Explanation:
Sulfur has 6 valence electron
Valence electron shows group( in column)
In the first 85.0 s of this reaction, the concentration of no dropped from 1.12 m to 0.520 m .
What is rate of a reaction?
The speed at which a chemical reaction takes place is the rate of the reaction. It is the concentration change per unit time of a reactant in a reaction.
Since the concentration of NO reduces to half its initial concentration in 85 seconds that is from 1.12m to 0.520m, it can be said that 85 seconds is the half life interval for the reaction, <u>Hence on average, </u><u>half reaction</u><u> is completed in the time interval of </u><u>85 seconds</u><u>.</u>

Spillages on a tiled floor, a highly polished floor surface, a damp smooth surface with no mat.
(A.) Nickel and oxygen reacting chemically could create a compound. (Most likely some sort of oxide)
The pure silver is only made up of one element, so it can't be a compound.
The sandwich and all it's components may contain chemical compounds, but is not a compound in itself.
While it is possible that the material the nails are made out of is a compound, we are not given this information. Simply stating that nails (no matter the size) are in a box, does not make it a compound.
Answer:
1.) 7
2.) 5
3.) stable
4.) 5A
5.) 5
6.) The properties would be more stable to property of phosphorous because same group and valenve electronics and they also have same chemical
