The electron ionization mass spectrum of a small neutral molecule shows a base peak at 27 and a smaller peak at 26 with a relative abundance of 20%. Deduce the structure of the unknown compound. Step 1: Identify the molecular ion.
Step 2: Look for the presence of Cl or Br based on isotope pattern.
Step 3: If the molecular ion is odd or even, this indicates the number of nitrogens.
Step 4: Examine the largest peaks and calculate the difference from the molecular ion. Look for common alkyl fragments.
Step 5: Draw the structure that best fits the MS data.

Bohr's model could only explain the spectra of which type of atoms? single atoms with one electron single atoms with more than one electron bonded atoms with one electron bonded atoms with more than one electron

Electromagnets coils of wire paper clips picked up 10 3 15 6 20 9 25 12 ms. owens' class was studying magnets. ms. owens showed her students how to make an electromagnet using a nail, a d-cell battery, and plastic coated wire. the students wrapped the wire around the nail and then attached the ends to the battery. when they were finished, they tested their magnets by investigating how many paperclips their magnets could pick up. they also tested whether they could increase the strength of their electromagnets by using more coils of wire. they recorded the class average of their results in the data table seen here. ms. owens asked her students to graph their data in a line graph. how should the students label the x-axis on their line graph? a) size of battery b) number of paper clips c) number of coils of wire d) strength of electromagnet

Assume that 13.5 g solid aluminum (al) react with hcl to produce solid aluminum chloride (alcl3) salt and gaseous hydrogen (h2) at standard temperature and pressure.
