Do not use staples, paper clips, highlighters, glue or correction fluid.
Chemical reactions, and Equations Materials: Wear aprons and goggles. Protective gloves are also available. Carefully read the labels of all chemicals before use. Abide by specific warnings and directions. Collect all materials needed for a procedure before proceeding.
Perform reactions under the hood when directed. Chemicals may be weighed and prepared at balance or lab tables, but tests should be carried out under the hood. Acids and caustic chemicals are stored in the hood. Please do not take these chemicals from the hood. Metathetical reactions Precipitation reactions A1.
Add a dropperful of 0. Feel the test tube. Can you detect the evolution of heat? Place a spatulaful of sodium carbonate in a test tube. Add a dropperful of 1. Redox Reactions Combination reactions A1. Work under the hood! With a pair of tongs, hold a strip of magnesium in a bunsen burner flame.
Do not look directly at the flame. Save the ash in a small beaker for the next procedure.
If magnesium is substance "A" in the general equation, what is "B"? Add a dropperful of distilled water and a drop of phenolphthalein. The phenolphthalein is only an indicator for the presence of hydroxide ion and does not enter into the equation. Weigh out exactly 0.
Clamp and warm gently with a Bunsen burner.IB Chemistry - Internal Assessment Lab Format The following titles and subtitles should be used for your lab report and given in this order within your lab report. Use the following sheet as a checklist when writing lab reports.

I have an ImageSpan inside of a piece of text.
What I've noticed is that the surrounding text is always drawn at the bottom of the text line -- to be more precise, the size of the text line grows with the image but the baseline of the text does not shift upward.
The specific problem is: After several splits from the Deepwater Horizon oil spill/Health consequences of the Deepwater Horizon oil spill articles, this article may contain information which is duplicated in the different sections. It also needs a proper restructuring.
