Under-titrating means too little indicator was added to the reaction.
TRUE
Since the volume of titrant is too small, multiplying by a small number in the calculation of citric acid makes the mass of citric acid too low.
TRUE
The reaction was stopped too quickly (before reaction was complete).
FALSE
Answer:
4 elements for C7H5(NO2)3
Answer:
[Kr] 4d10 5s2 5p4
Explanation:
The Symbol I represents Iodine. It has atomic number of 53. The full electronic configuration is given as;
1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p5
However the question requested for the configuration of I+.
I+ is a cation and it simply refers to an iodine atom that has lost a single electron. The electronic configuration of I+ is given as;
1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p4
Using Noble gas shorthand representation, we have;
[Kr] 4d10 5s2 5p4
let me know when u find out plz because i would like to know as well its one of my chemistry qustions in an assiment. :)
