Answer to Question #345993 in General Chemistry for Zaina obaid

Question

What would be the effect (increase , decrease or no change ) on the calculated value of R of each of the following ? Explain each answer.

A)an air bubble was trapped in the audiometer once it is being inverted in the beaker.

B)some Mg adheres to the inside wall of the audiometer tube after the reaction has ceased and the acid level is quite a bit lower than the piece of Mg.

C) some H2 escapes into the beaker during the reaction

Answer 1

good day in this question, we are given situations, you see the gas or the ideal gas equation, what would be the effect on the calculated value of the ideal gas constant? R. So you're seeing PV equals N. R. T. Where B. Is pressure, we volume. A number of moles are ideal gas constant and T. Rearranging this. We have our equals PV divided by anti for letter A. If the initial reading on the Udo geometry tube, which is you diameter tube is useful to know the gas volume of the volume of the gas. So if it is not zero and no correction is made, our are here has no change since it is Not zero and it has no correction made, it has no change for a letter B. The level difference is required. Id by the reading in your dormitory. True for you. Which is assuming that the volume the difference is the difference in height. So with that increasing or the level difference is decreasing since our is directly proportional to the volume which were mistakenly assumed. But they are here is will decrease for a letter C. The volume of age to Israel when the liquid level is above. Therefore, since it is above, therefore the glass here will in Greece. So because in Greece's and lastly for lottery, D. H. two gas escaped so escaping gas escaping will lower the volume. Therefore are here really decrease.
