The balanced chemical reaction is:
HNO3 + NaOH = NaNO3 + H2O
We are given the amount and concentration of the reactants. The values given will be the starting point.
0.20 mol /L HNO3 (.015 L) (1 mol NaOH / 1 mol HNO3) = 0.003 mol NaOH
0.003 mol NaOH / 0.10 mol/ L NaOH = 0.03 L NaOH or 30 mL NaOH
The following are the answers:
=oxygen equals to a charge of 2-
number of atoms is -24
=Mn equals to the charge of +3
Mn= 3+3x-24=0
let x be the charge of Cl, so:
23-3=3x
20/3=x
=6.67 or 7
x= 7
= Cl has a charge of +7
You are right about your answers
Answer:
The longer the path length, the more molecules there are in the path of the beam of radiation, therefore the absorbance goes up. As you likely know from other experiences, a particular chemical species absorbs some wavelengths of radiation and not others
Answer:
