Explain how a calibration curve could be used to determine an unknown quantity
Classify each chemical reaction: i# k2so4(aq) + ba(no3)2(aq) -->2kno3(aq)+baso4(s)## ii # 2Na(s)+F2(g)-->2NaF(s)## iii # Cl2 (g) +CuCl2(aq)+Br2(l)
477 J amount Energy is added to a 74.0 grams sample of H 2 O at a temperature of 21 degree Celsius. Determine what will be the final temperature of the H 2 O?
If 4.00 g of the unknown compound contained 0.133 mol of and 0.267 mol of H , how many moles of oxygen, O , were in the sample?
Calculate the pH of this buffer solution after the addition of 0.010 moles of solid sodium hydroxide to the buffer
suppose that a 5.0X10^-5 M solution of Ba(OH)2 is prepared. What is the pH of the solution?
The below table lists pressure and volume measurements for air in a cylindrical piston of an air compressor. The variables may be assumed related
Hydrochloric acid HCl are permitted to react at atmospheric pressure and the volume change is -71.1 liters then determine how much PV work is done?
A piece of sodium metal reacts completely with water as follows. 2 Na(s) + 2 H2O(l) ->2 NaOH(aq) + H2(g) The hydrogen gas generated is collected over water at 25.0°C. The volume of the gas is 295 mL measured at 1.00 atm.
22.3 g of a substance X dissolves in enough water to make 0.507 L of a 0.779 M solution. Calculate the molar mass of X in g/mol.
A sample of gas occupies 1.55L at STP. Remember, pressure at STP is 1.0 atm. What will the volume be if the pressure is increased to 50 atm while the temperature remains constant
A gas occupies a volume of 458 mL at a pressure of 1.01 kPa and a temperature of 295 K. When the pressure is changed, the volume becomes 477 mL.
The answer to Kinetics, The symmetry factor Beta was determined to be 0.4 for an activation controlled Ag deposition process. At overpotential n = -0.400 V the current density was found to be j = -5.125 A/dm^2.
Calculate the pressure of a helium sample at -207.3°C and 768 mL if it exerts a pressure of 175 kPa at 25.0°C and 925 mL
