hello,
I have seen a video of an experiment NH4Cr2O7 + HgSCN ignited by fire the result was a kind of tentacle comming out of it, could you please explain to me how this happens.
Thank you
How many liters of water vapor can be produced if 8.9 liters of methane gas (CH4) are combusted, if all measurements are taken at the same temperature and pressure?
Draw a model showing the aqueous Ca2+ and Cl- ions (the ions surrounded by water molecules) showing the correct orientation of water molecules around the cation and anion.
You are given 5.00 mL of an H2SO4 solution of unknown concentration. You divide the 5.00-mL sample into five 1.00-mL samples and titrate each separately with 0.1000 M NaOH. In each titration the H2SO4 is completely neutralized. The average volume of NaOH solution used to reach the endpoint is 12.6 mL. What was the concentration of H2SO4 in the 5.00-mL sample?
