techniques involved in this lab will be using various amounts of substance and periods of time in between weighing the product. These techniques will be tested with the reaction between vinegar (a mixture of acetic acid and water) and a solution of baking soda (a basic compound also known as sodium bicarbonate). Vinegar is a dilute solution of water and usually about 5% acetic acid‚ a colourless‚ strong-smelling carboxylic acid composed of a methyl group attached to a carboxyl group. Baking soda is a

Biology 10 Vinegar Eel Lab Adam Dorner 1) The most toxic metals were silver‚ lead and iron‚ all killing the eels in under four minutes‚ with silver taking only 1 minute and 40 seconds to kill the eels‚ and only 13 seconds to make the eels stop forward motion. Strontium wasn’t effective as after 5 minutes of exposure to it‚ the eels hadn’t died or stopped forward motion. 2) a) The accepted toxicity varies from metal to metal. The accepted toxic level of lead is 0.0012 parts per million‚ however

Gonen Galor Battery Essay Batteries have proven to be the core of modern day technology‚ without batteries modern day technology and some electronics would have never existed. Nations that invest more in battery run technology tend to have a higher labor productivity rate. This is because battery powered electronics increase could potentially increase the productivity rate of labor and thus an increase in capital goods. Electronics have also been seen as the driving force of emerging economies
