What is the oxidation number of phosphorus (P) in phosphoric acid (H3PO4)?
Sedaia [141]

Hey there!:

H is always +1 so the H's have a +3 charge.

O is always -2 so the O's have a -8 charge .

Now, suppose oxidation state for P = X , then :

+3  + X + (-8) = 0      (because of neutral molecule)

x = 8 - 3

x = + 5

So, X = +5 oxidation state.

Answer  C


Hope that helps!

If you have 2L of a solution with 6 moles of HCl in it, what is the molarity of it?
Vladimir [108]

Answer:

Molarity = 3 M

Explanation:

Given data:

Volume of solution = 2 L

Number of moles of HCl = 6 mol

Molarity = ?

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

by putting values,

Molarity = 6 mol / 2 L

Molarity = 3 M     (M = mol/L)

What is the final concentration if a 50.0 mL sample of a 15% H2SO4 solution is added to water to give a final volume of 250 mL?
Anna007 [38]

Answer:

The answer to your question is 3% H2SO4 solution

Explanation:

Data

Concentration 2 = C₂ = ?

Concentration 1 = C₁ = 15 %

Volume 1 = V₁ = 50 ml

Volume 2 = V₂ = 250 ml

Formula

             C₁V₁  = C₂V₂

Solve for C₂

             C₂ = C₁V₁ / V₂

Substitution

             C₂ = (15)(50) / 250

Simplification and result

             C₂  = 3 %
