calculate the ph of the resulting solution if 17.0 ml of 0.170 m hcl(aq) is added to 22.0 ml of 0.170 m naoh(aq).
Natalka [10]

The pH of the finsl solution is equal to <u>2.93</u>

Concentration is the abundance of a constituent divided by way of the overall volume of an aggregate. several sorts of mathematical descriptions may be outstanding: mass concentration, molar concentration, variety concentration, and extent awareness.

C₁ = 0.170 m

V₁ = 17 ml = 0.017 L

C₂ = 0.170 M

V₂ = 22 ml = 0.022 L

C₁V₁ =C₂V₂

0.170× 0.017 L = 2.89 × 10⁻³  ------------- HCl

0.170× 0.022 L = 3.74 × 10⁻³  ------------ NaOH

⇒ 3.74 × 10⁻³  -  2.89 × 10⁻³ = 0.85 × 10⁻³

⇒ 3 + log 0.85

⇒ 3 + -0.07

⇒ pH = <u>2.93</u>

The concentration of an solution is a degree of the amount of solute that has been dissolved in a given amount of solvent or solution. A focused solution is one which has a rather huge amount of dissolved solute.

Dafna1 [17]

Answer:

The answer would be A. the number of electrons in the outermost electron shell.

Explanation:

These are called valence electrons which are transferred, shared, and rearranged by creating covalent bonds producing new substances.

Hope this helped! :)

A warehouse has 5,000 drums of liquid chemicals. The foreman knows that 50 of these drums contain off-quality chemicals. Assume
IrinaVladis [17]
Given that the drum is replaced each time before sampling, the selections are independent events. Then, the probability of the combined event is the product of each probability: (50/5000) * (50/5000) * (50/5000) = (1/100)^3 = 0.000001
