The solubilty of a gas is 1.6 g/l at 760 mmhg what is the solubility of the same gas at a pressure of 2.5 atm? assume temperatur

jok3333 [9.3K]

We are going to use Henry's law:

when C1/P1 = C2/P2

at a constant temperature.

and when the C1 and C2 are the concentration of the gases ( the solubility)

and P1 and P2 is the Pressure 1 and pressure 2

and when 760 mmHg = 1 atm

so, by substitution:

1.6 g/L / 1 atm = C2 /2.5 atm

∴C2 = 1.6g/L *2.5atm /1 atm

= 4 g/L

The student is now told that the four solids, in no particular order, are calcium bromide (CaBr2), sugar (C6H12O6), benzoic acid

nataly862011 [7]

<h2>Answer : The order of conductivity from most conductive to least is this - </h2><h2>Calcium bromide $(CaBr_{2})$ , Potsassium bromide (KBr), Benzoic acid $C_{6}H_{5}COOH$ and last is sugar.</h2><h3>Explanation : </h3>

When dissolved in water $(CaBr_{2})$ produces three ions namely; $Ca^{+2}$ and $2Br^{-}$ which acts as best conductor amongst the given choices.

Next is potassium bromide when dissolved in water generates only two ions which are $K^{+}$ and $Br^{-}$ and acts as an conductor.

Benzoic acid $C_{6}H_{5}COOH$ , is a weak acid and is slightly ionized so it acts as an weak conductor.

Sugar is a non ionized compound so it is anon conductor.

Natural gas or methane is a fossil fuel. In a plentiful supply of air, it burns to give carbon dioxide and water. Write a balanc

Alex17521 [72]

Answer:

$CH_4 + 2O_2 --> CO_2 + 2H_2O$

Explanation:

The chemical formula for methane is $CH_4$

The chemical formula for oxygen is $O_2$

The chemical formula for carbon dioxide is $CO_2$

The chemical formula for water is $H_2O$

Methane burns in oxygen to give carbon dioxide and water:

$CH_4 + O_2 --> CO_2 + H_2O$

The balanced equation that will ensure an equal number of each atom on the left and right-hand sides of the equation would be:

$CH_4 + 2O_2 --> CO_2 + 2H_2O$
