part A
A sweet beverage drink contains sugar labeled as having 95 Calories (95kcal) of energy. how many kilojoules are there in 95.0 Calories?
part B
If all of this energy (95 Cal) is used to heat one quart of ice water (at 0 degrees C), what will be the final temperature (degrees C) of the water? (hint, first find the mass (g) of one quart of water).
What is the H3O+ concentration of the solution?
If 125 cal of heat is applied to a 60.0 g piece of copper at 25.0 C, what will the final temperature be? The specific heat of copper is 0.0920 cal/(g.C}) .
You will then make a Kool-Aid solution by dissolving the powder in an entire packet of lemon-lime Kool-Aid in 250.00 mL solution. You find the powder in a packet of lemon-lime Kool-Aid has a mass of 3.629 g.
at 84 degrees C the total vapor pressure of a solution contains 1.2 moles A and 2.3 moles B is 331 mmHg. Upon the addition of another mole of B to the solution, the vapor pressure increasing to 347mmHg.
For the calcium ion create a procedure for preparing a 0.100 M solution from the solid, Anyhydrous Calcium Chloride, CaCl2. Make sure to include amounts and equipment you will use for the preparation.
A 4.5 g nugget of gold absorbed 276 j of heat. What was the final temperature of the gold if the initial temperature was 25 OC ? The specific heat of gold is 0.129 j/g OC.
a 75.0 ml sample of .0500M HCN is titrated with .500 M NaOH. what is the concentration of H+ in the solution after 3.0 ml of .500 M NaOH has been added
an 8 g sample of a copper ore was dissolved in an acid solution and then reacted with NO3- from a KNO3 salt solution. it required 71.5 ml of a .155 M KNO3 solution to fully react the copper in the ore sample.
75.0 mL of a 1.80 M solution is diluted to a volume of 258 mL. A 129-mL portion of that solution is diluted using 187 mL of water.
What phase or phases are present when 250. kJ of energy is removed from this sample? Specific heat capacities:
If you take a 10.5mL portion of the stock solution and dilute it to a total volume of 0.350 L, what will be the concentration of the final solution.
