Answer:
When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na+) and a chloride anion (Cl-), both ions have complete valence shells, and are energetically more stable. The reaction is extremely exothermic, producing a bright yellow light and a great deal of heat energy.
Cathode rays are made up of negatively charged particles.
Atoms contain negatively charged particles.
Explanation:
The experiment carried out by J.J Thomson provided evidence to support that fact that atoms contains negatively charged particles and that cathode rays are negatively charged.
J.J Thomson performed experiments using a gas discharge tube.
- Through his experiment, he discovered cathode rays.
- From his observation, he noticed that they were attracted to the another so they must be negatively charged.
- He called the rays cathode rays.
- Today, they are known as electrons.
- Thomson's experiment discarded the widely held believed that atoms are indivisible.

Angiosperms can produce flowers and fruits to aid in seed dispersal.
Answer:
A)from deep within the earth
Explanation:
Answer:
= 200 mL
Explanation:
Using the dilution formula;
M1V1 = M2V2 ;
Where, M1 is the concentration before dilution, V2 is the volume before dilution, while M2 is the concentration after dilution and V2 is the volume after dilution.
M1 = 2.0 M
V1 = 50 mL
M2 = 0.50 M
V2 = ?
V2 = M1V1/M2
= ( 2.0 × 50 )/ 0.5
= 200 mL
Therefore, the volume after dilution will be, 200 mL
