The vapor pressure of dichloromethane, CH2Cl2, at 0 ∘C is 134 mmHg. The normal boiling point of dichloromethane is 40. ∘C. How w
Elden [556K]

Answer:

The molar heat of vaporization of dichloromethane is 30.8kJ/mole

Explanation:

Using Clausius Clapeyron equation

ln (P1/P2) = (ΔHvap/R) (1/T2-1/T1)

At initial temperature of Ooc , the vapour pressure is 134mmHg

Therefore T1 = 0+273 =273K

And P1 = 134mmHg

At normal boiling point of 40oC , the vapour pressure is 760mmhg

T2 = 40 +273 = 313K

P2 = 760mmHg

ln (134/760) = ΔHvap/(8.3145 J/molK)

( 1/313K - 1/273K)

ΔHvap = 30800J/mol

= 30.8kJ/mol

Therefore, the molar heat of vaporization can be calculated using

Clausius Clapeyron equation using the above steps

For the following reaction, 41.0 grams of sulfuric acid are allowed to react with 36.5 grams of zinc hydroxide. What is the maxi
Ilya [14]

The FORMULA for the limiting reagent is ZnOH_2.

4.27 grams of reactant remains after the reaction is complete.

<h3>What is a limiting reagent?</h3>

The limiting reagent is the reactant that is completely used up in a reaction and thus determines when the reaction stops.

Given data:

Mass of sulfuric acid = 41.0 grams

Molar mass of sulfuric acid = 98.08 g/mol

Mass of zinc hydroxide = 36.5 grams

Molar mass of zinc hydroxide = 99.424 g/mol

Step 1:moles sulfuric acid = mass sulfuric acid / molar mass sulfuric acid

moles sulfuric acid = 41.0 grams / 98.08 g/mol

moles sulfuric acid = 0.41 moles

Step 2: moles of zinc hydroxide

moles zinc hydroxide = 36.5 grams / 99.424 g/mol

moles zinc hydroxide =0.367 moles

Step 3: Calculate limiting reactant

zinc hydroxide is the limiting reactant. It will completely be consumed.

There will remain 0.41 moles - 0.367 moles = 0.043 moles

This is 0.043 moles x 99.424 g/mol

= 4.27 grams
