13. In a gravimetric analysis, a student predicted that 250 g of precipitate should form. During the experiment, the student filtered their solution and the mass of the dried precipitate was 275 g. What would be the most likely reason for this discrepancy? Precipitate was lost during filtration Precipitate was contaminated Precipitate was not completely dried Precipitate had broken down

Compute the ionization potential of a positronium (an "atom" made by an electron bonded to a positron). SHOW FULL AND COMPLETE PROCEDURE IN AN ORDERED WAY

Just part b!!!

help please answer in text form with proper workings and explanation for each and every part and steps with concept and introduction no AI no copy paste remember answer must be in proper format with all working

state if true or false 1. Considering that concentration and the size of sample container are the same, a sample with a higher molar absorptivity will have a higher TRANSMITTANCE than a sample with the lower E (molar absorptivity). 2. Considering that concentration and the size of sample container are the same, a sample with a higher molar absorptivity will have a higher ABSORBANCE than a sample with the lower E (molar absorptivity). 3. The higher the concentration of a sample is the higher the transmittance will be. 4. Spectrophotometry is the study of how light interacts with matter 5. During an absorbance reading, light must pass through the opaque side of the cuvette. 6. Distilled water is an acceptable blank solution for any sample

Identify the following spectra. Full credit is only given if all pertinent peaks are assigned on the spectrum (~5-6 peaks). Label the peaks on the spectrum and place the structure of the compound in the box on the lower left-hand corner of the spectrum.  please on the graph circle the peak

this is wrong.....  here s te response... can youprovide correct please????

I need to mention planes on these peaks Planes find it.  Only best analytical chemistry experts solve it

Please do D, E, and F
