Write a purpose statement and outline of the procedures for this lab on and attach it to the back of this handout. you should not copy verbatim the procedures but rather paraphrase them in your own words and include all specific types of equipment and their parameters (i. e. 100 ml graduated cylinder) in addition to all mathematical equations to be used. a purpose statement clearly and concisely describes the goal of the experiment including the general method that will be used to meet this goal. don't resort to stock phrases; be somewhat creative. do not use the words "i, we, you, the students". do not write a pedagogical purpose. the pedagogical purpose of an exercise is not the same as the statement of purpose so statements like "we will learn" should not be included. for example, the pedagogical purpose of a lab investigating the properties of oxygen is to learn about chemical reactions and physical and chemical properties. but your statement of purpose might read "chemical properties of oxygen will be determined by carrying out reactions with sulfur, phosphorus, magnesium, and iron." you should be able to use your outlined procedure to complete the lab without using this handout. attach the purpose and outline of the procedures to this lab and bring to class on the day of lab. (you will do this for every lab) separate sheet of paper c a 2. (2 pts) is the mass of all pennies the same, regardless of age (year of mint)? record a hypothesis (prediction plus an explanation for your prediction)

If a polyatomic ionic compound has gained two hydrogen ions, then how does its name begin?

Mike and mitchell decide to have a foot race. they mark off a stretch of 100 yards, and recruit cindy to work the stopwatch. after running the race and looking at the results, cindy declared that mitchell was the fastest. so how did the boys times compare?

Predict the products of the following acid-base reactions, and predict whether the equilibrium lies to the left or to the right of the reaction arrow. part ao2-(aq)+h2o(l)< => express your answer as part of a chemical equation. identify all of the phases in your answer. o2-(aq)+h2o(l) < => oh-(aq)+oh-(aq)part bpredict whether the equilibrium lies to the left or to the right of the equation in previous part. h2o is a stronger acid than oh–, so the equilibrium lies to the right. h2o is a weaker acid than oh–, so the equilibrium lies to the left. h2o is a stronger acid than oh–, so the equilibrium lies to the left. h2o is a weaker acid than oh–, so the equilibrium lies to the right. part cch3cooh(aq)+hs? (aq) < => express your answer as part of a chemical equation. identify all of the phases in your answer. ch3cooh(aq)+hs-(aq) < => h2s(aq)+c2h3o2-(aq)h2s(aq)+c2h3o2-( aq)part dpredict whether the equilibrium lies to the left or to the right of the equation in previous part. ch3cooh is a weaker acid than h2s, so the equilibrium lies to the right. ch3cooh is a weaker acid than h2s, so the equilibrium lies to the left. ch3cooh is a stronger acid than h2s, so the equilibrium lies to the right. ch3cooh is a stronger acid than h2s, so the equilibrium lies to the left. part eno2-(aq)+h2o(l) < => express your answer as part of a chemical equation. identify all of the phases in your answer. no2-(aq)+h2o(l) < => part fpredict whether the equilibrium lies to the left or to the right of the equation in previous part. hno2 is a stronger acid than h2o, so the equilibrium lies to the right. hno2 is a weaker acid than h2o, so the equilibrium lies to the left. hno2 is a stronger acid than h2o, so the equilibrium lies to the left. hno2 is a weaker acid than h2o, so the equilibrium lies to the right.
