Calculate the bicarbonate and carbonate alkalinities, in mg/L as CaCO3 , of a water having a total alkalinity of 233.0mg/L as CaCO3 and a ph of 10.47?
A solution is prepared by mixing 63.0 mL of 5.00 M HCl and 20.0 mL of 8.00 M HNO3. Water is then added until the final volume is 1.00 L. Calculate [H+], [OH -], and the pH for this solution.
If the temperature of 150.0g of water increased from 23.3C to 44.8C, how much heat was absorbed.
Determine how many moles of each Na+ and Cl- are in 1.00L of the saline solution?
Elemental analysis of putrescine (The rotten smell of a decaying animal carcass is partially due to a nitrogen-contained compounded) showed
How much energy is required to boil 45.5g of water at 100 degrees C at sea level? The molar heat of vaporization of water is 40.6 kJ/mol.
2000°C the equilibrium constant for the reaction is Kc = 2.4 103. 2 NO(g) N2(g) + O2(g) If the initial concentration of NO is 0.150 M, what are the equilibrium concentrations of NO, N2, and O2.
Potassium chloride is used in the kitchen as a salt substitute (in place of sodium chloride). Suppose you were planning to make ice cream but discovered too late that you were out of table salt for making the ice bath.
