What is the term for the lumps that form when an acid is added to milk? suspension precipitate gas colloid
2 answers:
Answer: Option (b) is the correct answer.
Explanation:
A precipitate is a substance that is an insoluble solid formed which is formed from a liquid.
For example,
Here, is a precipitate formed from aqueous solutions of lead nitrate and sodium iodide.
A colloid is a substance in which microscopic particles are non-evenly dispersed in a dispersion medium. For example, milk is a colloid.
When particles of a solute in a solvent settle after some time due to their large size then this solution is known as suspension.
A gas is a matter in which particles have high kinetic energy and they are held by weak Vander waal forces.
Therefore, we can conclude that the term for the lumps that form when an acid is added to milk is called as precipitate.

Answer: The mole ratio of sodium to sodium chloride 2:2.
Explanation:
As the given reaction equation is as follows.
Here, 2 moles of sodium reacts with 1 mole of and leads to the formation of 2 moles of NaCl.
This means that 2 moles of sodium gives 2 moles of NaCl on reaction with chlorine.
Hence, the ratio of moles of sodium to sodium chloride is 2:2.
Thus, we can conclude that the mole ratio of sodium to sodium chloride 2:2.
