and if that wrong let me know cause jm my science class its b
Answer:
The concentration of the most dilute solution is 0.016M.
Explanation:
First, a solution is prepared and then it undergoes two subsequent dilutions. Let us calculate initial concentration:
<u>First dilution</u>
We can use the dilution rule:
C₁ x V₁ = C₂ x V₂
where
Ci are the concentrations
Vi are the volumes
1 and 2 refer to initial and final state, respectively.
In the first dilution,
C₁ = 0.178 M
V₁ = 15 mL
C₂ = unknown
V₂ = 50 mL
Then,
<u>Second dilution</u>
C₁ = 0.053 M
V₁ = 15 mL
C₂ = unknown
V₂ = 50 mL
Then,
Answer:
Co is made from incomplete combustion.
Explanation:
This essentially means if you have a fire, and not enough fuel for the fire to burn, co will always consequently be made.
Answer:
I believe Gases A and D
Explanation:
The lines in both gases match up with the lines in the unknown mixture.
1.) when components are needed to be used in different ways
2.) sublimation, filtration, evaporation, and distillation
