Answer:

increasing pressure

Explanation:

According to Henry's Law the amount of gas that can be dissolved in liquid water increase with the increase in pressure.

Henry’s law is given by the following equation,

C = kP

where C is the concentration of the dissolved gas, k is a proportionality constant and P is the pressure of the gas.

Thus the solubility of the gas is directly proportional to the pressure of the gas.

Incresing Pressure will increases the amount of gas dissolved !!

so your answer is B !!

Extra : Cool example is Pepsi or coke !! CO2 is dissolved by high pressure

How many formula units of sodium chloride (NaCl) may theoretically be produced from 13.0 g FeCl3?

algol [13]

Answer:

$1.445\times 10^{23}$ formula units of sodium chloride can be formed from 13.0 gram of ferric chloride.

Explanation:

Mass of ferric chloride = 13.0 g

Moles of ferric chloride = $\frac{13.0 g}{162.5 g/mol}=0.08 mol$

1 mole of ferric chloride has three moles of chloride ions.Then 0.08 moles of ferric chloride will have :

$3\times 0.08 mol=0.24 mol$ of chloride

$Na^++Cl^-\rightarrow NaCl$

1 mole of sodium ion reacts with 1 mole of chloride ion to form 1 mole of NaCl. Then 0.24 moles of chloride ion will give:

$\frac{1}{1}\times 0.24 mol=0.24 mol$ of NaCl

1 mole = $N_A=6.022\times 10^{23}$ molecules/ atoms

Number of NaCl molecules in 0.24 moles :

$=6.022\times 10^{23}\times 0.24=1.445\times 10^{23} molecules$

$1.445\times 10^{23}$ formula units of sodium chloride can be formed from 13.0 gram of ferric chloride.

If a little old lady is doing 98.3 kilometers/hour, will she get a speeding ticket if the speed limit is 55 miles / hour? [USE:

shutvik [7]

Answer:

It is possible she could get one.

Explanation:

To solve this problem we need to convert 98.3 kilometers/hour to miles/hour.

In other words, we convert km to mi, to do so we multiply 98.3 km by a conversion factor, putting the unit we want to have in the numerator, and the unit we want to convert in the denominator:
