Equal volume of 0.220 M AgNO3 and 0.140 M ZnCl2 solution are mixed. calculate the equilibrium concentration of Ag+ and Zn2+
What is the heat of combustion per gram of butane?
CaCO3(s) CaO(s) + CO2(g) H°rxn = 175 kJ How will the amount (not concentration) of CaCO3(s) change with the following stresses? CO2(g) is removed. CaO(s) is added. The temperature is increased. The volume of the container is decreased.
a student placed 17.0 g of glucose in a volumetric flask added enough water to dissolve the glucose by swirling then
acetic acid has one carbon- oxygen bond that is 1.36 A nd another 1.23 A however sodium acetate has two equal carbon- oxygen bonds
Calculate the experimental value for Ksp for KHP and determine whether it is within 10% of the theoretical Ksp value (solubility = 8.0g/L). If not, give one reason why this error might have occurred.
Based on your intuitive knowledge of chemistry and physics, suggest WHY rubber is an elastomer @ room temperature but glass is not.
What is the molarity of a solution of silver perchlorate, AgClO4, if 3.2 moles of silver perchlorate is dissolved in 1.5 liters of water? Is it 2.133 M, 4.756 M, 4.8 M, or 4.810 M ?
Consider a gas at 1.00 atm in a 5.00 L container at 20 degrees celsius. What pressure does the gas exert when transferred to a volume of 2.77 L at 43 degrees celsius?
however, it takes more CaCl2 to form a White solid in one of the solutions than the other. Using the data from your experiment to help, explain what is happening when CaCl2 is reacted with the NaHCO3 (aq) or Na2CO3 (aq) solutions.
