<span>The answer is synthesis. This is a kind of reaction in which numerous reactants mix to make a single product. Synthesis responses discharge energy in the way of heat and light, so they are exothermic. An instance of a synthesis reaction is the creation of water from hydrogen and oxygen.</span>
Answer:
P₂ = 3.86 atm .
Explanation:
We assume that during this change , the temperature of the gas remains constant .
So the gas will obey Boyle's law .
P₁ V₁ = P₂V₂
5.08 x 7.56 = P₂ x 9.94
P₂ = 3.86 atm .

i hope that i got it right im not very good with questions
Answer: Concentration of the chemist's sodium chloride solution is 34.4 mol/L.
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

where,
n= moles of solute
= volume of solution in ml
Given : moles of
= 6.89
volume of solution = 200 ml
Putting in the values we get:

Thus the concentration of the chemist's sodium chloride solution is 34.4 mol/L.
