Answer:
if I'm not mistaken, it is a mixture
Every electron shell, designated by "n", has a specific number of electron subshells. The shell number has values equivalent to natural numbers (1, 2, 3, 4...), while the subshells are s, p, d and f.
The subshell that does not exist within the third shell (n = 3) is the f subshell. The energy of the f subshell is too high and cannot be accommodated in the third shell.
HCl and NaOH react based on the following equation:
HCl + NaOH ..............> NaCl + H2O
This reaction is known as a double replacement reaction. In this types of reactions, the electrolyte (and the solvent) is water and the driving force is mainly the formation of a non-electrolyte produce.
Based on this, the driving force in the above neutralization reaction is the formation if the non-electrolyte salt (NaCl)
Answer:
No. No new substance is formed during Physical change.
If you mean what group of elements react the most, the answer is the alkali metals and the halogens because they both only either need to gain or lose one electron. If you mean the most reactive element, it would be fluorine because it has the most electronegativity.
