Investigating Factors That Affect Rates Of Reaction Aim: How does the mass of calcium carbonate affect its rate of reaction with hydrochloric acid? Hypothesis: I hypothesize that when the mass of the calcium carbonate increases‚ the rate of reaction of the calcium carbonate and hydrochloric will also increase. The collision theory states that the more successful collisions there are within the reaction‚ the faster the rate of reaction. When the mass increases‚ so does the number of particles

POLLUTION!!- IS THERE A SOLUTION? Human Beings belong to a species that poisons its own habitat. If we think of our planet as a spaceship then we are the new and all other species are passengers. In general we behave irresponsibly .Earth’s atmosphere forms a protective cocoon around our spaceship‚ storing and recycling essential elements such as carbon and oxygen. Humans fill the air with pollution that turns the rain acidic and threatens to alter the climate pollution from and fossil and nuclear

Problems and Issues Shawn L. Porter HUM/111 June 09‚ 2013 John Quesnel Problems and Issues I have been considering to end my relationship for months now because of what I considered to be multiple problems. After reading chapters 7 and 8 of our text I have come to realize that there are problems and issues in this relationship. Problems that we can solve if we take the appropriate actions‚ and issues that can be resolved if we can come to a mutual agreement. I now see that our problem is

Find unresolved problems from the customer’s stand- point and resolve them without overshooting. Use “associationalthinking” by finding similar solutions to other problems to apply to your niche.

BUFFER SOLUTION (ACID) An acidic buffer solution is simply one which has a pH less than 7. Acidic buffer solutions are commonly made from a weak acid and one of its salts - often a sodium salt. Objectives: 1. Measure the pH of the unknown solution first with indicators and then with pH paper. 2. compare the buffer solution with both a strong acid and a weak acid materials: 2 30 mL beakers 2 100mL volumetric flask 1 10mL pipet 2 aspirator 1 50mL graduated cylinder 1 10mL graduated
