Empirical formula is the simplest ratio of whole numbers of components in a compound
molecular formula is the actual ratio of components in a compound .
the molecular formula for the compounds given are as follows
ethyne - C₂H₂
ethene - C₂H₄
ethane - C₂H₆
methane - CH₄
the actual ratios of the elements simplified ratio
C : H C : H
ethyne 2:2 1:1
ethene 2:4 1:2
ethane 2:6 1:3
methane 1:4 1:4
the only compound where the actual ratio is equal to the simplified ratio is methane
therefore in methane molecular formula CH₄ is the same as empirical formula CH₄
Answer:
At-207 (meaning At with the number on the top left being 207 and the number at the bottom left being 85.
Explanation:
The sum of the mass numbers has to equal on both sides, so we need 211 = 4+a
a=207
The sum of the atomic numbers as to equal on both sides, so 87=2+b
b=85
The element is determined by the mass number.
Sodium nitrate is the compound that contains both ionic and covalent bonds so the answer is (3) sodium nitrate :)))
