想請問A選項為什麼axb不是log5+log2 C選項看起來跟A選項很像 我好像分辨不出來

已知a=log5,b=log2,下列何者正確? 5 (A)axblog 5+log2 (B) a÷b= log 5 =- a+b=1 (D)a-b= 2 log 2 , a=log 5 b=log 2 (A) axb=(log5)x(log2) a log 5 (B) = b log2 = log₂ 5 (C) a+b=log5+log 2 = log(5×2) = log 10=1 (D) a − b = log 5-log 2 = log (2) 5

想問這題

請問19為什麼不能選C或D？謝謝

Britain celebrated the Coronation of King Charles III in May 2023. This grand event, the name of which is 16 from the Latin word "corona" meaning crown, marked the crowning of a new monarch after a 70-year gap since Queen Elizabeth II's coronation in 1953. The ceremony took 17 in Westminster Abbey, a site that has hosted coronations for over 900 years, and followed several traditional stages. The coronation begins with the recognition stage, where the Archbishop of Canterbury introduces the new king or queen to the gathered crowd, who then cheer, "God save the king!" or "God save the queen!" 18 is the oath-taking, where the monarch promises to uphold the law and the Church of England. This is followed by the anointing stage, during 19 the monarch is anointed with holy oil while seated on the coronation chair, with a gold cloth covering the ceremony from view. During the investiture stage, famous coronation artifacts like the sceptre and orb are presented before placing the crown on the monarch's head. Finally, dressed in jeweled golden artifacts and a crown weighing over two kilograms, the new sovereign walks to the seat as the newly crowned monarch of Britain. 20. They then take their 16. (A) deprived (B) derived (C) defied (D) despised

Experiment 7 Experiment 7 The partition of Organic acid between Water and Organic solvent Objectives Understand the partition of a solute between two immiscible solvents. Introduction A chemical analysis that is performed primarily with the aid of volumetric glassware (e.g., pipets, burets, volumetric flasks) is called a volumetric analysis. For a volumetric analysis procedure, a known quantity or a carefully measured amount of one substance reacts with a to-be-determined amount of another substance with the reaction occurring in aqueous solution. The volumes of all solutions are carefully measured with volumetric glassware. The known amount of the substance for an analysis is generally measured and available in two ways: 1. As a primary standard: An accurate mass (and thus, moles) of a solid substance is measured on a balance, dissolved in water, and then reacted with the substance being analyzed. 2. As a standard solution: A measured number of moles of substance is present in a measured volume of solution - a solution of known concentration, generally expressed as the molar concentration (or molarity) of the substance. A measured volume of the standard solution then reacts with the substance being analyzed. The reaction of the known substance with the substance to be analyzed, occurring in aqueous solution, is generally conducted by a titration procedure. The titration procedure required a buret to dispense a liquid, called the titrant, into a flask containing the analyte. A reaction is complete when stoichiometric amounts of the reacting substances are combined. In a titration this is the stoichiometric point. In this experiment the stoichiometric point for the acid-base titration is detected using a phenolphthalein indicator. Phenolphthalein is colorless in an acidic solution but pink in a basic solution. The point in the titration at which the phenolphthalein changes color is called the endpoint of the indicator. Indicators are selected so that the stoichiometric point in the titration coincides (at approximately the same pH) with the endpoint of the indicator.
