Chlorine gas can be produced commercially by passing an electric current through a con- centrated solution of sodium chloride (brine). The unbalanced equation is NaCl(aq) + H2O(l) - .NaOH(aq) + Cl2(g) + H2(g) . If the brine contains 440 g of NaCl, how much Cl2 can be produced?
Calculate the moles of N2 that will be in 224 L at STP and the partial pressure of O2 in Pa for air at 2.50 atm pressure
What is the nature of the substance(non polar, polar, ionic) and intermolecular force(ionic or van der waals if van der walls give type including h-bond)
In the reaction Cu(s) + 2AgNO3(aq) --> 2Ag(s) + Cu(NO3)2(aq), what number of grams of silver can be produced from 49.1 g of copper?
What is the pH of a solution in which 323 mL of HCl(g), measured at 26.8 degrees Celsius and 1.02 atm, is dissolved in 1.5 L of aqueous solution?
what will be the final temperature of the solution in the calorimeter? The heat of solution,delta H solution, ofCaCl2of is -82.8kj/mole.
We are asked to construct an energy level diagram (molecular orbital) for the molecule SO. We are then asked to comment on the ionic species of SO - bond order, bond distance etc. So far so good.
given the balanced equation representing a reacction: 2C2H6+7O2=4CO2+6H2O determine the total number of moles of oxygen that react completely with 8.0 moles of C2H6
A 515 g piece of copper tubing is heated to 95.0°C and placed in an insulated vessel containing 57.0 g of water at 30.0°C.
Strontium carbonate decomposes upon heating to strontium oxide and carbon dioxide. Calculate the number of g of carbon dioxide produced by heating 10.7 g of strontium.
