A physical change can alter the state of matter‚ but not the substances identity. A chemical change transforms a substance from one identity to another. It is important to identify the difference between physical and chemical changes in any lab because you want to know the process of what is going on. The first experiment was the water jug explosion

Introduction: A balanced chemical equation has reactants and product that has to represent a formulae. The amount of each element‚ number needs to be the same in either side of the equation. (E.g.‚ HCl(aq)+NaHCO3(s) reacts to produce NaCl(aq)+H2O(I)+CO2(g)‚ this is the equation given for this lab). This help us view the study of Law of Conservation of Mass‚ when either side of equation is equally balanced. The calculation for formula mass helps determine if you need to convert grams to a particular

In the past few years‚ I used agave syrup or nectar in several recipes before I heard some negative things about it. I have looked at where agave comes from‚ the chemical composition‚ how it is metabolized‚ calorie content and what it may be used for.
