Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Explanation:
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
For example:
If 10.0 g of calcium carbonate produced 3.8 g carbondioxide and 6.2 g calcium oxide than according to this law,
CaCO₃ = CaO + CO₂
10.0 g = 6.2 g + 3.8 g
10.0 g = 10.0 g
This reaction followed the law of conservation of mass.
The nitrogen cycle requires different types of bacteria.
The substance that gets dissolved is the solute and the substance that dissolves the solute is the solvent. Example: water is a solvent and salt is a solute
To obtain pure magnesium chloride, the following separation technique steps are employed:
- add water and filter to dissolve magnesium chloride
- evaporate the water in the filtrate and then crystallize obtain pure magnesium chloride
<h3>What are separation techniques?</h3>
Separation techniques are the techniques employed in the separation of the constituents of a mixture.
To obtain pure magnesium chloride from a mixture of magnesium chloride, magnesium, calcium carbonate, and powdered charcoal, the following steps are employed:
- add water and filter to dissolve magnesium chloride
- evaporate the water in the filtrate and then crystallize obtain pure magnesium chloride
In conclusion, separation techniques are used to separate the constituent of mixtures.

The aufbau principle, from the German Aufbauprinzip (building-up principle), also called the aufbau rule, states that in the ground state of an atom or ion, electrons fill atomic orbitals of the lowest available energy levels before occupying higher levels.
