Question

qué number 23 and 26

Answer 1

23. saponification reaction
in pickles as vinegar is made from mixing ethanoic acid with some water and vinegar is mixed mostly in pickles and used as preservatives.

26. parallel combination
the potential will be 6V only because in a parallel combination potential remains same and current changes or gets divided.
hope it helps....

Answer 2

23##THE REACTION B/W THEM IS:-

 CH₃COOH+NaOH---> CH₃COONa +H2O And the name of the reaction is "SAPONIFICATION REACTION".

We generally use ethanoic acid(acetic acid) as "VINEGAR".

26##a)Parallel connection

##b)POTENTIAL DIFFERENCE Will remain 6V because they are in parallel connection and in parallel connection potential remain same.
