The chlorine atom bonds through covalent bond to obtain an octet structure so two atoms of 2,8,7 come together and HCl consists of both metal and nonmetal which is the the covalent bonding principle so H and Cl share the 8 valence electrons to obtain an octet structure.

Answer:</h3>
40 atm

Explanation:</h3>
- According to Boyle's law, the pressure and the volume of a fixed mass of a gas are inversely proportional at constant absolute temperature.
- That is;

- At varying pressure and volume,
P1V1 =P2V2
In this case,
Initial volume, V1 = 2 L
Initial pressure, P1 = 1 atm
New volume, V2 = 0.05 L
We are required to calculate the new pressure,
Rearranging the formula;
P2 = P1V1 ÷ V2
= (1 atm × 2L) ÷ 0.05 L
= 40 atm
Therefore, the pressure required is 40 atm
Answer:
Following DNA replication, the chromosome consists of two identical structures called (sister chromatids), which are joined at the centromere.
They move faster at a higher temperature i believe. i hope this helps
