Consider the unbalanced equation for the decomposition of silver nitrate: AgNO3 (s) - - - >Ag (s) + NO2 (g) + O2 (g) 1. Write the balanced equation for the reaction. 2. When 54.0g of AgNO3 is heated, 4.60g of O2 is formed.

Water flows at the rate of 0.5 kg/s in a 2.5-cm-diameter tube having a length of 4 m. A constant heat flux is imposed at the tube wall so that the tube wall temperature is always 50°C higher than the water temperature.

Which of the following equations represents a double-displacement reaction? A. FeS (s) + 2HCl (aq) ® H2S (g) + FeCl2 (aq) B. 2Sb (s) + 3I2 (g) ® 2SbI3 (s) C. Zn (s) + H2SO4 (aq) ® ZnSO4 (aq) + H2 (g) D. 2HgO (s) ® 2Hg (l) + O2 (g)

Consider the Williamson ether synthesis between 2-naphthol and 1-bromobutane in strong base. A reaction was performed in which 0.51 g of 2-naphthol was reacted with a slight excess of 1-bromobutane to make 0.29 g of 2-butoxynaphthalene.
