Answer:
N₃O₆
Step-by-step explanation:
Data:
EF = NO₂
MM = 138.02 g/mol
Calculations:
EF Mass = (14.01 + 32.00) u
EF Mass = 46.01 u
The molecular formula is an integral multiple of the empirical formula.
MF = (EF)ₙ
n = MF Mass/EF Mass
n = 138.02 u/46.01 u
n = 3.000 ≈3
MF = (NO₂)₃
MF = N₃O₆
Answer:
c. Substance
Explanation:
A composition variable is an intensive property that indicates the relative amount of a particular species or substance in a phase.
Since gold and silver are the least reactive metals, they do not react with water. The surface of metallic lead is covered by a thin layer of lead oxide,. As a result, it does not react with water in normal circumstances.
