Option "A" is the correct answer.

Texas produces more crude oil than any other state in the Union. Texas has 27 petroleum refineries with a total capacity of more than 5.1 million barrels of oil per day. Daily production of refined oil makes up 29% of the united State's refining capacity.

Texas and oil are synonymous. In 2006, the oil industry employed 3.1 percent of the state's workforce and produced $ 30.6 billion in earned income.

The oil drilled in Texas is used for everything from vehicle fuel to heating homes. Most of the oil in Texas is produced through drilling which differs from the tar-sand production of Alaska where the oil is closer to the surface.

What is the relationship between the number of carbon atoms in hydrocarbon at its boiling point ?

saveliy_v [14]

If no of carbon atoms be C
Boiling point of compound be BP

$\\ \tt\longmapsto C\propto BP$

No of carbon atoms is directly proportional to the boiling point of the compound.
If no of carbon atoms increases in a hydrocarbon the length of carbon chain also increases and all carbons get wrapped around themselves.
Which causes increase in boiling point of compound.

Look the table below for the boiling points of some alkanes

$\boxed{\begin{array}{c|c}\boxed{\bf Alkane}&\boxed{\bf Boiling point}\\ \sf CH_4&\sf -164°C \\ \sf C_2H_6 &\sf -88.6°C \\ \sf C_3H_8&\sf 42.1°C \\ \sf C_4H_{10} &\sf -0.5°C \\ \sf C_5H_{12} &\sf 36.1°C \\ \sf C_6H_{14} &\sf 68.9°C \\ \sf C_7H_{16} &\sf 98.4°C \\ \sf C_8H_{18} &\sf 125.7°C \\ \sf C_9H_{20} &\sf 150.4°C \\ \sf C_{10}H_{22} &\sf 150.7°C \end{array}}$

An electrolytic cell transferred 0.10 m o l of electrons when a constant current of 2.0 A was applied. How many hours did this t

marusya05 [52]

Answer:

1.34 hr

Explanation:

From the question given above, the following data were obtained:

Number of mole of electron (e) = 0.1 mole

Current (I) = 2 A

Time (t) =?

Next, we shall determine the quantity of electricity transferred. This can be obtained as follow:

1 mole of electron = 96500 C

Therefore,

0.1 mole of electron = 0.1 × 96500

0.1 mole of electron = 9650 C

Thus, 9650 C of electricity was transferred.

Next, we shall determine the time. This can be obtained as follow:

Current (I) = 2 A

Quantity of electricity (Q) = 9650 C

Time (t) =?

Q = It

9650 = 2 × t

Divide both side by 2

t = 9650 / 2

t = 4825 s

Finally, we shall convert 4825 s to hour. This can be obtained as follow:

3600 s = 1 hr

Therefore,

4825 s = 4825 s× 1 hr / 3600 s

4825 s = 1.34 hr

Thus, the time taken is 1.34 hr

Which statement is correct?Strong bases are good electrolytes because they completely ionize in water.Strong bases are poor elec

Andre45 [30]

Answer: Strong bases are good electrolytes because they completely ionize in water.

Explanation:

Weak bases are those substances which dissociate partially to give ions when dissolved in water.

$HCOOH\rightleftharpoons HCOO^-+H^+$

Strong bases are those substances which dissociate completely to give ions when dissolved in water.

$NaOH\rightarrow Na^++OH^-$

Strong bases are good electrolytes as they completely dissociate to give ions which help in the conduction of electrical current.
