Answer:- Melting point of [tex[CCl_4[/tex] is higher than
where as the vapor pressure of
.
Explanations:- Since both the molecules are non polar, the forces of attraction for carbon tetrachloride are comparatively stronger as it's a bigger molecule. We know that, stronger are the forces of attraction, higher is the melting point as more heat is required to break the bonds.
Stronger are the forces of attraction, lower is the vapor pressure as the molecules are more tightly bonded and less molecules goes to the gas phase.
So, melting point of carbon tetrachloride is higher but it's vapor pressure is lower as compared to carbon disulfide.
we are given the reaction Cu + 2AgNO3 ---> Cu(NO3)2 + 2Ag. This means for every mole Cu used, there are 2 moles of Ag produced. In this case, given 31.75 g Cu, converting to moles through molar mass and using stoichiometric ratio and the molar mass of Ag, the mass Ag produced is 107.9 grams.
