The gases carbon dioxide, oxygen, and argon are mixed in a container. all gases have the same partial pressure, and the total pressure of the container is 32,680 pa. what is the partial pressure of argon ?

Iwll give extra points to who gets this for ! what type of reaction is this? ?

In which situation can a mixture always be called a solution

The content of manganese (mn) in steel was determined spectrophotometrically and with the use of the standard addition method. an unknown sample of mn from a digested steel sample gave an absorbance of 0.185 when analyzed spectrophotometrically. when 5.00 ml of solution containing 95.5 ppm mn was added to 50.0 ml of the unknown steel solution (digested sample), the absorbance was 0.248. calculate the concentration, in parts-per-million (ppm), of mn in the digested steel sample solution.
