A solution of hydrocloric acid has a molarity of 2.25 M HCl. If a reaction requires 5.80 g of HCI, what volume of a solution should be used? Assume a molecular mass of 36.45 g for the HCI. Calculate the number of moles of solute required: g) (36.

Which layer contains almost 90% of the atmosphere's total mass?

The trapezoid in the figure has equal nonparaellel sides. The upper base is 6 the lower base is 16 and the diagonal is 12. What is the altitude of the trapezoid

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.
