1.Find the concentrations of Bicarbonate ion, carbonate ion andhydroxide ion in the sample given.

Sample: during the alkalinity experiment we obtained the P value as12.5ml and T value as 25 ml. We are using 0.01M of sulfuric acid to perform the titration.

2.A copper bar with a rectangular cross section is held withoutstress between rigid supports. Subsequently, the temperatureof the bar is raised 50 C. Determine the stresses on allfaces of the elements A and B, and show these stresses on sketches of the elements. alpha=17.5x10^-6/C E=120 GPa

3.A plastic bar fit snugly between rigid supports at room temp. (68)but with no initial stress. When the temperature of a bar israised to 160 F the compressive stress on an inclined plane pqbecomes 1700 psi. a) What is the shear stress on the planepq? alpha= 6x10^-6/F E=450x10^3 psi
