Answers

Answer 1

Answer:

Answer:Fe2O3

Explanation:

the roman numeral tells you the charge of the metal, and you know oxygen is -2 charge so you need the least common multiple of +3 and -2 so that they cancel out, which is 6 so you need 2 of the +3 and 3 of the -2

What types of atoms are shown in a skeletal model of an organic molecule?A. Atoms of every element except carbon
B. Atoms of every element except hydrogen
C. Atoms of every element
D. Atoms of every element except carbon and hydrogen

Answers

Answer:

Atoms of every element are shown in a skeletal model of an organic molecule.

Explanation:

Skeletal model of an organic molecule consists of various skeletal atoms that are used in making up of the molecule. Various conventions of hydrogen and carbon atoms are employed in it. The molecules bonding and certain representation of molecular geometry are shown in the structural formula.

Use of skeletal formula is ubiquitous in organic chemistry. Thus, in organic chemistry atoms of every element are shown in the skeletal model of an organic molecule
