Answer:
The law of constant composition says that the composition of a homogeneous mixture is always the same
Explanation:
The law of constant composition that is also known as Proust's Law says that when two substances react with each other, to form a compound they will always do in a constant weight ratio, that is, the ratio of the masses between two substances that form a compound, must be proportional.
Answer:
faster, and the ingredient will be a liquid.
Explanation:
Answer:
Strong Electrolyte
Explanation:
Electrolytes are classified into strong and weak electrolytes. Strong electrolytes are electrolytes that completely dissociate in an aqueous solution and are as well good conductors of electricity while weak electrolytes are those that are not completely dissociated in an aqueous solution and are not very good conductors of electricity.
Examples of strong electrolytes are strong acid, strong base, and salts. Examples of weak Electrolyte are weak acids and weak bases.
Thus the correct answer is strong electrolytes.
Answer:
The discovery of electron by j.j Thomson rejected the Dalton theory.
He stated that atom can be divided into its subatomic particles.
Explanation:
Dalton stated that atom is an indivisible particle. It can not be further subdivided.
The discovery of electron by j.j Thomson rejected the Dalton theory.
He stated that atom can be divided into its subatomic particles.
The electron is subatomic particle that revolve around outside the nucleus and has negligible mass. It has a negative charge.
Symbol= e-
Mass= 9.10938356×10-31 Kg
It was discovered by j. j. Thomson in 1897 during the study of cathode ray properties.
He constructed the glass tube and create vacuum in it. He applied electric current between electrodes. He noticed that a ray of particles coming from cathode to wards positively charged anode. This ray was cathode ray.
Properties of cathode ray:
The ray is travel in straight line.
The cathode ray is independent of composition of cathode.
When electric field is applied cathode ray is deflected towards the positively charged plate.
Hence it was consist of negatively charged particles.
