Shown below is a student's answer from last year's exam depicting a block diagram of a flame atomic absorption spectrometer for measuring calcium. The path that light travels is indicated by (→), and the path for voltage or current by (==). Modify the diagram to correct the errors by labeling each one, describe what is wrong, and suggest the proper configuration. You can add or subtract any extra components that are necessary. Be sure to account for background absorption of molecules that may be present in the flame.
Consider the following reaction to answer the questions below. 2H2S (g) + SO2 (g) ?? 3S (s) + 2H2O (g) ?H° = -145 kJ. At what temperature would the forward reaction become non-spontaneous
Calculate the molar mass (g/mol) of the element to three significant figures.
The four major attractive forces between particles are ionic bonds, dipole-dipole attractions, hydrogen bonds, and dispersion forces. Consider the compounds below
Integrals for some of the resonances in the 1H NMR spectrum are higher than they should be due to the shear number of hydrogens in this compound
A proton in a linear accelerator has a de Broglie wavelength of 155 pm. what is the speed of the proton?

Problem- For the following balanced equation, determine how many grams of water are produced from 6g of N2H4: 2 N2H4(g) + N2O4(g) --> 3 N2(g) + 4 H2O(g) A. 6.75 g B. 1.69 g C. 3.37 g D. 10.67 g
Question- An important reaction that takes place in a blast furnace during the production of iron is the formation of iron metal and CO2 from Fe2O3 and CO.
What volume of a 0.1 M ClO- solution reacts stoichiometrically with a 10 mL solution of 0.2 M CrO2-? Use the reaction 2 CrO2- + 3 ClO- --> 2 CrO4-2 + 3 Cl- to assist in the calculation.
