most likely to be reduced because
Hence, the ion most likely to be reduced is
.
Noble gases:) they are very non-reactive
The pH of the solution is used to estimate the acidic and the alkaline condition. The pH paper can be used to determine the conditions. The compound with pH 13.3 is basic.
<h3>What is pH?</h3>
The concentration of the hydrogen or the hydroxide ion in the water gives the estimate of the pH. The potential and the amount of hydrogen decide the acidic and the basic compound.
The pH scale ranges from 0-14 where the scale of 0-6 is acidic, 7 is neutral and 8-14 is basic. If the substance shows a pH of 13.3 then it will lie in the basic range.
Therefore, the compound with a pH of 13.3 is basic.

Given parameters:
Density = 2.7g/cm³
Length of the cube = 10cm
Unknown:
Mass of the cube = ?
Solution:
Density is the mass per unit volume of a substance.
Density =
Mass = density x volume
We need to find the volume of the cube;
Volume of the cube = L³
where L is the length of the cube;
Volume of the cube = 3³ = 27cm³
So, the mass of the granite = 2.7 x 27 = 72.9g
The granite has a mass of 72.9g
