How many grams of magnesium nitride can be made from 15.00 g of nitrogen?Limiting ReactantsThe limiting reactant is the reactant present in the smallest stoichiometric amount.Chapter 3 2Chapter 3 3How many grams of magnesium nitride can be made from 15.00 g of nitrogen and 35.00 g of magnesium?Percent YieldThe percent yield of a chemical reaction is the percentage of product actually obtained when running the reaction as compared to the amount it was possible to make.Chapter 3 4 percent yield =actual yieldtheoretical yield´ 100Chapter 3 5If the reaction of 15.00 g of nitrogen and 35.00 g of magnesium actually produced 42.51 g of magnesium nitride, what was the percent yield?Chapter 6 6Electronic Structureof AtomsChapter 6 7EnergyEnergy is the ability to do work or transfer heat.Kinetic energy is energy an object possesses by virtue of its motion.Potential energy is energy an object possesses by virtue of its position or chemical composition.Chapter 6 8WavesThe amplitude of a wave is the distance from a line of no disturbance to its peak.The distance between from on peak to the next is the wavelength ().Chapter 6 9WavesThe number of waves passing a given point per unit of time is the frequency (ν).Chapter 6 10Electromagnetic RadiationAll electromagnetic radiation travels at the same velocity, the speed of light (c), 3.00  108 m/s.For electromagnetic radiation, the relationship between wavelength and frequency is: c =l nChapter 6 11The Electromagnetic SpectrumChapter 6 12Blackbody RadiationElectromagnetic energy can only be absorbed or emitted in discrete amounts, called quanta.The amount of energy in a quantum is given by:where Planck’s constant (h) is 6.626 × 10–34 J·s. E
