The simplest amino acid is glycine, H2NCH2CO2H. The common feature of amino acids is that they contain the functional groups: an amine group, –NH2, and a carboxylic acid group, –CO2H. An amino acid can function aseither an acid or a base. For glycine, the acid strength of the carboxyl group is about the same as that of acetic acid, CH3CO2H, and the base strength of the amino group is slightly greater than that of ammonia, NH3.(a) Write the Lewis structures of the ions that form when glycine is dissolved in 1 M HCl and in 1 M KOH.(b) Write the Lewis structure of glycine when this amino acid is dissolved in water.

Calculate the equilibrium concentration of HC2O4−HC2O4− in a 0.20 mol L−1mol L−1 solution of oxalic acid. Express your answer to two significant figures and include the appropriate units

The hydroxide ion concentration of an aqueous solution of 0.490 M acetylsalicylic acid (aspirin), HC,H;04. is [OH] = |M.

Explain the chemistry behind the difference of pH between normal rainwater and acid rain. Please answer concisely.

Limestone is a common rock used for road constructions. A construction company extracted 5 tons of the rock near a river on a rainy season. The rain washed away 2% of the rock into a nearby river which flows to a 10 acre and 15 feet deep lake in the area. With the help of relevant chemical equations, data, and calculations, explain how the washing of the rocks into the lake alters the pH of the lake.explain calculations of the final expected pH of the water in the lake

At 25 oC, Ammonia is a weak base that reacts with water according to this equation: ​NH3(aq) + H2O(aq) ⇌ NH4+(aq) + OH−(aq) Briefly explain how the equilibrium will shift (to get back to equilibrium) if the following perturbations are made to the system: (a) Addition of HCl
 (b) Addition of NaOH
 (c) Addition of NH4Cl

Calculate the pH and the equilibrium concentrations of HTe and Te²- in a 0.0948 M hydrotelluric acid solution, H₂Te (aq). For H₂Te, Ka1 = 2.3x10-³ and K₂2 = 1.6x10-11 pH = [HTE] = [Te²-] = ΣΣ

In the laboratory, a general chemistry student measured the pH of a 0.327 M aqueous solution of phenol (a weak acid), C6H5OH to be 5.228.Use the information she obtained to determine the Ka for this acid.Ka(experiment) =

A student added 1.78g of Ca(OH)2(9) to 0.250 L of 0.200 molL-1 HNO3(aq)- The mixture was carefully stirred until no further reaction occurred. Assuming that the total volume of the solution remains unchanged, calculate the pH of the resulting solution.
