Answer:
C. Atom 3
Explanation:
I'm sorry if I answered this late, but hope this helps! :D
Answer:
Density, solubility, melting point, boiling point, polarity, etc.
Density - Mass divided by volume = density (scale and beaker can be used)
Boiling point- Can be determined by the capillary method (where an inverted capillary is put in the liquid you’re finding out for and the liquid is heated)
Answer:
Diazonium salts are salts formed from aromatic primary amines by diazotization. Diazonium salts are not very stable but very reactive. It therefore serves as a starting material for the preparation of various derivatives of arenes, azo dyes and pharmaceuticals.
Answer:
0.033 M
Explanation:
Let's consider the neutralization reaction between NaOH and HCl.
NaOH + HCl → NaCl + H₂O
0.4 L of 0.1 M NaOH were used. The reacting moles of NaOH are:
0.4 L × 0.1 mol/L = 0.04 mol
The molar ratio of NaOH to HCl is 1:1. The reacting moles of HCl are 0.04 moles.
0.04 moles of HCl are in 1.2 L. The molarity of HCl is:
M = 0.04 mol / 1.2 L = 0.033 M
