If 10.0 g of water is initially heated from 20°C to 100°C, and then it is continually heated through its phase change (it is vaporized), what is the total amount of energy necessary to carry out this process?
A 500.0 g iron bar at 212 degrees C is placed in 2.0L of water at 24.0 degrees C. What will be the change in temperature of the water?

We did a lab in Chem where we put a liquid into a flask, secured foil on the top and poked a hole in the foil so the vapor could push out the air
Calculate the pH during the titration of 100.0 mL of 0.200 M HCl with 0.400 M NaOH. First what is the initial pH (before any NaOH is added)? What is the pH after 31.9 mL of NaOH are added?
Using the alpha diagram for carbonate in a closed system, at what pH would the molar CO2 concentration be approximately equal to the molar bicarbonate concentration
Assuming the solution has a heat capacity of 4.18 J/°C·g and assuming no heat loss to the calorimeter, calculate the enthalpy change for the dissolution of NH4NO3 in units of kJ/mol.
Sulfuric acid is formed when sulfur dioxide reacts with oxygen and water. write the balenced chemical equation for the reaction. if 12.5 mol SO2 reacts, how many mol H2SO4 can be produced. How many mol O2 is needed.
Suppose that 33.55 g of ice at -12.9°C is placed in 54.72 g of water at 99.8°C in a perfectly insulated vessel. Calculate the final temperature. (The molar heat capacity for ice is 37.5 J K-1 mol-1 and that for liquid water is 75.3 J K-1 mol-1. Th..
