Answer:

Molarity of HCl  = 0.12 M

Explanation:

Given data:

Volume of HCl = 13.0 mL

Volume of NaOH = 36.11 mL

Molarity of NaOH = 0.045 M

Molarity of HCl = ?

Solution:

Formula:

M₁V₁   =   M₂V₂

M₁= Molarity of HCl

V₁ =  Volume of HCl

M₂ = Molarity of NaOH

V₂ = Volume of NaOH

M₁ × 13.0 mL =  0.045 M ×  36.11 mL

M₁  = 1.62 M.mL /  13.0 mL

M₁  =0.12 M

Which of the following pieces of laboratory glassware should be used to most accurately measure out a 25.00 ml sample of a solut
wel

Answer:

The correct answer is 25 mL graduated cylinder (it should be used in all the cases)

Explanation:

In order to measure 25.00 ml sample of a solution it should be used a 25 mL graduated cylinder, as it is previously and properly calibrated. The other laboratory glassware, beaker and erlenmeyer, have graduations which are approximate, so they are used when exact volumes are not needed.

ii) graduated cylinder has the least uncertainly. It is more accurate than a beaker or erlenmeyer (to within 1%)

iii) A 25 mL graduated cylinder should be used because it is the most accurate lab glassware (between those were mentioned: beaker, erlenmeyer).

Calculate the pH if the [H^+] = 9.71 ×<br> 10^-8
oksano4ka [1.4K]

Answer:

pH = 7.01

Explanation:

The pH can be calculated using the formula:

pH = -log[H⁺]

In this formula, [H⁺] represents the concentration of H⁺. Since you have been given this value, you can easily find the pH.

pH = -log[H⁺]

pH = -log[9.71 x 10⁻⁸]

pH = 7.01

What types of reactions are these 3 chemical equations?-
IceJOKER [234]

Answer:

*2Kl+Pb(NO3)2=PbI2+2KNO3: double replacement.

*2Al+3CuSO4=Al2(SO4)3+3Cu: single replacement.

*C2H5OH+3O2=2CO2+3H2O: combustion.

Explanation:

Hello there!

In this case, according to the required, it turns out necessary for us to recall the five types of reactions, combination, decomposition, single and double replacement and combustion as shown on the attached figure.

In such a way, since the first reaction follows the pattern AB+CD-->AD+CB we infer it is double replacement; the second reaction follows the patter A+BC-->AC+B and therefore it is single replacement; and the last one follows the pattern of combustion reaction due to the presence of CO2 and H2O on the products side.

Regards!
