How many moles of P4 would you need to produce 34 g of PH3?

Chemistry

Molecular weight of P (Phosphorous) = 30.97g/mol

Hydrogen is just 1 g/mol.

How many moles is 34g of PH3?

Get the weight of PH3 (30.97 + (3X1)) = 33.97g/mol

So 34g/33.97g/mol = 1.0009 moles.

I bet for this problem it's easier to round this to 1.

If you look at just the moles in the equation:

P4(s) + 6 H2(g) → 4 PH3(g)

OR

1 + 6 → 4

If 1 (P4) gives us 4 (PH3), what gives us 1 (PH3)?

1/4 = x/1

solve for x

An example of a general formula of an acid is
<span>HCl

This is called as hydrochloric acid or hydrogen chloride.

H represents for the atom of Hydrogen
and Cl represents for the atom of Chlorine

Since their charges are -1, and +1, it's ratio is 1:1</span>

Using the electronegativity values in the chart below, which bond is the most polar?
lorasvet [3.4K]

Answer:

C-O

Explanation:

you have to check the all four bonds and find out their electronegativity difference. Whichever has the largest difference, is your answer.

  1. N-O = 3.04 - 3.44 = -0.4
  2. Cl-Cl = 3.16 -3.16 = 0
  3. C-O = 3.44 -  2.55 = 0.89
  4. C-H = 2.55 - 2.20= 0.35

Now check the differences, the largest electronegativity differences means the most polar bond
