theoretical percent sulfate in AlK(SO4)2*H2O

Carminic acid is a naturally occuring red pigment and contains only carbon, hydrogen, and oxygen. It is 53.66% C and 4.0p% H by mass. A titration required 18.02 mL of 0.0406 M NaOH to neutralize 0.3602 g of carminic acid. Assuming that there is only one a...

what is between air molecules? a) air b) dust c) pollutants d) oxygen e) nothing

50 ml of.10 M HNO3 is added to 50 ml of .2M CaCl2. Calculate amount of precipitate formed?

Write net ionic equation for all the reactions that occurred with the metals. Cu(s) with Ag+ Pb(s) with Cu2+(aq) thank you

A 2.85-g sample containing only MgO and CuO is placed in a 3.00-L container. The container is filled with CO2 to a pressure of 740. torr at 20. degree C. After the reaction has gone to completion, the pressure inside the flask is 390. torr at 20. degree C...

express the barometric pressure in atm. 30.09Hg

would the molar mass of a volatile liquid, calculated using the procedure in this experiment, be incorrectly high, incorrectly low, or unaffected by the following? You forgot to measure the volume of the flask, so you used the volume printed on the g=flas...

If f(x)=sinxcosx, what are the critical points? on the interval (o, 2pi)

so it would be like 96.06g/258.33g?

no it would be 192.14/258.33?
