What are the mol ratios? if you’re just comparing with the mass (which i doubt so since most limiting questions require u to compare the mols)
but if u are, the limiting would be nitrogen since it’s lesser than calcium mass
Answer:- The substance is Propane and right choice is C.
Solution:- 10140000 J of heat is used to boil 28.47 kg at 298 K. Here, the important thing is, the liquid is changing to vapor and the temperature is not changing means it's a phase change. So, the formula used for this is:
where, q is the heat energy, m is mass and is the enthalpy of vaporization.
Let's rearrange the formula for as:
=
Let's plug in the values:
=
=
If we round this then it is . Hence, the right choice is C. propane.

NOTE: that the electron-withdrawing groups decrease the electron density around the proton nucleus and therefore the nucleus feels the external magnetic field more. Hence, it requires a larger frequency to attain resonance(downfield).
Boyle's law
PV=const
P₁V₁=P₂V₂
V₂=P₁V₁/V₂
V₂=340.0kPa·250ml/50.0kPa=1700 ml = 1.7 l
