Answer:
The rows on the periodic table are called periods. All the elements in a period have valence electrons in the same shell. The number of valence electrons increases from left to right in the period. When the shell is full, a new row is started and the process repeats.

I hope it helps plz let me know if it is right or wrong.</h2>
C because we need materials in the lab
Answer:
Yes
Explanation:
Let's write the reaction as
CV⁺+ OH⁻ ⟶ CVOH
The reaction is first order in [CV⁺] and in [OH⁻], so the rate law is
rate = k[CV⁺][OH⁻]
A bimolecular collision between a crystal violet ion and a hydroxide ion as an elementary step would predict the observed rate law.
However, other plausible mechanisms may predict the same rate law.
Water is held together by hydrogen bonds.
Water molecule: H2O:
--- = hydrogen bond
