Suppose four 30-g ice cubes are added to a glass containing 200 cm3 of orange juice at 20,0°C.You may assume that the orange juice has a density and specific heat capacity the same as water namely: Density = 1,0 g∙cm–3 and specific heat = 4,184 J/gKThe heat of fusion (of water) is 333 J/g. Your task is twofold. You must determine: a) Whether or not all the ice will melt; and b) If your finding is that some ice will be left in the juice, you must calculate what mass of ice will be present the moment when thermal equilibrium is reached.
A student determines the molar mass of a liquid unknown by the method used in thisexperiment. She found that the equilibrium temperature of a mixture of ice and water was1.0°C on her thermometer. When she added 12.3 g of her unknown sample to the mixture, thetemperature, after thorough stirring, fell to -4.0°C. She then poured off the solution through ascreen into a beaker. The mass of the solution was 93.4 g. Kf = 1.86°C/m
What was the molality of the unknown solution? ______________ m
How much unknown liquid was in the decanted solution? ______________ gHow much water was in the decanted solution? ______________ gWhat did she find to be the molar mass of the unknown liquid, assuming she made thecalculation properly?______________ g
The following information is given for magnesium at 1 atm:
Tb = 1090.00°C
Tm 649.00°C
Specific heat solid = 1.017
Specific heat liquid = 1.339
A 33.70 g sample of solid magnesium is initially at 635.00°C. If the sample is heated at constant pressure (P = 1 atm),
