What is the oxidation number of chromium in the ionic compound ammonium dichromate (nh4)2cr2o7?
lesya692 [45]
The oxidation number of an element is the number of electrons that are gained or lost by the element to form a chemical bond. 
the net oxidation number of the ion is its charge.
compound (NH₄)₂Cr₂O₇ is made of cation - NH₄⁺ and anion - Cr₂O₇²⁻
oxidation number of ion - -2
(oxidation number of Cr x 2 Cr atoms) +(oxidation number of O x 7 O atoms )= -2
oxidation number of Cr = y
oxidation number of O = -2
(y x 2) + (-2 x 7) = -2
2y - 14 = -2
2y = 12
y  = + 6
therefore oxidation number of Cr is +6

viktelen [127]

Answer:

4.858 g

Explanation:

Start with the formula

density = \frac{mass}{volume}

density = 1.98 g/mL

volume = 2.45 mL

mass = ??

rearrange the formula to solve for mass

(density) x (volume) = mass

Add in the substitutes and solve for mass

1.98 g/mL x 2.45 mL = 4.858 g

How do u get the formulae for sodium oxide​
Maslowich

Answer:

The Chemical formula of sodium is Na.

The Chemical formula of oxide is O.

Explanation:

Therefore we know that the term 'valency' is called as the combining capacity of an atom of an element.

So by taking the valency of Sodium and  Oxide, we get  

Sodium with valency '1' and Oxide with valency '2'.

Na         O

1             2

When you cross over you get 'Na2O' as the formula for sodium oxide.

Hope this is helpful for you!

Don't forget to rate or give brainliest answer.!!

TY.
