i. The new concentration is 0.116 M

ii. The new concentration is 0.029 M

<h3>What is the concentration of the original hydrochloric acid acid?</h3>

The concentration of the original or stock hydrochloric acid is calculated as follows:

  • Molarity = Percentage concentration * Density * 1000/Molar mass * 100

Molarity of stock HCl = 36 * 1.18* 1000 /36.5 * 100

Molarity of stock HCl = 11.6 mol/dm

i. Using the dilution formula: M₁V₁ = M₂V₂

M₂ = M₁V₁ /V₂

M₂ = 11.6 * 10/1000

M₂ = 0.116 M

The new concentration = 0.116 M

ii. Using M₁V₁ = M₂V₂

M₂ = M₁V₁ /V₂

M₂ = 0.116 * 5/20

M₂ = 0.029 M

The new concentration = 0.029 M

In conclusion, the new concentrations are found using the dilution formula.

Explain why the following statements are true:
Luda [366]
1.Atoms combine to form molecules which in turn are what makes up matter.

2.Electrons carry negative charges and protons carry positive charges. While protons have far more mass the number of protons and electrons in a stable atom is the same. These charges cancel each other out. If there is an imbalanced then the atom is radioactive and decays until it reaches stability.

3.According to the kinetic theory of matter, "<span>All matter is made up of atoms and molecules that are constantly moving. When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases."</span>

How many liters of fluorine gas, at standard temperature and pressure, will react with 23.5 grams of potassium metal? Show all o
Sladkaya [172]

Potassium 23.5g/39.0983g/mol = 0.601mol

The Ratio of reactants is 2 to 1 so (0.601mol)/2 = 0.3005mol

Therefore 0.3005mol of F2 is needed to find liters use

formula V = nRT/P (V)Volume = 22.41L

(T)Temperature = 273K or 0.0 Celsius

(P)Pressure = 1.0atm

<span>(R)value is always .08206 with atm n = 0.3005moles (273)(.08206)(0.3005)/1 = V V = 6.7319 Liters</span>
