O C R2 R1 O R2 + H O H acid alcohol ester water Here R1 and R 2 represent groups such as CH3 - or CH3 CH2 -. The reaction type shown above may be called a condensation reaction because the small molecule H 2 O is eliminated from the reactants while the remaining bits of the reactant condense together to give the main product. This reaction may also be called an esterification‚ since the product of the reaction is an ester‚ a compound containing the CO2 R group (see chapter

The Bandura et al experiment in 1961 conducted research into how we can transmit aggression through imitating aggressive models. 36 boys and 36 girls aged between 37 and 69 months were subject to this experiment. There were 3 conditions‚ the control group‚ the group exposed to the aggressive model and the group exposed to the passive model. In the standard condition‚ a child was settled in a corner with a small table and chair‚ potato prints and picture stickers. An adult model was then escorted

Is it normally acceptable to experiment on non-human animals to develop products and medicines that benefit human beings? New scientific research has cast grave doubt on the safety testing of hundreds of thousands of consumer products. Everyday products‚ from soft drinks to paints‚ contain numerous synthetic chemicals. Official assurances of the safety of these chemicals are based largely on animal experiments. But recent results from a consortium in America suggested such assurances may be worthless

The purpose of this experiment was to test the tonicity of potato cells. The potato cells were placed in different test tubes with water and were left there for 15 minutes. The percent change in mass is then used to determine if the cells lost or gained water‚ therefore determining the tonicity of the cell. Although it was a brief short time‚ the final results showed that the more water the potatoes were placed in‚ the more hypotonic the potato becomes. Tonicity is stated to be the state of a solution

You’ve probably heard of "fair trade coffee‚" but may not be quite clear on what it actually is. It refers more to a practice than a type of coffee‚ and the emphasis is definitely on the word "fair."
