The measurements that were central to Lavoisier theory are to be determined. Also, the key discovery made by Lavoisier is to be determined. Concept introduction: Lavoisier theory was based on the quantitative measurements. It includes the following series of experiments: 1. Mercury calx was decomposed into mercury and gas when heated. The total mass of mercury calx was equal to the sum of masses of mercury and the gas. 2. Mercury and the gas were combined to form mercury calx again. The total mass remains constant. 3. Mercury was heated in a fixed volume of air to form mercury calx and in this process, four-fifths of the air was left. 4. The burning candle was extinguished when placed in the remaining air.

A small artisanal cheesemaker is testing the acidity of their milk before it coagulates. During fermentation, bacteria produce lactic acid (K₁ = 1.4 x 104), a weak acid that helps to curdle the milk and develop flavor. The cheesemaker has measured that the developing mixture contains lactic acid at an initial concentration of 0.025 M. Your task is to calculate the pH of this mixture and determine whether it meets the required acidity for proper cheese development. To achieve the best flavor, texture and reduce/control microbial growth, the pH range needs to be between pH 4.6 and 5.0. Assumptions: Lactic acid is a monoprotic acid H H :0:0: H-C-C H :0: O-H Figure 1: Lewis Structure for Lactic Acid For simplicity, you can use the generic formula HA to represent the acid You can assume lactic acid dissociation is in water as milk is mostly water. Temperature is 25°C 1. Write the K, expression for the dissociation of lactic acid in the space provided. Do not forget to include state symbols.…
