Ionization constant of water, Kw is the product of  [H₃O⁺] and [OH⁻].In the autoionization of water, proton is transferred from one water molecule to another to produce hydronium ion (H₃O⁺) and hydroxide ion (OH⁻).

The equilibrium expression for the reaction is Kw = [H₃O⁺][OH⁻], where Kw is the autoionization constant of water.

As, Kw = [H₃O⁺][OH⁻]

The number of phosphorus atoms in a 2.34 g sample of calcium phosphate is calculated via molar mass and Avogadro's number. Your estimate of 9.1 x 10^21 phosphorus atoms is very close to the actual atoms present.

To solve this inquiry, let's start by finding the molar mass of calcium phosphate (Ca3(PO4)2). The molar mass is calculated as follows: 3(40.08 g/mole for Ca) + 2(1.01 g/mole for H) + 2(15.999 g/mole for O) + 2(30.974 g/mole for P) = 310.18 g/mole.

Next, divide the mass of the sample by the molar mass of calcium phosphate to find number of moles: 2.34 g ÷ 310.18 g/mole = 0.00754 moles.

Remember that 1 mole of calcium phosphate contains 2 moles of phosphorus atoms. Therefore, the number of moles of phosphorus atoms is 2*0.00754 = 0.01508 moles.

Then, use Avogadro's number (6.02 x 1023 atoms/mole) to find the number of phosphorus atoms: 0.01508 moles * 6.02 x 1023 atoms/mole = 9.08 x 1021 atoms. Your estimate of 9.1 x 1021 phosphorus atoms is essentially correct!

The reaction of aluminum and hydrogen bromide will form 212.44 grams of aluminum bromide.

The chemical equation for the reaction between aluminum and hydrogen bromide is:

[tex]2 Al + 3 HBr[/tex] →[tex]Al_2Br_6[/tex]

From this equation, we can see that the reaction is a stoichiometric reaction, which means that the ratio of the reactants and products is fixed and is determined by the coefficients in the balanced equation.

If we have 121 grams of hydrogen bromide, the number of moles of hydrogen bromide can be calculated using the molar mass of hydrogen bromide ([tex]HBr[/tex]) which is approximately 80.9 g/mol. So:

121 g [tex]HBr[/tex] /  80.9 g/mol = 1.49 mol [tex]HBr[/tex]

Since the coefficient of hydrogen bromide in the balanced equation is 3, we know that for every one mole of aluminum, we need 3 moles of HBr. So, in this case, we have excess [tex]Al[/tex], which means the limiting reactant is [tex]HBr[/tex], and we have 1.49 moles of [tex]HBr[/tex].

The number of moles of aluminum bromide ([tex]Al_2Br_6[/tex]) formed can be calculated by dividing the number of moles of [tex]HBr[/tex] by the coefficient of [tex]HBr[/tex] in the balanced equation, which is 3

1.49 moles [tex]HBr[/tex] / 3 = 0.497 moles [tex]Al_2Br_6[/tex]

We can calculate the number of grams of aluminum bromide by multiplying the number of moles by the molar mass of aluminum bromide, which is approximately 427.3 g/mol

0.497 moles [tex]Al_2Br_6[/tex]  * 427.3 g/mol = 212.44 g [tex]Al_2Br_6[/tex]

2.758 L Of liquid nitrogen are produced when gas is liquefied.

We are converting gaseous nitrogen to liquid nitrogen. Both of these substances have different densities. Therefore they will occupy different volumes . But they will have the same mass.

Step 1 : Find mass of nitrogen gas

So let us find out the mass of nitrogen gas occupied by 489 L .

The formula for density is, D = Mass / Volume

Density of nitrogen gas 4.566 g/L and the volume occupied by it is 489 L.

Let us plug in these values to find the mass of nitrogen gas.

The equation can be modified as follows.

Mass = Density × Volume

Mass = 4.566 / L × 489

Mass = 2232g

The mass of nitrogen gas is 2232 g.

Step 2 : Find the volume of a liquid nitrogen using the mass

The mass of a liquefied nitrogen is also the same.

Whereas, the density of liquid nitrogen is 809 g/L

Let us plug in this value of mass to find the volume of the liquid.
