Answer:
Via covalent bonds
Explanation:
Atoms in molecules are bonded together via covalent bonds. Covalent bonds are bonds that are formed by sharing of the valence electrons between two atoms.
The atoms can be of the same kind or of different kinds.
- In most molecules, the two atoms are connected by sharing of their valence electrons.
- This way, each atom can attain stability by becoming isoelectric with the nearest noble gas.
- Some molecules are monoatomic, some are polyatomic.
Conductivity is the ability of a substance to allow charge or electricity to pass through it. Metals have a lot of free electrons and are considered as good conductors while non-metals do not conduct electricity
1) In the given examples:
Al is a metal, Na is an alkali metal while P is a non-metal
The decreasing order of conductivity would be:
Al > Na > P
2)
Both Al and Ga are metals while B is metalloid.
Among Al and Ga, Al is a solid at room temperature and a better conductor of electricity. hence the decreasing order would be:
Al > Ga > B
Answer:
Theobromine
Explanation:
It seems like it is chained up into a pentagon.
Answer:
0.45M
Explanation:
The following were obtained from the question:
C1 = 0.75M
V1 = 100mL
V2 = 165mL
C2 =?
Applying the dilution formula C1V1 = C2V2, the concentration of the diluted solution can be calculated for as follows:
0.75 x 100 = C2 x 165
Divide both side by 165
C2 = (0.75 x 100) /165
C2 = 0.45M
The concentration of the diluted solution is 0.45M
