Answer: A. It contains three times as many hydrogen atoms as carbon atoms.
Explanation: Empirical formula is the formula which shows the atoms of the elements in the simplest ratio of atoms whereas molecular formula show the actual number of atoms.
Thus if a compound has an empirical formula of , it means there are thrice number of hydrogen atoms as carbon atoms.
The molecular formula could be written as . Thus if number of carbon atoms are n, the number of hydrogen atoms are 2n.
Answer:
Li⁺
Explanation:
Li⁺ ions has a noble gas electron configuration because it resembles that of He.
To have a noble configuration, electrons in the outermost shell must completely fill their respective orbitals.
Li⁺ is an ion that has lost one electron from the usual number of 3 thereby remaining 2 electrons.
The electronic configuration is given as;
Li⁺ 1s²
The S orbital can hold a maximum number of just two electrons.
Helium atom has two electrons with electronic configuration of 1s²
Therefore Li⁺ = 1s² = He

Answer:
Elements
Explanation:
The <u> elements</u> which are represented by a single uppercase letter, or represented by an uppercase letter followed by a lowercase letter. This tells you the types of <u>elements</u> in the compound.
Elements are one of the simplest chemical substances that cannot be decomposed in a chemical reaction or by any chemical means. They are made up of small indivisible particles called atoms, all having the same number of protons.
