Which of the following is the correct chemical formula for lithium carbonate?
A
LiCO2
B
Li2CO3
C
LiCO3
D
Li2(CO3)2
Verified step by step guidance1
Identify the ions involved in lithium carbonate: lithium ion (Li\^+) and carbonate ion (CO\_3\^{2-}).
Determine the charges of each ion: lithium ion has a charge of +1, and carbonate ion has a charge of -2.
Balance the total positive and negative charges to make the compound electrically neutral. Since carbonate has a -2 charge, you need two lithium ions (each +1) to balance it.
Write the chemical formula by placing the number of lithium ions before the carbonate ion, resulting in Li\_2CO\_3.
Confirm that the formula Li\_2CO\_3 represents the correct ratio of ions and is the proper chemical formula for lithium carbonate.
