4. A sodium hydroxide solution was standardized by titrating 25.00mL of 0.1528 M standard hydrochloric acid. The initial burette reading of the sodium hydroxide was 2.24 mL, and the final
reading upon reaching the endpoint was 39.21 mL. What is the molarity of the sodium hydroxide
solution?
Balanced Molecular Equation:
Calculation:

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

ugh fiel iente of insistí is did kiwis jaj

i don't know people like to fight everywhere rip.
