Thionyl chloride, SOCl2, is used as a very powerfuldrying agent in many synthetic chemistry experiments in which thepresence of even small amounts of water would be detrimental. Thefollowing equation is the unbalanced chemical equation.SOCl2(l) +H2O(l) SO2(g) + HCl(g)Calculate the mass of water consumed by complete reaction of52.9 g of SOCl2.
a new temperature scale is proposed based on the melting and boiling points of benzene. zero on the new scale is the

A 65 kg man is on ice skates. The skates' blades have a total contact area of 2.0 cm^2. How much pressure does the man exert on the ice
A buffer, consisting of H2PO4- and HPO42-, helps control the pH of physiological fluids. Many carbonated soft drinks also use this buffer system. What is the pH of a soft drink in which the major buffer ingredients are 8.00 g of NaH2PO4 and 6.70 g..
In an acid-base titration experiment, 50.00 mL of a 0.0500 M solution of acetic acid (ka=1.75 x 10^-5) was titrated with a 0.0500 M solution of NaOH at 25 degree C
You have just prepared a solution by weighing 20 g of sucrose, transferring it to a 1-liter volumetric flak, and adding water to the line. Calculate the concentration of the sucrose solution in terms of mM, mg/mL, and % (wt/vol).
