Answer:

1:1

Explanation:

The ratio of metal cationic atom to non-metal anionic atom in the compound is 1:1.

This is an ionic compound.

This is because metal cationic atom has two valence electrons.
Non-metal anionic oxygen has six valence electrons
Calcium loses two of its valence electrons to be isoelectronic with Ar and this confers a stable configuration to it.
Non-metal oxygen atom accepts the electrons and adds 2 to its 6 electrons to become isoelectronic with neon.
So, 1 metal cationic atom combines with 1 non-metal anionic atom to form the compound.

To 225 mL of a 0. 80 M solution of Kl, a student adds enough water to make 1. 0 L of a more dilute Kl solution. What is the mola

Lady_Fox [76]

Answer: 0.18 M

Explanation:

Initial molarity, M1 = 0.8 M

Initial olume, V1 = 225 ml

Final volume, V2 = 1000 ml

Final Molarity, M2 = M1V1/V2

= 0.8 x 225/1000

= 0.18 M
