Answer:
As the specific heat capacity for pure diamond is 0.5091 and it is different from the specific heat capacity found that is 0.2699
, the diamond sample is not pure.
Explanation:
1. As the problem says the equation that describes the amount of heat gained or lost by a substance is:
q=Cp*m*ΔT
where q is the amount of heat, Cp is the specific heat capacity, m is the mass and ΔT is the change in the temperature.
2. Solving for specific heat capacity:
3. Replacing values:
As the specific heat capacity for pure diamond is 0.5091 and it is different from the specific heat capacity found that is 0.2699
, the diamond sample is not pure.
Answer: Option (d) is the correct answer.
Explanation:
When two atoms are bonded together then it is known as a diatomic molecule.
Such as nitrogen exists as molecule in atmosphere so, it is a diatomic molecule.
Hydrogen also exists as molecule in atmosphere so, it is also a diatomic molecule. Also, bromine is a diatomic molecule because it exists as
molecule into the atmosphere.
But helium exists as He molecule as it has 2 electrons so, as per the octet rule it's s-shell is completely filled. Hence, it is stable and exists as a monoatomic molecule into the atmosphere.
Thus, we can conclude that out of the given options, helium is not a diatomic molecule.
