Using the balanced equation N2+O2=2NO, how many grams of NO can be produced when 25.0 grams of N react?

Oxana [17]

Answer:

$53.55gNO$

Explanation:

Hello there!

In this case, according to the given chemical reaction, it is possible for us to calculate the produced grams of nitrogen monoxide by starting with 25.0 g of nitrogen via their 1:2 mole ratio and the molar masses of 30.1 g/mol and 28.02 g/mol, respectively and by some stoichiometry:

$=25.0gN_2*\frac{1molN_2}{28.02gN_2}*\frac{2molNO}{1molN_2}*\frac{30.01 gNO}{1molNO}\\\\=53.55gNO$

a. A solution of potassium dichromate is reduced to chromium(III) ions by zinc metal in the presence of an acid causing the solu

asambeis [7]

Explanation:

It is known that molecular formula of potassium dichromate is $K_{2}Cr_{2}O_{7}$ . As potassium has an oxidation state of +1 and an oxygen atom has an oxidation state of -2.

Let the oxidation state of chromium is x. Therefore, calculate the oxidation state of chromium as follows.

$K_{2}Cr_{2}O_{7}$ = 0 (as the molecule is neutral)

$(2 \times 1) + 2x + (-2 \times 7)$ = 0

2 + 2x - 14 = 0

x = +6

Thus, we can conclude that the oxidation state of the chromium in the potassium dichromate molecule is +6.
