Consider the reaction c12h22o11(s) +12o2(g) > 12co2(g)+11h2o(l)
in which 10.0 g of sucrose, c12h22o11, was burned in a bomb calorimeter with a heat capacity of 7.50 kj/c. the temperature increase inside the calorimeter was found to be 22.0 c. calculate the change in internal energy, delta e, for this reaction per mole of sucrose. express the change in internal energy in kilojoules per mole to four significant figures.

deltae = ? kj/mol

1.aluminum chloride (alcl3), and sodium hydroxide (naoh) can react to form aluminum hydroxide (al(oh)3) and sodium chloride (nacl).    you have 13.4 g of aluminum chloride and 10.0 g of sodium hydroxide. answer the following questions: •what is the balanced equation for this reaction? •if you use all 13.4 g of aluminum chloride, how many grams of aluminum hydroxide can be formed? work must be shown to earn credit •if you use all 10.0 g of sodium hydroxide, how many grams of aluminum hydroxide can be formed? work must be shown to earn credit •how many grams of aluminum hydroxide will actually be made?     which reagent is limiting? explain your answer.

The peak wavelength for the blackbody curve of a star is in the uv range. assuming the radiation from this star can reach earth, would you be able to see it?

An observation that requires measurement is called quantitative observable or qualitative
