-Design an experiment relating to or utilizing the concepts of stoichiometry.
-Stoichiometry is the study of the quantitative relationships between reactants and products. You can calculate or predict the amount of reactants needed or product will be produced from a balanced equation with some known quantitative physical properties. Stoichiometry was first introduced to chemistry by Jeremias Benjamin Richter from Germany in the late 18th century. Richter carried out some of the earliest determinations of the quantities by weight of acid-base saturation and determined that it would take equivalent amount of different bases to saturate a particular acid of the same quantity. This concept has made important contribution to chemistry.
-Magnesium reacts with hydrochloric acid. If you increase the amount of magnesium added to hydrochloric acid will it change the mass of the initial product? Hypothesis
-If you increase the amount of magnesium added to hydrochloric acid then it will increase the amount of mass of the initial product.
-Independent Variable: amount of magnesium.
Dependent Variable: the mass of the product of magnesium added to hydrochloric acid.
Control: the amount of hydrochloric acid in each trial.
-The materials used in this experiment were test tubes, a beaker, a scale, goggles, stop watch, magnesium, and hydrochloric acid.
-Before starting the lab you need to get the following materials: test tubes, a beaker, a scale, goggles, stop watch, magnesium, and hydrochloric acid. Weigh the empty individual test tubes.
Step 1- put 1 gram of magnesium into a test tube.
Step 2- add 10mL of hydrochloric acid to the test tube.
Step 3- wait 30 seconds for the reaction to be completed with the stop watch.
Step 4- weigh the new product on the scale.
Step 5- subtract the weight of the beaker from the beaker and new product in...
