Liquid hexane, C6H14, burns in oxygen gas to yield carbon dioxide and water. What is the minimum mass of oxygen required for the
Usimov [2.4K]

Answer: 46.6 grams

Explanation:

2C_6H_{14}+19O_2\rightarrow 12CO_2+14H_2O

Given : density of hexane = 0.660 g/ml

volume of hexane = 20 ml

Mass of hexane = {\text {density of hexane}}\times {\text {volume of hexane}}=0.660g/ml\times 20ml=13.2g

moles of hexane =\frac{\text {given mass}}\times {\text {molar mass}}=\frac{13.2g}{86.18g/mol}=0.15moles

According to stoichiometry :

2 moles of hexane reacts with 19 moles of oxygen

Thus 0.14 moles hexane will react with =\frac{19}{2}\times 0.15=1.45 moles of oxygen

Mass of oxygen =moles\times {\text {molar mass}}=1.45\times 32=46.6g

Thus minimum mass of oxygen required for the complete reaction of 20.0 mL of hexane is 46.6 grams.

!: (a) 20 cm: 80
RoseWind [281]

Answer:

THE LENGTH OF THE AIR COLUMN IS 9.5 CM

Explanation:

Taking the atmospheric pressure to be 760 mmHg;

When the capillary tube is held horizontally, the pressure of the tube is 760 mmHg

when the capillary tube is held vertically, the pressure increases by 4 cm = 40 mm

The new pressure of the tube is hence, 760 + 40 mmHg = 800 mmHg

Using the pressure forlmula;

P1 V1 = P2 V2

P1 A1 L1 = P2 A2 L2

where A1 and A2 is the area of the capillary tube and it is equal, it cancels out.

P1 l1 = P2 l2

l2 = P1 l1 / P2

l2 = 760 * 10 / 800

l2 = 9.5 cm

The length of the air in the tube is 9.5 cm.
