It is due to strong ionic bonding between the anion and cation HCl, HF have low boiling point due to covalent bond between the elements if that answers the question if you were asking why.

What is the diffrence between speed and avarege speed

Gekata [30.6K]

Speed is actually instantaneous speed, the speed an object is moving at that very instant.
But average speed is the total distance traveled divided by the total time.
Let's say you travelled 10 miles in 2 hours, your average speed would be 10 divided by 2, which is 10 miles / hr.

But during those 10 miles you may be accelerating, decelerating and be travelling 1 mile/hour and 20 miles/hour at another point. But your average speed would be total distance / total time. So your instantaneous speed can change throughout that period of time.

On the basis of your knowledge of the reaction of halogens with alkanes, decide which product you would not expect to be formed

KIM [24]

Answer:

On the basis of your knowledge of the reaction of halogens with alkanes, decide which product you would not expect to be formed in even small quantities in the bromination of ethane?

A) BrCH2CH2Br

B) CH3CH2CH2Br

C) CH3CHBr2

D) CH3CH2CH2CH3

E) BrCH2CH2CH2CH2Br

Explanation:

The reaction of ethane with bromine in presence of UV light forms mono substituted ethane at all primary and secondary carbons.

This is an example of free radical substitution.

The structure of ethane and its bromination is shown below:

Among the given options that which is not possible to form is option B) that is CH3CH2CH2Br(propyl bromide).

Remaining all other products are possisble to form on free radical substitution of ethane.

typical room is 4.0 m long, 5.0 m wide, and 2.5 m high. What is the total mass of the oxygen in the room assuming that the gas i

andrey2020 [161]

Answer:

mass of oxygen gas in Kg = 15.0Kg

Explanation:

Volume of air in the room = 4.0m*5.0m*2.5m = 50m³

volume of oxygen in the room = 21/100 * 50m³ = 10.5m³

using the ideal gas equation; PV=nRT

number of moles of oxygen gas, n = PV/RT

At STP, P = 1atm, V = 10.5m³ = (10.5*1000)dm³ = 10500dm³, R = 0.082 atmdm³K⁻¹mol⁻¹, T = 273K

n = 1 * 10500/ (273 *0.082)

n = 469.04 moles

mass of oxygen gas in Kg = (no of moles * molar mass)/1000

molar mass of oxygen gas = 32g

mass of oxygen gas in Kg = (469.04 * 32)/1000

mass of oxygen gas in Kg = 15.0Kg
