what happens when a gas obtained by heating Ammonium Chloride and slaked lime are passed through copper sulphate ?​
gogolik [260]

Answer:

Consequently, what happens when gas obtained by heating slaked lime and ammonium chloride is passed through copper sulphate solution? The HCl in the gas mixture will form hydrochloric and the H+ will react with some of the NH3(aq), forming NH4^+, and with some of the SO4^2-, forming HSO4^-.

2N2 + O2 -------> 2 N2O
notka56 [123]

Answer:

Explanation:

Given data:

Mass of N₂ = 48.7 g

Moles of N₂ = ?

Molecules of N₂ = ?

Mass of N₂O = ?

Moles of N₂O = ?

Atoms of N₂O = ?

Solution:

Chemical equation:

2N₂ + O₂  →  2N₂O

Number of moles of N₂:

Number of moles = mass/ molar mass

Number of moles = 48.7 g / 28 g/mol

Number of moles = 1.74 mol

Number of molecules of N₂:

1 mole = 6.022 × 10²³ molecules

1.74 mol×  6.022 × 10²³ molecules/1 mol

10.5  × 10²³ molecules

Now we will compare the moles of N₂ with N₂O from balance chemical equation:

                 N₂             :           N₂O

                  2             :             2

               1.74            :           1.74

Moles of N₂O:  

1.74 mol

Mass of N₂O:

Mass = number of moles × molar mass

Mass =  1.74 mol ×  44 g/mol

Mass = 76.56 g
