How much heat in kilojoules is required to warm 10.0 g of ice, initially at -10.0^\circ C, to steam at 110^\circ C. The heat capacity of ice is 2.09 {\rm J}/{\rm g} ^\circ {\rm C} and that of steam is 1.84q=?kJIt is not 4.06 or 5.06...
What would you expect to observe in terms of the angle of rotation if you were to double the concentration of a sample, but kept all other variables constant?
A sample containing 0.187 g Cl- is dissolved in 50.0 mL water.How many moles of Cl- ion are in the solution?What is the molarity of Cl- ion in the solution.
The dielectric constant of water at room temperature is 78.3. Hint: your answer will come out negative because the interaction is attractive.
One method used to store energy during times of low demand is by pumping water uphill into a reservoir. When energy demand exceeds the output produced by power plants

A man has 50 kg of lipids and eats 1 kg of fish a day, which contains 0.5 ppm of methylmercury. What concentration of methylmercury will his lipids achieve?
More gas is then added to the container until it reaches a final volume of 13.9 L. Assuming the pressure and temperature of the gas remain constant, calculate the number of moles of gas added to the container.
If the initial concentration of cyclopropane is 0.150 M, what will the concentration of cyclopropane be after 22.0 hours? b) What is the half-life for the conversion process?
The heat of reaction for the combustion of cyclobutane, C4H8, is 650.3 kcal/mol. What is the heat of combustion for cyclobutane in kcal/gram?
