What is the transmittance if you measure the potassium permanganate on the preset conditions at 544 nm and 100 μM?
An iron chloride compound contains 55.85 grams of iron and 106.5 grams of chlorine. What is the most likely empirical formula for this compound
Question- The hydrogen atom is not actually electronegative enough to form bonds to xenon. Were the xenon-hydrogen bond to exist, what would be the structure of XeH4? Double-click any atom and type Xe to change the label. Draw the molecule by plac..
suppose the experiment was done with 1.0m H3PO4 as the acid. What would be the stoichiometric ratio, mol H3PO4/mol NaOH at the intersection of ascending and descending portions of the graph?
Approach the research proposal is to familiarize yourself with the literature in your topic area (see, there's a reason I'm making you do the Literature Report
Explain a sample of liquid mercury mass 67 g and temperature 92 C is poured into 96 g of H2O at 15 C. Compute the final temperature of the mixture assuming no heat is lost. The heat capacities of Hg as well as H2O are 27.98 and 75.33 J/mol/K, resp..
Perform titration at least three times to get an average number, standard deviation and 90% confidence interval. Check your answer against the computer. In your discussion explain why your results may differ from actual value.
Compute the translational, rotational, vibrational (compute excluding and including the zero point energy term), as well as electronic (compute taking the zero of energy to be that of the ground state molecule as well as that of the separated atom..
