Discuss the concentration of cations in the solution copper sulphate and zinc sulphate.
A stream of air enters a 7.50-cm ID pipe at a velocity of 60m/s at 27C and 1.80 bar (gauge). At a point downstream, the air flows through a 5.00 cm ID pipe at 60C and 1.53 bar (gauge). What is the velocity of the gas at this point
Carbon tetrachloride CCl4 was once used in the cleaning industry before people realized it was a carcinoginic compound. Millions of tons of carbon tetrachloride was made in the 50's by reacting carbon disulfide
Each copper(II) sulfate unit is associated with five water molecules in crystalline copper(II) sulfate pentahydrate (CuSO45 H2O). When this compound is heated in air above 100°C, it loses the water molecules and also its blue color.

given that the molar enthalpy of vaporization delta h for H2O(l) is 44kj at 298k, what is the standerd enthalpy change for the reaction 2H20(G)+ O2(g)---->2H2O(G)?
The densities of both gases are the same The masses of both gases are the same The number of molecules of both gases are the same Both the masses and the densities are the same
For a solution of 0.10M H3PO4, calculate the concentration of all the ionic species in solution (i.e., H+, OH-, H2PO4-, HPO42-, PO43-)
