lara31 [8.8K]3 years ago
4 0

Answer:

5

Explanation:

Given parameters:

Hydrogen ion concentration  =  0.00001M

Unknown:

pH of the solution =?

Solution:

The pH is used to estimate the degree of acidity or alkalinity of a solution. To solve for pH of any solution, we use the expression below;

          pH  = -log [H⁺]

[H⁺] is the hydrogen ion concentration

        pH  = -log (1 x 10⁻⁵)

      pH = -(-5) = 5

  1. it was first scientific and systamatic study of different element.
  2. there were may gaps for in discovered elements.After their discovery the got their proper place in table.
  3. with the help of mendeleev periodic table , properties of several elements were studied correctly.

demerits of mendeleev periodic table

  1. it could not arrange hydrogen as it shows the property of both alkali and halogens.
  2. it could not arrange isotopes because they have different atomic weight but same atomic number.
  3. it could not arrange Lanthanides and Actinides.

Calculate the ratio of effusion rates of cl2 to f2 .
WINSTONCH [101]
<span>Answer: Graham's law of gaseous effusion states that the rate of effusion goes by the inverse root of the gas' molar mass. râšM = constant Therefore for two gases the ratio rates is given by: r1 / r2 = âš(M2 / M1) For Cl2 and F2: r(Cl2) / r(F2) = âš{(37.9968)/(70.906)} = 0.732 (to 3.s.f.)</span>

12. How much mass is in a 3.25-mole sample of NH 4 OH? A. 10.8 g B. 34.0 g C. 35.1 g D. 114 g
Galina-37 [17]

Answer:

D. 114 g

Explanation:

  • NH4OH molecular weight. Molar mass of NH4OH = 35.0458 g/mol This compound is also known as Ammonium Hydroxide.
  • Convert grams NH4OH to moles or moles NH4OH to grams. Molecular weight calculation: 14.0067 + 1.00794*4 + 15.9994 + 1.00794.
