which is unnecessary
A. The FeCl3solution is acidic and corrosive. Skin contact should be avoided.
B. 1M NaOH is basic and corrosive. Skin contact should be avoided
C. all of the above
I don't see a question here.
me niether just picked a random one lol
To determine which statement is unnecessary, we need to carefully read each statement and identify if any of them repeat information already provided in the other statements.
Statement A: "The FeCl3 solution is acidic and corrosive. Skin contact should be avoided."
Statement B: "1M NaOH is basic and corrosive. Skin contact should be avoided."
Both statements provide different information about different substances (FeCl3 and NaOH) and emphasize that skin contact should be avoided due to their corrosive nature.
To make a conclusion, we can analyze if there is any redundant information between statements A and B:
- Statement A discusses the properties of FeCl3, which is acidic and corrosive. It does not repeat the information about NaOH.
- Statement B mentions the properties of NaOH, which is basic and corrosive. It does not repeat the information about FeCl3.
Since there is no repetition or overlap of information, we can conclude that both statements A and B are necessary. Therefore, the answer is C: all of the above.
