A 37.0g sample of polyisoprene, which has a specific heat capacity of 1.880 J·g−1°C−1, is dropped into an insulated container containing 150.0g of water at 55.0°C and a constant pressure of 1 atm. The initial temperature of the polyisoprene is 5.2°C.

Assuming no heat is absorbed from or by the container, or the surroundings, calculate the equilibrium temperature of the water.

In Oceania, citizens lack privacy, have little control over their daily lives, and learn only the information that the Party chooses to tell them. Today, by contrast, information flows freely through many forms of media. People can look up any topic at any time and read about it. Through various social network sites and through phone and text messages, people have never been so connected.
 

However, the power of media can work against people as well as for them. Is all information true and accurate, or do some sources obscure truth and mislead readers? What are the potential abuses of constant connectedness? How might the screens, large and small, that surround us be used against us? Under what circumstances might our "information society" fall into the hands of a powerful but ill-intentioned group of leaders? Discuss the abuses of information and privacy in 1984 and the possibility of such abuses occurring today. Use information from the novel to support your ideas.

The rate of a certain reaction is given by the following rate law:

rate=k[H2][I2]

The rate of the reaction is measured to be 9.0 x 103 M / s when [H2] = 1.7 M and [I2] = 1.9 M. Calculate the value of the rate constant.

A chemist carefully measures the amount of heat needed to raise the temperature of a 0.76kg sample of a pure substance from −1.7°C to 3.5°C. The experiment shows that 9.6kJ of heat are needed. What can the chemist report for the specific heat capacity of the substance? Round your answer to 2 significant digits.

A chemist carefully measures the amount of heat needed to raise the temperature of a 199.0 g sample of a pure substance from 22.3°C to 32.8°C. The experiment shows that 3.87 kJ of heat are needed. What can the chemist report for the specific heat capacity of the substance?
