Answer:
the density of indium is 7.2 g/cm^3
Explanation:
The computation of the density of indium is shown below:
Given that
Mass = 16.6 g
Volume = 48.6 c,^3 - 46.3cm^3 = 2.3 cm^3
Based on the above information
As we know that
Density = mass ÷ volume
So,
= 16.6g ÷ 2.3 cm^3
= 7.2 g/cm^3
hence, the density of indium is 7.2 g/cm^3
We simply applied the above formula so that the correct value could come
And, the same is to be considered

Answer:
The average speed of molecule of oxygen is one-fourth of the speed of the hydrogen molecule.
Explanation:
The kinetic energy of gas molecule is given by following equation:
Since the temperature (T) is constant for both molecules. Therefore, there kinetic energies will also be the same. Therefore,
<u>The average speed of molecule of oxygen is one-fourth of the speed of the hydrogen molecule.</u>
The answer is Weathering since its nature breaking down the concrete.
