Title: Surface Area vs. Rate of Reaction Research question: How can different temperatures affect the rate of reaction‚ when the reactant is in powder form? Hypothesis: If the temperature of the water is increased‚ the rate of reaction will also increase as the heat given off to the particles will increase leading to more movement and frequent collisions. Background information: Chemical reactions occur when two or more molecules interact with each other‚ but that can only occur when they

Reaction paper on the article “Families” by Dr. Michael L. Tan First of all if I may‚ the article should have been entitled “Same Sex Marriage”‚ well that’s just my opinion.

Response 1. What are your feelings after watching this candid documentary? A: I had a mixture of feelings. First‚ as an American‚ I thought that the entire piece was trash and clearly had an agenda.
