Considering the balanced chemical equation at the beginning of Section 4.2, why is it incorrect to say that if we burn 2 kg of octane, we would get 16 kg of CO2 as a product?
What is the rate of reaction when the initial concentrations of NO and O2 are 0.030 M and 0.025 M, respectively? 2 NO(g) + O2(g) --> 2 NO2(g)
concentration was dissolved in HCl and diluted to 100.0 mL. Aliquots of 10.00 mL of this unknown solution were added to different volumes of a 2.08 ÃŽ¼g/mL Ca standard solution and diluted to 200.0 mL. Find the weight percent of Ca in the rock sam..
The reaction of 0.25 g magnesium with 100 mL of 1 M hydrochloric acid (density d = 1.02 g/ml) raises the temperature of the solution from 20 °C to 35 °C . The specific heat for HCl is 3.93 J/(g.C).
