Nitrogen dioxide and water react to produce nitric acid, hno3, and nitrogen oxide.

3no2 + h2o --> 2hno3 + no

how many grams of no are produced from 15.8 g of h2o?

26.3 grams of NO are produced

Explanation:

3NO₂ + H₂O → 2HNO₃ + NO

In this reaction 1 mol of water is needed to produce 1 mol of NO

Ratio is 1:1

15.8 g / 18 g = 0.877 mol of water

0.877 mol of water will produce 0.877 mol of NO

Molar mass NO = 30 g/m

0.877 moles . 30 g/m = 26.3 g

26.33g of NO will be produced

Explanation:

3NO2 + H2O --> 2HNO3 + NO

RMM of NO = 14 +16 =30g/mol

RMM of H2O = (2x1) + 16 = 2 +16 = 18g/mol

From the equation,

18g of H2O produced 30g of NO.

Therefore, 15.8g of H2O will produce Xg of NO i.e

Xg = (15.8 x 30)/18 = 26.33g

15.8g of H2O will produce 26.33g of NO.

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
