Specific heat capacity (c) of a material is related to the Energy Absorbed (Q), mass of the material (m) and the change in temperature (T) by the following equation:
Substituting the values of Q, m and T in the above equation, we get:
So the specific heat capacity of the metal with given conditions will be 0.129 J/g.K
Substituting the values of Q, m and T in the above equation, we get:
So the specific heat capacity of the metal with given conditions will be 0.129 J/g.K
The absorption spectrum is the result of absorption of light radiation by a material (solid or liquid) as a function of wavelength or frequency. The figure is shown below:
Answer:
4 moles of and 1 mole of
will be present in the reaction vessel
Explanation:
The reaction given in the question is
⇒
According to the stoichiometric coefficients of the reaction, 2 moles of requires 3 moles of
so in this reaction,
is a limiting reagent. So we will consider that
is in excess.
Now,
Since 3 moles of requires 2 moles of
So, for 6 moles of the moles of
required =
= 4 moles.
Moles of remaining after the completion of reaction = 5 - 4 = 1 mole.
Again,
Since 3 moles of produces 2 moles of
So, moles of produced by 6 moles of
=
= 4 moles.
Therefore, after the completion of reaction, 4 moles of and 1 mole of
will be present in the reaction vessel.
