<h2>Let us predict the gas and liquid products in option </h2>
Explanation:
option 1 : 2 upper H g upper O (s) right arrow 2 upper H g (l) plus upper O subscript 2 (g).
Chemical reaction
It is the reactants react to form products .
Chemical equation
It is the method of representing reaction in terms of moles , specifying states , symbols , molecular formulas etc .
This actually gives the complete info about the reaction .
In the above asked question or any other question we can specify the states by writting :
Solid as "S".
Liquid as "L"
Gas as (g).
Answer:
both are the types of mixture and both are impure substances that donot have fixed composition and the composition of constituents is not uniform
Answer is: the freezing point is 1.63°C and boiling point is 82.01°C.<span>.
1) n(</span><span>nonelectrolyte solute) = 0.656 mol.
</span>m(C₆H₆ - benzene) = 869 g ÷ 1000 g/kg.
m(C₆H₆) = 0.869 kg.<span>
b(solution) = n(</span>nonelectrolyte solute) ÷ m(C₆H₆).<span>
b(solution) = 0.656 mol ÷ 0.869 kg.
b(solution) = 0.754 mol/kg.
2) ΔT = Kf(benzene) · b(solution).
ΔT = 5.12°C/m · 0.754 m.
ΔT = 3.865°C.
Tf = 5.50°C - 3.865°C.
Tf = 1.63°C.
</span>
3) ΔTb = Kb(benzene) · b(solution).
ΔTb = 2.53°C/m · 0.754 m.
ΔTb = 1.91°C.
Tb = 80.1°C + 1.91°C.
Tb = 82.01°C.<span>
