Answer:
The density of the sample is 36 g/cm³
Explanation:
m= 972g
l=3cm
V = l³ = 3³ = 27 cm³
density = mass/volume
= 972/27
= 36 g/cm³
Most reactions are exothemic. If the forward reaction of an equilibrium reaction is exothemic then the reverse reaction must be endothermic.
If a system in equilibrium is heated, it will move in exothermic direction to give out heat energy.
