Yes, higher the polarity and electronegativity of the nonhydrogen atom explain the trend in acid strength shown in model 3. It shows more attraction towards the H⁺ ions and lesser is the acidity.

An atom's propensity to draw electrons (or electron density) in its direction is measured by its electronegativity. It controls how the shared electrons between the two atoms in a bond are distributed. The greater an atom's electronegativity, the more strongly the electrons in its bonds are drawn to it.

Answer:

there are about 26.67 milligrams in 10 mL.

Explanation:

To find the number of milligrams in 10 mL, you can use the proportion:

(8 mg) / (3 mL) = (x mg) / (10 mL)

Where x is the number of milligrams in 10 mL. To solve for x, you can cross-multiply and divide:

(8 mg) * (10 mL) = (3 mL) * (x mg)

x = (8 mg) * (10 mL) / (3 mL)

x = 26.666.. mg

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]

So, the reaction of aluminum and hydrogen bromide will form 212.44 grams of aluminum bromide.

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.

Volume = 2232 / 809g / L
