Molal concentration gives the number of moles dissolved in 1 kg of solution.
Molal concentration of H₂SO₄ is 2.88 mol/kg
the weight of H₂SO₄ in 1 kg - 2.88 mol x 98 g/mol = 282.2 g
The total weight of solution - 1000 g + 282.2 g = 1282.2 g
density of solution is 1.167 g/ml
We need to find how many moles are dissolved in 1 L.
We know the weight of the solution, using this we can calculate volume of the solution
volume of solution is - 1282.2 g / 1.167 g/mL = 1098.7 mL
The number of H₂SO₄ moles in 1.0987 L = 2.88 mol
Therefore in 1 L = 2.88 mol / 1.0987 L = 2.62 mol
Molarity of H₂SO₄ is 2.62 mol/L = 2.62 M
Besides nylon, HCl is formed from the reaction of adipoyl chloride and 1,6- diaminohexane , but HCl is the byproduct molecule.
<h3>What is formed when adipoyl chloride and 1,6-diaminohexane reacts with each other and what are the by products?</h3>
- Adipoyl chloride is the monomer and hexamethylinediamine is also the monomer which reacts together to form polymer.
- The polymer formed is named nylon6,6 which is a co polymer and nylon 6,6 find its use in various other activities of life.
- Nylon6,6 is a copolymer since the participation of two monomers , and not a single monomer undergoing decomposition.
- Nylon6,6 is formed with an elimination of small molecule of HCl which is considered to be a by product .
- It is formed by a condensation reaction and hence HCl is the product formed from the reaction of adipoyl chloride and 1,6- diaminohexane.

Answer:
Protons, neutrons, and electrons
Explanation:
Both protons and neutrons have a mass of 1 amu and are found in the nucleus. However, protons have a charge of +1, and neutrons are uncharged. Electrons have a mass of approximately 0 amu, orbit the nucleus, and have a charge of -1.
B is correct because it doesn't depend on the movement just how the partials move at boiling point, ie it will expand but not gain motion
