assuming the fluid has a density of 1.00 g/cm3 , at what height h should the bottle be placed so the liquid pressure is 70 mm - hg ?

166.87 g of aluminum chloride are created when 34 g of aluminum and 39 g of chlorine gas are combined.

One mole of aluminum and three moles of chlorine combine to generate the ionic compound aluminum chloride.

Al + 3Cl → AlCl3

This reaction results in the formation of AlCl3 from one mole of Al and three moles of Cl. Here, Al serves as the limiting reactant. So the product's mass is solely dependent on Al.

Al has an atomic mass of 27 g/mol.

133.5 g/mol for AlCl3.

Al has a given mass of 34 g. Therefore, there are 1.25 moles instead of 34 moles because of the ratio of 27 to 34.

Thus, 1.25 moles of aluminum produce 1.25 moles of aluminum chloride from 1 mole of aluminum.

1.25 mole of AlCl3 weighs 1.25 mol and 133.5 g/mol =  166.87 g.

As a result, the reaction produced 166.87 g of AlCl3.

Considering the Dalton's partial pressure, the mole fraction of CO₂ in the sample is 0.326.

The pressure exerted by a particular gas in a mixture is known as its partial pressure.

Dalton's partial pressure law can be expressed in terms of the mole fraction of the gas in the mixture. The mole fraction is a dimensionless quantity that expresses the ratio of the number of moles of a component to the number of moles of all the components present.

In a mixture of two or more gases, the partial pressure of gas A can be expressed as:

[tex]P_{A}[/tex]=[tex]x_{A}[/tex][tex]P_{T}[/tex]

In this case, you know:

So, the mole fraction of CO₂ in the sample is calculated as:

Potassium chloride is dissolved in an aqueous solution of silver nitrate. The final molarity of the chloride anion in the solution is 2.824 M.

Let's take 2.04 g of potassium chloride which is dissolved in 150 ml of a 0.20 M aqueous solution of silver nitrate.

The balanced equation of this problem is going to be -

KCL + AgNO₃ ⇒ KNO₃ + AgCL

Moles present in the KCL = 2.04 g

No. of moles =  [tex]\frac{Mass}{Molar Mass}[/tex]

= [tex]\frac{2.04}{74.5513}[/tex]

= 0.02736 moles

Moles of Silver Nitrate = molarity × Volume in L

= 0.20 × 0.150

= 0.030 moles of silver nitrate

Therefore, silver nitrate is the limiting agent.

Now, we will calculate the moles of the chloride anion -

= 0.030 moles × [tex]\frac{1 mole potassium chloride}{2 moles of silver nitrate }[/tex]

= 0.015 moles of potassium chloride

Remaining moles = 0.02736 moles - 0.015 moles

= 0.01236 moles of potassium chloride

Or we can say 0.04236 moles of the chloride anion.

Now, we calculate the molarity = [tex]\frac{No. of moles}{Volume in L}[/tex]

Sodium has a single valence electron in its outer shell, which means that it is highly reactive and tends to form positive ions by losing this electron in chemical reactions. Chlorine, on the other hand, has seven valence electrons in its outer shell and tends to form negative ions by gaining an extra electron in chemical reactions.

When sodium and chlorine react, they transfer an electron from the outer shell of sodium to the outer shell of chlorine. This transfer leads to the formation of sodium chloride, which is a stable compound that is commonly known as table salt.
