Ionic compounds are composed of a non-metal as the anion and a metal as the cation. Covalent compounds on the other hand are composed of both non-metals from both charges. In this case, OF2 is covalent, PBr3 is covalent, SeO2 is ionic, C5H12 is covalent, and CBr4 is covalent.
Answer is the ideal gas law
The half life of strontium 90 is 28.8 years
The molecular weight of LiOH would be 23.95 g/mol, so the amount of LiOH in mol would be: 1.64g/(<span>23.95 g/mol)= 0.069 mol
The reaction of LiOH with HCl would be:
</span><span>HCl + LiOH = H2O + LiCl
The coefficient of LiOH:HCL is 1:1 so you need the same amount of HCl to neutralize LiOH.
HCl= LiOH
volume* 0.15M= </span>0.069 mol
volume= 0.069 mol/ (0.15 mol/ 1000ml)
volume= 459.29 ml
Answer:
Solution:-
The gas is in the standard temperature and pressure condition i.e. at S.T.P

As given that the expansion is isothermal and reversible
∴ΔU=0
Now from first law of thermodynamics,
ΔU=q+w
∵ΔU=0
∴q=–w
Given that the heat is absorbed.
∴q=1000cal
⇒w=−q=−1000cal
Now,
Work done in a reversible isothermal expansion is given by-
w=−nRTln(
