How much energy is required to raise the temperature of 12.6 grams of gaseous oxygen from 20.7 Celsius to 37.2 Celsius. answer:_ joules
Name (please print): Heat Capacity of an Unknown Metal Post Lab Questions 1.) When determining the heat capacity of the unknown metal we assumed the heat capacity of the water has a value of 4.186J/g®C. Is there an error(s) in making this error? Explain The possibility of error in the experiment can be loss of heat, the thermometer not being precise enough to give accurate values, and the capacity of the thermometer is being ignored 2.) What is the heat energy needed to raise the temperature of 6.63moles of ethanol CH;CH;OH from a temperature of 2.33°C to 17,5°C. [CH;CH;OH=46.07g/mol) [Ccusch2ow-2,46J/g°C] 3.) What is the identity of an unknown metal that absorbs 0.589KJ of heat energy where the metal is heated from 33.6°C to 241.6°C. The mass of the metal is 13.48g. [Cr= 0.160 J/g°C] [Cs»= 0.210 J/g°C] [Cc. = 0.385 J/g°C][Cz» = 0_390 J/g*C] 4.) How much encrgy is liberated when 600.2g of O, is reacted with propane in a combustion tank. Assume the following: C,Hg) + 50;(g) – 3C0;(g)+…
Revie The main reason that distillation is a costly method for purifying water is the high energy required to heat and vaporize water. Part A Using the density, specific heat, and heat of vaporization of water from Appendix B in the textbook, calculate the amount of energy required to vaporize 1.00 gal of water beginning with water at 25 °C. Express your answer using two significant figures. E = 9700 kJ Submit Previous Answers Correct The volume of the water, given in gallons, must first be converted to grams using the density from the appendix. 3780 gal x 4g xIL x 1000 mL 1 gal * 1.057 qt 0.99707 g H2O 1 ml 1.43 x 107 g H20 1L First, the water needs to be heated from 25 °C to 100 °C. The heat associated with this process is calculated using the specific heat of water from the appendix. 9 = mcAT %3D 1.43 x 107 g H,0 x 4.184 J x (100°C – 25°C) x 1 kJ g.°C x (100°C — 25°С) х 1000 J 4.481 x 10° kJ Once the water reaches 100 °C, it must then be vaporized. The heat associated with this…
