A mixture is made by mixing 40.7 mL 0.000200 M HCl with 38.3 mL of 0.000180 M NaOH. Based upon these values, the mixture's pH will be
determine the average separation distance between the quantum dot and an adjacent gold nanoparticle for the molecular beacon (in the absence of the target sequence).
calculate the heat energy released when 15.1g of liquid mercury at 25 degrees C is converted to solid mercury at its melting point
Draw the structure of the cis and trans isomers of the compound you prepared from last question. Why did you obtain the trans isomer?
Spilling some of the reaction mixture. b.Adding too much baking soda. c.Adding too much vinegar. d. Not allowing the reaction to go to completion.
Sodium bicarbonate is called baking soda because when heated, it releases carbon dioxide gas, which is responsible for the rising of cookies, doughnuts, and bread. Calculate the volume (in liters) of carbon dioxide by heating 4.37 g of sodium bica..
Since the air is going at 25 C and assuming atmospheric pressure, calculate the actual volume of air. Calculate the number of moles of CO2, H2O, O2 and N2 in the flue gas
