(a) Interpretation: The balanced equation corresponding to the single-replacement reaction that occurs when a soft, gray piece of lithium metal is added to water is to be stated. Concept introduction: During a chemical reaction , the composition of the substance undergoes a change. In a single-replacement reaction, a more reactive element displaces another element from a compound or its solution. The substance that is displaced is less reactive and has lesser tendency to undergo reaction than the other element.

Please help me with # 4 and 5. Thanks in advance!

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.…
