A student carried out a simple distillation on a compound known to boil at 124 oc and they reported a boiling point of 116-117 o
chubhunter [2.5K]

Answer :

The correct answer is due to incorrect position of thermometer .

Distillation  is process of separating two volatile liquids on the basis of their boiling points .In involves the following set up ( shown in image )

Since the Boiling point is found   is 116-117 C which is near to 124 C , also the purity was checked and thermometer was calibrated .

So the only error could be possible is position of thermometer .

The position of  bulb of thermometer is very important to get an accurate reading of boiling point .The vapor so formed should touch the side walls of bulb as soon as they are formed .

May be  the bulb of thermometer was   kept far from the vapors formed by liquid so,  s<u>ome of  the vapor before reaching to  bulb start condensing and their Temperature decreases </u>.  

Hence , the  temperature shown by thermometer was decrease than actual boiling point  due to incorrect position of thermometer.

Calculate the mass of ZnCl2 produced by the reaction of 49.8 grams of H2. Zn + 2HCl ZnCl2 + H2
tester [92]

Answer:

3300.85 g

Explanation:

Given data:

Mass of ZnCl₂ produced = ?

Mass of H₂ produced = 49.8 g

Solution:

Chemical equation:

Zn + 2HCl     →    ZnCl₂ + H₂

Number of moles of  H₂:

Number of moles = mass/molar mass

Number  of moles = 49.8 g/ 2.056 g/mol

Number  of moles = 24.22 mol

Now we will compare the moles of H₂ with ZnCl₂ form balance chemical equation.

                         H₂              :              ZnCl₂

                          1                :                   1

                        24.22         :              24.22

Mass of ZnCl₂:

Mass = number of moles × molar mass

Mass =  24.22 × 136.286 g/mol

Mass = 3300.85 g

Sodium metal reacts with water to produce hydrogen gas according to the following equation: 2Na(s) + 2H2O(l)2NaOH(aq) + H2(g) Th
Maru [420]

Answer:

Number of moles of sodium reacted = 0.707 moles

Explanation:

P(H₂) = P(T) – P(H₂O)

P(H₂) = 754 – 17.5 = 736.5 mm Hg

Use the ideal gas equation which

PV= nRT, where P is the pressure V is the volume, n is the number of moles R is the Gas Constant and T is temperature

<u>Re- arrange to calculate the number of moles and using the data provided</u>

n = P x V/R x T

n =736.5 x 8.77/62.36367 x (mmHg/mol K) x (20 + 273)

n = 0.35348668

n = 0.353 moles H₂

<u>from the equation we know that</u>

0.353 mole H₂ x 2mole Na/1mole H₂, So

0.353 x 2 = 0.707 mole Na

The number of moles of Sodium metal reacted were 0.707 moles.
