Which of the following correctly identifies the number of each element involved in the chemical formulas

1 answer:

8 0

D
If an element doesn’t have a number next to it that means there is only one. There a 4 hydrogens because the number is attached to the hydrogen atom. If there were 4 NH molecules the NH would be in parentheses and the 4 would be outside. Same goes for the oxygen atom and CO3 molecule.
