Pre lab example

Suggest two sources of error related to the data you collected that would have caused these experimental results. Data: If the laboratory report is handwritten use a ruler to draw data tables and graphs! Related documents. There were 2. By knowing the mass of the Sn reacted in the experiment and the mass of the oxygen in the product, we were able to determine the empirical formula of the product by converting these masses to moles and then dividing the greater mole quantity by the lesser. This is the most important part of the carefully! Always include units with all data entries. It is highly recommended that you use graph or engineering bond paper for written reports. Record the information from the experiment in the table while conducting the lab. Keep it in your chemistry notebook. Procedure: Each step of the procedure must be written here. A person who understands chemistry should be able to read this section and know what you are doing. Reagents: A listing of chemicals used in the experiment with their amounts and any warnings. The hypothesis explains what is to be tested and will be written after reading the entire laboratory worksheet.

State whether the results were too high or too low. Obvious calculations such as addition and subtraction need not be included. Show work for calculations, express all answers to the correct number of significant digits and include units.

Always use graph paper, and be sure to label all axes with names and units, and give each graph a title. Data: If the laboratory report is handwritten use a ruler to draw data tables and graphs!

All chemistry lab reports must be written neatly and well organized to receive full credit. You may paraphrase and shorten the explanations, but the reader must be able to perform the experiment from these instructions.

There were 2. Drawings of the experimental setup may be included here. Related documents. Do not erase when recording data; simply draw a single line through a mistake and record the new value next to it.

There should be a whole number ratio between oxygen and tin. Also, any special circumstances or problems with the experiment are stated here.

Pre lab definition

Include all units in all calculations; be sure to show how they cancel. The teacher may make changes to the procedure; make sure that you write any changes down! Solve any problems showing all work and with the correct number of significant figures. Reagents: A listing of chemicals used in the experiment with their amounts and any warnings. Also, any special circumstances or problems with the experiment are stated here. The hypothesis explains what is to be tested and will be written after reading the entire laboratory worksheet. Do not include lengthy, detailed directions. This is the most important part of the carefully! It is highly recommended that you use graph or engineering bond paper for written reports. State whether the results were too high or too low. You may paraphrase and shorten the explanations, but the reader must be able to perform the experiment from these instructions. By allowing the nitric acid to react with the granulated tin metal we were able to produce a tin-oxygen product called tin X oxide. In quantitative labs, an error statement with possible sources of error is necessary. Always use graph paper, and be sure to label all axes with names and units, and give each graph a title.

Hypothesis: If nitric acid is poured onto tin, a tin oxide will be produced. This is the most important part of the carefully!
