Answer : The concentration of nitrate ions is 0.450 m.
Solution : Given,
Molarity of 
= 0.225 m
The balanced ionic equation is,
From the reaction, we conclude that the 1 mole of produces 2 moles of 
ions. That means the concentration of nitrate ions is twice the value of .
then, 0.225 m of gives 2 × 0.225 of ions
Now the concentration of ions is equal to 0.450 m.
A chemical formula shows the kinds and numbers of <u>atoms</u> in the smallest representative unit of a substance.
<u>Explanation:</u>
In chemistry, a formula unit is the empirical formula of "ionic or covalent network solid compound" that is used as an independent entity for "stoichiometric calculations". This formula is a representation of a molecule that uses chemical symbols.
The unit is the lowest whole number ratio of ions represented in an ionic compound. It gives the numbers of atoms representing the "smallest representative" unit of a substance. The number of atoms also tells us about the chemical and physical properties of the compound formed.
Answer:
1 oxygen 1 hydrogen hydrogen peroxide I think
Answer:
A noble gas configuration of an atom consists of the elemental symbol of the last noble gas prior to that atom, followed by the configuration of the remaining electrons. So for sodium, we make the substitution of [Ne] for the 1s22s22p6 part of the configuration. Sodium's noble gas configuration becomes [Ne]3s1. That is the answer.
