A copper cylinder has a mass of 76.8 g and a specific heat of 0.0920 J/ g degrees c. It is heated to 86.5 degrees c and then put into 68.7 g of turpentine whose temperature is 19.5 deg c. The final temperature of the mixture is 31.9 deg c. What is the specific heat of the turpentine?

Real help & answers only plz. Thx.

A100-watt light bulb radiates energy at a rate of 100 j/s. (the watt, a unit of power or energy over time, is defined as 1 j/s.) if all of the light emitted has a wavelength of 525 nm , how many photons are emitted per second?

Consider the following reaction at equilibrium. 2co2 (g) 2co (g) + o2 (g) h° = -514 kj le châtelier's principle predicts that the equilibrium partial pressure of co (g) can be maximized by carrying out the reaction a. at high temperature and high pressure b. at high temperature and low pressure c. at low temperature and low pressure d. at low temperature and high pressure e. in the presence of solid carbon

Answer explain why it is not possible to deduce a complete order of reactivity.
