3 0

The density is 4 g/cm³ or 4000 kg/m³.

Density = mass/volume = 12 g/3 cm³ = 4 g/cm³

The measurement of 4 g/cm³ is already in <em>SI units</em>.  

In SI <em>bas</em>e units,  

Density = (4 g/1 cm³) × (1 kg/1000 g) × (100 cm/1 m)³ = 4000 kg/m³

2N2 + 3H2 → 2NH3

There are two N≡N bonds and three H–H  bonds are in reactants.

Given:

The reaction between nitrogen gas and hydrogen gas.

2N_2+3H_2\rightarrow 2NH_3

To find:

Bonds on the reactant side

Solution:

2N_2+3H_2\rightarrow 2NH_3

Reactants in the reaction = N_2, H_2

The bond between nitrogen atoms in single N_2 molecule  = N≡N (triple bond)

Then in two N_2  molecules = 2 N≡N (triple bonds)

The bond between hydrogen atoms in single H_2 molecule = H-H (single bond)

Then in three H_2  molecules = 3  H-H (single bonds)

Product in the reaction =NH_3

The bonds between nitrogen and hydrogen atoms in single NH_3 molecule = 3 N-H (single bond)

Then in two NH_3  molecules = 6  N-H (single bonds)

So, there are two N≡N bonds and three H–H bonds are in reactants.
