Answer the fоllоwing questiоn. Whаt is the limiting reаctаnt, if any, when 7.0 moles of Sr(NO3)2 react with 4.0 moles of Cs3PO4?Hint: Use MR from the balanced equation and cancel units. 3Sr(NO3)2 + 2Cs3PO4 → 6CsNO3 + Sr3(PO4)2 Chose your final answer here.

Which оf the fоllоwing compounds corresponds to the NMR spectrum shown below? Click to Show Imаge Description A proton NMR spectrum with chemicаl shift in ppm on the horizontаl axis ranging from 10 on the left to 0 on the right. In the aromatic region, a group of peaks appears near 8.0 ppm and another cluster near 7.3 ppm. A tall group of closely spaced peaks appears near 5.2 ppm. A smaller peak appears near 3.3 ppm. An inset expansion is shown in the upper left corner of the spectrum, labeled "Offset: 2.0 ppm," displaying a zoomed-in view of peaks in that region showing fine splitting detail. A red integration curve overlays the spectrum in a staircase pattern, stepping upward at each peak group from left to right. The steps at the aromatic peaks near 8.0 and 7.3 ppm are moderate. A large step occurs at the peaks near 5.2 ppm. A smaller step appears at the peak near 3.3 ppm.
Which оf the fоllоwing compounds corresponds to the NMR spectrum shown below? Click to Show Imаge Description A proton NMR spectrum with chemicаl shift in ppm on the horizontаl axis ranging from 10 on the left to 0 on the right. The baseline is flat across most of the spectrum. A cluster of closely spaced peaks appears near 7.0 to 7.3 ppm. A single peak appears near 3.5 ppm. A smaller group of peaks appears near 2.5 ppm. Two tall, closely spaced peaks appear near 0.9 ppm. A red integration curve overlays the spectrum in a staircase pattern, stepping upward at each peak group from left to right. The step heights increase progressively, with the smallest step at the peaks near 7 ppm, a moderate step at the peak near 3.5 ppm, another moderate step at the peaks near 2.5 ppm, and the largest step at the peaks near 0.9 ppm.
