Answer:
a. 4,00L
b. 16,00L
c. 12,31L
Explanation:
Avogadro's law says:
a. If initial conditions are 2,30mol and 8,00L and you lose one-half of atoms, that means you have 1,15mol:
<em>V₂ = 4,00L</em>
b. If initial conditions are 2,30mol and 8,00L and you add 2,30mol, that means you have 4,60mol:
<em>V₂ = 16,00L</em>
c. 25,0g of Ne are:
25,0g × (1mol / 20,1797g) = 1,24 moles of Ne. That means you have 2,30mol - 1,24mol = 3,54mol of Ne
<em>V₂ = 12,31L</em>
I hope it helps!
Answer:
The r.a.m. value is used to determine how many isotopes an element has.
Explanation:
Answer: The correct option is, They are different units of concentration.
Explanation: Molarity : It is defined as the number of moles of solute present in one liter of solution.
Answer:
The sum of the coefficients in the balanced equation is 11
Explanation:
A reaction where an organic compound reacts with oxygen to produce carbon dioxide and water is called combustion.
The balance reaction of combustion for methanol is:
2CH₃OH (l) + 3O₂(g) → 2CO₂(g) + 4H₂O (g)
Coefficients from stoichiometry are 2, 3, 2 and 4
Sum = 2 + 3 + 2 + 4 = 11
