Answer:
Ammonia is easily made in the laboratory by heating an ammonium salt, such as ammonium chloride NH4Cl with a strong alkali, such as sodium hydroxide or calcium hydroxide.
The gas may also be made by warming concentrated ammonium hydroxide.
Explanation:
2NH4Cl + Ca(OH)2 → CaCl2 + 2H2O + 2NH3(g)
During the early period of chemistry, the word caloric would refer to as a self-repellant fluid. It can be proved by the caloric theory. The caloric theory is an obsolete scientific theory that heat consists of a self-repellent fluid called caloric that flows from hotter bodies to colder bodies.
Answer:
4 g/cm³
Explanation:
Volume(V) = 60 cm³
mass (m) = 240 gm
density (d) = ?
We know density is defined as mass per unit volume so
d = m / v
= 240 / 60
= 4 g/cm³
