What masses of calcium sulfate and phosphoric acid can be produced from the reaction of 1.0kg calcium phosphate with 1.0kg concentrated sulfuric acid (98% H2SO4 by mass)?
Ca3(PO4)2+3H2SO4->3CaSO4+2H3PO4
An oil bath maintained at 50.5 oC loses heat to its surroundings at the rate of 4.68 kJ/min. Its temperature is maintained by an electrically heated coil with a resistance of 60 operated from a 110 V line.
Separation scheme for isolating benzoic acid, Could you please show me a separation scheme for isolating benzoic acid from a reaction mixture if mixing a Grignard
A 4.867 g sample of a monoprotic acid was dissolved in water. It took 30.24 mL of a 0.1578 M NaOH solution to neutralize the acid. Calculate the molar mass of the acid.
equilibrium constant, Kp, for the reaction = 0.295 (at 400 degrees C.)then write the kp of the reaction and Calculate kc at 400 degree Celsius.
A solution of 0.264 M NaOH is used to neutralized 54.0 mL H3PO4 solutions. if 1.0 mL of NaOH is required to reach end point what is the molarity of H3PO4

Important information about Liquid Crystals, Are there differences between the cholesteryl benzoates and the cholesteryl esters having long carbon chains?
The insecticide DDT has a half-life in the human body of about 7 years. That is, in 7 years its concentration.( Although DDT is no longer in use in the United States).
The magnesium and calcium ions present in seawater([Mg2+] = 0.059 M and [Ca2+] = 0.011 M) can be separated by selective precipitation with KOH.
