Chemical Equilibrium ------------------------------------------------- ------------------------------------------------- RESULTS AND DISCUSSION A. Iron-Silver Equilibrium In studying equilibrium between iron and silver‚ 0.10 M FeSO4 and 0.10 M AgNO3 were used. The balanced equation for the reaction is: FeSO4 (aq) + 2 AgNO3 (aq) ↔ Fe(NO3)2 (aq) + Ag2SO4 (s) It has a net equation of: Fe2+(aq) + Ag+(aq) ↔ Fe3+(aq) + Ag(s) This part of the experiment

Experimental Procedure and Interpretation of Data Collection and Preparation of Materials The bark of Santol (Sandoricum koetjape (Burm.f.) merr.) were collected at the researchers backyard on Rosales‚ Province of Pangasinan. The collection was done in the month of August to September 1999. The bark was collected through the used of a knife. The bark were dried under the sun. And were placed into container and tightly closed ready for expression. Preliminary Test for the Determination of Plant

Experimental Research PSY/285 I have chosen to describe the study to be performed by the pharmaceutical company that wants to test a new sleep aid. Before they engage in human studies the researchers must determine what they want to prove exactly. Since the goal of the drug is to promote better sleep habits‚ the hypothesis for this study would be that individuals taking this new aid will fall asleep faster and stay asleep longer than they did before they started taking the drug

Lab 3: Experimental Design & Hypothesis Testing 1. Some observations found about termites are that they live in moist‚ dark environments‚ they are sterile and lack eyes‚ and their primary task is to collect food. From this information the hypothesis that due to their lack of eyes‚ they use feeling of their skin to find what they are searching for and a pencil line would give a feeling of wood that would attract the termites. By making a course that split into two paths of a pen line and pencil line

EXPERIMENTAL ESTIMATES OF EDUCATION PRODUCTION FUNCTIONS* ALAN B. KRUEGER This paper analyzes data on 11‚600 students and their teachers who were randomly assigned to different size classes from kindergarten through third grade. Statistical methods are used to adjust for nonrandom attrition and transitions between classes. The main conclusions are (1) on average‚ performance on standardized tests increases by four percentile points the first year students attend small classes; (2) the test score

A.N.Z.J. Fam. Ther.‚ 2000‚ Vol. 21‚ No. 2‚ pp 73±80 Counselling and Psychotherapy: Is There a Difference? Does It Matter? Hugh Crago* The terms `counselling ’ and `psychotherapy ’ are often employed in a loosely interchangeable way‚ especially in Australia. Where distinctions are made‚ there has been little agreement on what each term should cover. This article examines several axes on which `counselling ’ might potentially be distinguished from `psychotherapy ’; the most promising basis

Doctors perform surgery on someone in an effort to make them feel better or learn a little more about their condition. When scientists and doctors try new things they usually try them on animals‚ studying the results‚ heightening their techniques‚ and exploring new ways to heal people. But sometimes doctors are put on the spot‚ so they have to take action or someone will be seriously hurt. Experimental
