The correct answer is making observations in his experiment.
In his cathode ray tube experiment J. J. Thomson proved that the cathode rays are indeed negatively charged particles. He then went on to calculate charge-to-mass ratio of the electron. J. J. Thomson’s pioneering work lest to the theory that the atomic structure is made up of charged particles.
The answer is Mixture. Two more substances put together but each retaining their own identity is a Mixture. They are t<span>wo or more substances dispersed in one another but each retaining their own identity.</span>
Answer:
Each element consists of indivisible, minute particles called atoms.
All atoms of a given element are identical.
Atoms of different elements have different masses.
Explanation:
Answer:
<u>A weak acid</u> is an acid which dissociates partially in a solution to release few hydrogen ions while <u>A strong acid</u> is an acid which completely dissociates in solution to release many hydrogen ions.
Answer:
Energy would be absorbed.
Explanation:
Lattice energy is defined as the energy required to break apart an ionic solid and convert its component atoms into gaseous ions. That is what you're doing in:
KCl (s) → K⁺(g) + Cl⁻(g)
The energy you require to obtain this reaction is 701 kJ/mol. As the value is positive, <em>energy would be absorbed.</em>
