A homogeneous mixture has the same uniform appearance and composition throughout. Many homogeneous mixtures are commonly referred to as solutions. A heterogeneous mixture consists of visibly different substances.
Answer:
C.) 3.5 atm
Explanation:
Because you are dealing with pressure and volume, you can use Boyle's Law to help you find the missing variable. The general formula looks like this:
P₁V₁ = P₂V₂
In this formula, "P₁" and "V₁" represent the pressure and volume of the chamber originally. "P₂" and "V₂" represent the final pressure and volume. You have been given the values of all the other variables but "P₂". Therefore, you can plug these values into the formula and simplify to find the final pressure.
P₁ = 1.5 atm
V₁ = 1.4 L
P₂ = ?
V₂ = 0.60 L
P₁V₁ = P₂V₂ <---- Boyle's Law formula
(1.5 atm)(1.4 L) = P₂(0.60 L) <---- Plug in values
2.1 = P₂(0.60 L) <---- Multiply 1.5 and 1.4
3.5 = P₂ <----- Divide both sides by 0.60

Answer:
The answer to your question is: HCl = 58.44 g
Explanation:
To solve this problem, we must remember the law of conservation of mass that says that, matter cannot be created or destroyed, only changes its form.
That means that, the mass of the reactants must be equal to the mass of the products.
Process
Sodium (Na) + Chlorine (Cl) ⇒ Sodium chloride (HCl)
22.99 g 35.45 g x
22.99 + 35.45 = HCl
HCl = 58.44 g
