A student added zinc powder to copper sulfate in a polystyrene cup and used the data she collected to calculate the enthalpy change of the reaction when 1 mole of copper sulfate reacts with 1 mole of zinc. However, she found that her value was lower than the published data for this reaction. Suggest two reasons why this might be.

In an effort to address concerns about global warming, a power plant in portland,oregon is designed to take all of its exhaust gases from its boilers and recycle the co2 using the solvay process to make sodium hydrogen carbonate. the reaction is shown below. nh3(g) + h2o(l) + co2(g) + nacl(aq) → nahco3(aq) + nh4cl(aq) how many liters each of nh3 and co2 (both at stp) would be consumed to produce 3.00 kg of sodium bicarbonate? the volume of both nh3 and co2 would be

The blackbody curve for a star name zeta is shown below. what is the peak wavelength for this star ?
