Answer:

The metal buckle conducts heat away from the hand than both the steering wheel and center console.

Explanation:

Good conductors are materials that allow both heat and electricity to flow easily through them. Examples of good conductors are metals.

Poor conductors or insulators are materials which do not allow both heat and electricity to flow easily through them. Examples of insulators are most non-metals, plastics, rubber, wool, wood, etc.

On a cool day a metallic object like the buckle of a car's seatbelt will easily conduct heat away from the hand than other materials inside the car like the seat, the seatbelt, the steering wheel and the centre console as these materials are made from insulators or poor conductors.

Therefore, the metal buckle will feel colder to touch than other things in the car because it conducts heat away from the hand than both the steering wheel and center console.

The molarity of the solution, which contains 58.5 g of NaCl dissolved in 0.25 L of solution, is approximately 4.004 M.

To calculate the molarity of a solution, we need to determine the number of moles of solute (NaCl) and then divide it by the volume of the solution in liters.

Given:

Mass of NaCl = 58.5 g

Volume of solution = 0.25 L

Step 1: Calculate the number of moles of NaCl.

To find the number of moles, we need to divide the mass of NaCl by its molar mass. The molar mass of NaCl is the sum of the atomic masses of sodium (Na) and chlorine (Cl).

Molar mass of NaCl = 22.99 g/mol (Na) + 35.45 g/mol (Cl) = 58.44 g/mol

Moles of NaCl = Mass of NaCl / Molar mass of NaCl

= 58.5 g / 58.44 g/mol

≈ 1.001 mol

Step 2: Calculate the molarity.

Molarity (M) is defined as moles of solute per liter of solution.

Molarity = Moles of solute / Volume of solution

= 1.001 mol / 0.25 L

≈ 4.004 M

Therefore, the molarity of the solution, which contains 58.5 g of NaCl dissolved in 0.25 L of solution, is approximately 4.004 M.

Answer:

343g H2SO4

Explanation

1. H2SO4 is the solute

2. Water is the solvent

3. Molarity = moles of solute / liter of solution = n / V

(Note the case of the letters is important in science. N stands for Normal in chemistry a type of concentration, n stands for the number of moles)

Rearrange the formula to find n

n = M x V

Here are the known values,

M = 3.5M

n = x mol

V = 1.00L

Plug it in and solve for n (the number of moles of H2SO4 in the solution)

n = 3.5M x 1.00 L = 3.50 mol of H2SO4

Molecular mass of H2SO4 is 1g/mole H x 2 + 32.1g/mol S + 16g/mol O x 4 = 98.1g/mol H2SO4

mass = number of mole x relative molecular mass

mass = n x 98.1g/mol

mass = 98.1g/mol H2SO4 x 3.50mol H2SO4

= 343g H2SO4 <-answer

The mass of H2SO4 needed to make a 3.50M solution that has a volume of 1.00L is 343grams.

The mass of a substance can be calculated by multiplying the number of moles of the substance by its molar mass.

However, the number of moles of the substance must first be calculated as follows:

Molarity = no of moles/volume

3.5M = n/1L

n = 3.5moles

molar mass of H2SO4 = 98g/mol

mass of H2SO4 = 98 × 3.5

mass of H2SO4 = 343g

Therefore, the mass of H2SO4 needed to make a 3.50M solution that has a volume of 1.00L is 343grams.

The molecular formula for the compound is 3 times the empirical formula NO₂, which gives us N₃O₆.

6. In the molecular formula for a compound with an empirical formula of NO₂ and a molar mass of 138.015 g/mol,

The empirical formula tells us the simplest whole-number ratio of atoms in the compound, which in this case is NO₂. The molar mass of the empirical formula NO₂ can be calculated by adding the atomic masses of nitrogen (N) and two oxygen (O) atoms:

Molar mass of NO₂ = (1 × atomic mass of N) + (2 × atomic mass of O)

Molar mass of NO₂ = (1 × 14.01 g/mol) + (2 × 16.00 g/mol)

Molar mass of NO₂ = 46.01 g/mol

Molecular formula units = Molar mass of the compound / Molar mass of the empirical formula

Molecular formula units = 138.015 g/mol / 46.01 g/mol

Molecular formula units ≈ 3

7. a. To determine the empirical formula of nicotine given the mass percentages of carbon (C), hydrogen (H), and nitrogen (N), we can assume a 100 g sample of nicotine.

Mass of C in 100 g of nicotine = 74.1 g

Mass of H in 100 g of nicotine = 8.6 g

Mass of N in 100 g of nicotine = 17.3 g

To find the moles of each element, divide the mass by their respective atomic masses:

Moles of C = 74.1 g / atomic mass of C ≈ 74.1 g / 12.01 g/mol ≈ 6.17 mol

Moles of H = 8.6 g / atomic mass of H ≈ 8.6 g / 1.008 g/mol ≈ 8.53 mol

Moles of N = 17.3 g / atomic mass of N ≈ 17.3 g / 14.01 g/mol ≈ 1.23 mol

To obtain the simplest ratio between the elements,  divide the number of moles by the smallest number of moles, which in this case is 1.23 mol:

C ≈ 6.17 mol / 1.23 mol ≈ 5

H ≈ 8.53 mol / 1.23 mol ≈ 7

N ≈ 1.23 mol / 1.23 mol ≈ 1

Therefore, the empirical formula of nicotine is C₅H₇N.

b. To determine the molecular formula of nicotine, its molar mass, which is given as approximately 160 g/mol.

The empirical formula of nicotine is C₅H₇N, with a molar mass of:

(5 × atomic mass of C) + (7 × atomic mass of H) + (1 × atomic mass of N)

(5 × 12.01 g/mol) + (7 × 1.008 g/mol) + (1 × 14.01 g/mol)

60.05 g/mol + 7.056 g/mol + 14.01 g/mol

≈ 81.116 g/mol

To find the molecular formula,  the molar mass of nicotine (160 g/mol) by the

Molecular formula ratio = 160 g/mol / 93.131 g/mol

≈ 1.717

Therefore, the molecular formula of nicotine is 2 times the empirical formula: C₁₀H₁₄N₂.

The mass of the asteroid is C. 1.2 x \(10^{12}\) Kg

To find the mass of the other asteroid, we can rearrange the equation for the gravitational force between two objects:

F = (G * m1 * m2) / \(r^{2}\)

where F is the force of gravity, G is the gravitational constant, m1 and m2 are the masses of the two asteroids, and r is the distance between them.

Given that the distance between the asteroids is 75000 m, the force of gravity between them is 1.14 N, and one asteroid has a mass of 8 x \(10^{7}\) kg, we can substitute these values into the equation and solve for the mass of the other asteroid (m2):

1.14 N = (6.67430 × \(10^{-11}\) N \(m^{2}\)/\(Kg^{2}\) * 8 x \(10^{7}\) kg * \(m2\)) / \((75000 m)^{2}\)
