Question

Which statement correctly compares barium nitrate (Ba(NO3)2) and scandium nitrate (Sc(NO3)3)?

A. They contain the same number of NO3 groups.


B. They contain the same number of oxygen atoms.


C. They contain the same total number of atoms.


D. They contain the same number of elements.

Answer 1

I think the answer would be D

Explanation

Because, the elements are containing the same number of elements which is NO3 )2) and NO3)3 I hope this helps ^^

Answer 2

D. They contain the same number of elements.

Step-by-step explanation:

The formula (Ba(NO3)2) contains 9 atoms.

1 Barium atom (Ba)

Contains 2 NO3 groups -

2 Nitrogen atoms (N) x 2

6 Oxygen atoms (O3) x 2

3 Elements in total

The formula (Sc(NO3)3) contains 13 atoms.

1 Scandium atom (Sc)

Contains 3 NO3 groups -

3 Nitrogen atoms (N) x 3

9 Oxygen atoms (O3) x 3

3 Elements in total

They do not have the same number of atoms.

They do not have the same number of oxygen atoms.

They do not contain the same number of NO3 groups.

They do have the same number of elements.
