2-...","1-What is the difference between the end point and equivalence point in a titration? How can you tell them apart? 2- If you have 15 mL of 2 M HCl, how many moles are present in solution? 3-Student 1 is titrating NaOH into HCl, the student pours 10.00 mL of 2 M HCl into an erlenmeyer flask and adds 2 drops of phenolphthalein indicator and 15 mL of deionized water. The student places the burette with NaOH inside of it above the acid solution and records that there are 30 mL of 1 M NaOH in the burette. The student turns the stopcock to begin the titration. The solution in the flask turns pink and the student stops the titration. The student records that the volume of 1 M NaOH is now at 9 mL. How many moles of HCl were there? How many moles of NaOH were added to the flask during the titration? What is the experimental molar ratio of NaOH:HCl? What is the theoretical ratio? What is the percent error?

Critical Thinking Principles
Prepare: In preparation for discussing the importance of critical thinking skills, please read Chapters 1 through 3 of Think Smarter: Critical Thinking to Improve Problem-Solving and Decision-Making Skills, as well as the following articles: “Critical Thinking and the Challenges of Internet,” “Common Misconceptions of Critical Thinking.” Critical thinking gets you involved in a dialogue with the ideas you read from others in this class. To be a critical thinker, you need to be able to summarize, analyze, hypothesize, and evaluate the new information that you encounter. Write: For this discussionDefine, describe, and explain the principles of critical thinking.Search the Internet, media, or the Ashford University Library, and find an example of good, careful (critical) thinking, and explain why you think it exemplifies strong critical thinking skills. Post a link or reference information for that source, describe the content, and explain how it is a good example of critical thinking.Search the Internet, media, or the Ashford University Library and find an example that lacks good, careful (critical thinking). Post a link or reference information for that source, describe the content, and explain why you think it demonstrates poor critical thinking skills.Support your claims with examples from required material(s) and/or other scholarly sources, and properly cite any references.Your initial post should be at least 250 words in length.

She/he started with 7.2 g of starting material and obtained 4.8 g of product.Assuming Benzoic Acid is the limiting reagent; calculate the theoretical and percent yields. Show the equation and all steps of your calculations.(Chemfinder.com and www.sigmaaldrich.com are good resources to find molecular weights and densities etc.),
Food Ingredients
How you understand food ingredients?,"According to the definition of food additives, food additives are substances added to food to preserve flavor or enhance its taste and appearance. Some additives like salting have been used for centuries. The functions of food additives is to improve the food color, taste and longer shelf life of synthetic or natural substances extracted from plants and animals. Now at the mention of food additives, many can't help but fear in the mind, they think once eat foods containing food additives will harm to health. So how do the facts? How should we treat food additive or food ingredients?what is food additive? Food additives already been parts of our life. What are food additives? Whatever a food in your hand, a large part of food ingredients are the most common food additives, such as bleaching, colouring agents, food additives emulsifiers, preservatives, potassium chloride food additive. propylene glycol food additive, lactic acid food additive, etc. Since it contains so many kinds of food additives, does that mean the food we should not to buy? The advantages of food additives is cheap and convenient to get. From the examples of food additives, common food acids include vinegar, citric acid, tartaric acid, ascorbic acid, malic acid, fumaric acid, and lactic acid are added to make flavors ""sharper""; colorings are added to make food look more attractive; preservatives food additives prevent or inhibit spoilage; antioxidant vitamins act as preservatives; gluten free thickeners for the people who have food additives allergy to gluten.Each additive is assigned a unique number, that is E number, which is used in Europe for all approved additives. For example, we can see e100 food additive, e262 food additive, food additive 330, food additive 621, etc. According to E-407 you will get it is carrageenan food additive. whether artificial food additives are good or bad, people have different views. Such as artificial food dyes have stable color low costs. Food grade food colouring additives are widely used in food and beverages, the processing of a piece of cake may need green food colouring, red food colouring, black food colouring, white food colouring, etc. Whether food dyes in food ingredients is health and no toxic？ Where to buy safe food ingredients? How to find reliable food additive suppliers or manufacturers? Many China food company are good choices and qualified.
