Answer:
HCl -> H+ + Cl- (monoprotic acid)
Answer:
All the options are correct except "has 7 electrons"
Explanation:
The 6 M solution NaOH solution diluted before titrating the vinegar sample because pH at the equivalence point changes very rapidly . It is very useful to have dilution solution , so that number of moles that are transferred per drop of the solution is low . So, pH change smaller amount per drop. Having more dilute solution also allows the titration to use volume that is easier to work with.
If you used the 6 M solution was used then the volume required for titration would go down by a factor of 6/0.3 = 20
This means that if a titration took 20ml of the 0.3 M solution then it would take 1ml of the NaOH solution.
Titration consists of adding a controlled and known amount of standard solution with an unknown until the reaction to be complete.

Answer:
If the star has smaller mass than the Sun, it can fuse hydrogen into helium for at least a trillion years. The larger a star, the shorter its life because it fuses hydrogen into helium much more quickly. A star whose mass is more than 20 Suns will run out of hydrogen in only a few hundred million years.
