Answer:
Concentration solution A was 0.5225 M
Explanation:
10.00 mL of solution A was diluted to 50.00 mL and yields 50.00 mL of solution B
According to laws of dilution- 
where,
and
are concentration of solution A and B respectively
and
are volumes of solution A and B respectively
Here
= 0.1045 M,
= 50.00 mL and
= 10.00 mL
Hence, 
So, concentration solution A was 0.5225 M
1) it explains about stability of an atom by including stationary state.
2) it explains tge quantization of energy.
3) it gives the concept of angular momentum of a revolving electron.
what is that i cant see anything?
I don't know sorry I really need point
Answer:
NaCl + Ag(NO₃) --> Na(NO₃) + AgCl
Explanation:
Chemical equation:
NaCl + Ag(NO₃) --> Na(NO₃) + AgCl
The given reaction represent the double displacement reaction. Anion and cation of both reactant exchange with each others.
The anion of sodium chloride(Cl⁻) combine with cation of silver nitrate Ag⁺ and NO₃⁻ combine with Na⁺.
The third equation is correct while others are in correct.
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AC +BD
SORRY CAUSE IDK IF THAT HELPED :(
