Enzyme lab (yeast) assessment

  1. 1. Assessment<br />Describe the odor, color, viscosity (thickness), and flammability of hydrogen peroxide.<br />What happened when you put the cork on the test tube? Explain why this happened. <br />What kind of gas was produced by this reaction? What evidence do you have to prove this?<br />What do you think was left in the test tube at the end? Describe some of its properties. Is it the same substance that you started with?<br />What role does the yeast play in this chemical reaction?<br />coefficientcoefficientExample: SnO2 + 2 H2 -> Sn(s) + 2 H2OWrite a chemical equation for this reaction, using coefficients to balance the equation if necessary.<br />What evidence do you have that this was a chemical change and not a physical change?<br />
