Which of these formulas represents 1 atom of sodium (na) chemically combined with another element? a. pbs b. nacl c. 2naoh d. na2h3io6

B. NaCl

Explanation:

Which of these formulas represents 1 atom of sodium (Na) chemically combined with another element?

A. PbS. NO. There are not atoms of Na in this formula.

B. NaCl. YES. 1 atom of Na is combined with 1 atom of Cl.

C. 2NaOH. NO. 1 atom of Na is combined with 1 atom of O and 1 atom of H, thus, it is combined with more than 1 element.

D. Na₂H₃IO₆. NO. There are 2 atoms of Na in this formula.

vapour or gas assuming atmospheriv pressure

you get 2.3=1.21*\frac{a}2 or 4.6=1.21a or a=3.802 (b)
