Calculate how many moles of no2 form when each of the following completely reacts. 2n2o5(g)→4no2(g)+o2(g) part a 1.0 mol n2o5 express your answer using two significant figures. nothing mol m o l request answer part b 5.4 mol n2o5 express your answer using two significant figures.

Part A: 2.0 mol.

Part B: 10.8 mol.

Explanation:

2N₂O₅(g) → 4NO₂(g) + O₂(g),

It is clear that 2 mol of N₂O₅(g) dissociate to 4 mol of NO₂(g) and 1 mol O₂(g).

Part A 1.0 mol N₂O₅:

Using cross multiplication:

2 mol of N₂O₅(g) produces → 4 mol of NO₂(g), from stichiometry.

1 mol of N₂O₅(g) produces → ??? mol of NO₂(g),

∴ The no. of moles of NO₂ produced = (1 mol)(4 mol)/(2 mol) = 2.0 mol.

Part B 5.4 mol N₂O₅:

Using cross multiplication:

2 mol of N₂O₅(g) produces → 4 mol of NO₂(g), from stichiometry.

5.4 mol of N₂O₅(g) produces → ??? mol of NO₂(g),

∴ The no. of moles of NO₂ produced = (5.4 mol)(4 mol)/(2 mol) = 10.8 mol.

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.

the answer would be b i believe
