A. would be H20 because O is 2- and H is 1+ so it needs to balance to 0.
sorry I don't know the others but I hope this helps with letter A

A sample of vinegar has a hydronium concentration of 1.6 × 10-3 M. What is the pH of the vinegar?
loris [4]
PH is defined as the negative log of Hydronium Ion concentration.

So, in order to find the pH of vinegar, we find the negative log of its hydronium ion concentration.

pH=-log[ H_{3}O^{+}] \\  \\ 
pH=-log(1.6  * 10^{-3})  \\  \\ 
pH=2.8

So, the pH of given vinegar solution will be 2.8.

Therefore, the answer to this question is option B

Silver sulfate (Ag2SO4) is slightly soluble in water and it partly dissolves at the equilibrium according to the following balan
natka813 [3]

Answer:

a) S = 0.0152 mol/L

b) S' = 4.734 g/L

Explanation:

  • Ag2SO4 ↔ 2Ag+  +  SO42-

           S                2S            S...............in the equilibrium

  • Ksp = 1.4 E-5 = [ Ag+ ]² * [ SO42-]

a) molar solubility:

⇒ Ksp = ( 2S) ² * S = 1.4 E-5

⇒ 4S² * S = 1.4 E-5

⇒ S = ∛ ( 1.4 E-5 / 4 )

⇒ S = 0.0152 mol/L

b) solubility ( S' ) in grams per liter:

∴ Mw Ag2SO4 = 311.799 g/mol

⇒ S' = 0.0152 mol/L * ( 311.799 g/mol )

⇒ S' = 4.734 g/L

What does the period number tell about the energy levels occupied bye electrons in an atom
anyanavicka [17]

Answer:

The period number tells which is the highest energy level occupied by the electrons.

Explanation:

  1. The period number (denoted by n) is the outer energy level that is occupied by electrons in an atom.
  2. The period number that an element is in, is the number of energy levels that the element has.
  3. When we move across a period from left to right in a periodic table the number of electrons in atoms increases within the same orbit.
