Ignoring activities find out the molar solubility of copper (I) aside (CuN3) in a solution with a pH of 12.04. Ksp (CuN3) = 4.9 × 10-9; Ka (HN3) = 2.2 × 10-5.
Write a balanced chemical equation for this reaction when Ferrophosphorus reacts with pyrite making iron (ll) sulfide and a compound that is
A 0.250 gram chunk of sodium metal is cautiously dropped into a mixture of 50.0 grams of water and 50.0 grams of ice, both at 0 degrees Celsius. The reaction is 2Na(s)+2H2O(l) yields 2NaOH(aq)+H2(g) enthalpy=-368 KJ. Will the ice melt? Assuming th..
Calculate the volume of a balloon at the final temperature if this balloon at temperature of 279K and an initial volume of 2.3L is warmed to 406K.
The resultant mixture is then evaporated in a kettle to produce a jam contain- ing 67 wt % soluble solids. For a feed of 1000 kg crushed fruit, calculate the kg mix- ture from the mixer, kg water evaporated, and kg jam produced
Based upon 3 SnF2 (ag) + 2 K3PO4 (aq)> Sn3(PO4)s (s) + 6 KF (aq), a 10.000 gram sample of toothpaste containing stannous fluoride gives a 0.145 gram precipitate of stannous phosphate. What is the percentage of SnF2 in the toothpaste sample?
The additive was a compound containing carbon, hydrogen and lead (Pb). When 51.36 g of this compound was burned in excess oxygen, 55.90 g of CO2 and 28.61 g of H2O were produced. Determine the empirical formula of the compound.
