How do the mass and height of an object affect the gravitational potential energy?
marin [14]

Answer:

B. mass and height have the same effect on gravitational potential energy.

Explanation:

Both mass and height have the same effect on the gravitational potential energy of body.

Gravitational potential energy is the energy of a body due to that of another body. It usually the energy at rest in a body.

It is mathematically expressed as;

 G.P.E  = m x g x h

m is the mass

g is the acceleration due to gravity

h is the height

We see that both the height and mass are directly proportional to the gravitational potential energy and as such, they have the same effect.

What happens when The vapour obtained by dropping conc. H2SO4 in a mixture of KI and MnO2 is treated with hypo solution​
Shalnov [3]

Iodine is decolorized.

The first reaction stated in the question occurs as follows;

2 KI (aq) + 2 H2SO4 (aq) + MnO2 (s) → MnSO4 (aq) + K2SO4 (aq) + I2 (s) + 2 H2O (l)

The reaction here is the formation of iodine from MnO2 and KI in the presence of dropwise H2SO4.

Hypo is the common name of sodium thio-sulphate or sodium hypo-sulfite.

The equation of the titration reaction is;

2Na2S2O3 + I2→ Na2S4O6 + 2NaI

When this reaction takes place, iodine is decolorized due to its reduction to I^-.
