A student performed a similar experiment with four hypothetical cations, A, B, C, and D and two hypothetical anions, X and Y. Her data is below: Analyte X Y
A+ yellow ppt yellow ppt
B+ white ppt clear, colorless solution,
C+ clear, colorless solution, NR clear, colorless solution, NR
D+ white ppt blue ppt
The student was then provided with an unknown containing one of the anions above. She reacted it with the four hypothetical cations, A, B, C, and D, her results are below: Analyte unknown yellow ppt Which of the following statements is most true with regard to this data?
a. More tests would need to be performed to identify the anion in the unknown.
b. The unknown anion is most likely Y
c. The unknown anion is most likely X

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
