That experiment it's called a MRE bomb. That's why when you add the water to the chemicals in the bottle, it heats up causing the gasses to expand and then the bottle explodes. (It is a very dangerous experiment)
Hope I helped!

El teorema de Pitágoras se generaliza a espacios de dimensiones superiores. Algunas de las generalizaciones están lejos de ser obvias. El teorema de Pitágoras sirve como base de la fórmula de distancia euclidiana.

298 g of calcium carbonate CaCO₃
Explanation:
We have the following chemical reaction:
CaCN₂ (s) + 3 H₂O (l) → CaCO₃ (s)+ 2 NH₃ (g)
number of moles = mass / molar weight
number of moles of H₂O = 161 / 18 = 8.94 moles
Knowing the chemical reaction we devise the following reasoning:
if 3 moles of H₂O produces 1 mole of CaCO₃
then 8.94 moles of H₂O produces X moles of CaCO₃
X = (8.94 × 1) / 3 = 2.98 moles of CaCO₃
mass = number of moles × molar weight
mass of CaCO₃ = 2.98 × 100 = 298 g
