Filtration separates mixture which is not dissolved and also they need to have different size of particles. Distillation usually separates mixture which will be dissolved but has different boiling point.
The answer is B.
occur gradually over millions of years.
Answer:
A chemical change occurred and a gas was produced.
Step-by-step explanation:
If there is no chemical reaction, the <em>Law of Conservation of Mass</em> says that
Total mass = Mass 1 + Mass 2
However, if the two liquids react and give off a gas, then
Total mass = Mass 1 + Mass 2 + Mass of gas
You are not measuring the mass of the gas, so the mass of the liquids after mixing is less than it was before mixing.
For example, if Liquid 1 was a solution of HCl and Liquid 2 was a solution of Na₂CO₃, they would give off CO₂ on mixing. but you would not be measuring the mass of the CO₂.
Chemical reactions. The number of electrons in an atom's outermost valence shell governs its bonding behavior. Therefore, elements whose atoms can have the same number of valance electrons are grouped together in the periodic table of the elements.
