money. This dynamic is that experiences are often shared with others; where as material possessions are more inclined to individual use. “If so‚ variations in the sociality of experiences should moderate the extent to which they provide happiness relative to material possessions. Extensive research shows that social relations are influential sources of happiness” (Caprariello & Reis‚ 2013). Therefore material possessions intended for social use may lead to greater happiness than possessions intended

when there is less starch present the intensity of the color purple decreases. The the objective of this experiment was whether the change in temperature and the speed of reactivity of amylase is directly proportional or not. The hypothesis was with the increase in temperature there would be an increase in the speed of reactivity of amylase with starch. Results showed that with the increase in temperature there is an increase in the speed but after 37ºC the rate of reaction decreased. This proved

It also has a very low reactivity. Silver is stable with both clean air and water‚ but it does have a reaction with halogens. When silver metal comes together with fluorine it reacts and creates silver fluoride ‚ the chemical formula follows‚ Ag(s) + F2(g) → AgF2(s). The reason

EXPLORATORY RESEARCH Exploratory research is conducted to clarify ambiguous problems. Management may have discovered general problems‚ but research is needed to gain better understanding of the dimensions of the problems. Exploratory studies provide information to use in analyzing a situation‚ but uncovering conclusive evidence to determine a particular course of action is not the purpose of exploratory research. Usually‚ exploratory research is conducted with the expectation that subsequent research

Responding: Gas Evolution EXPECTED RESULTS: It is expected that Calcium Carbonate would have a faster rate of reactivity when being reacted with Hydrochloric acid and have a larger measure of gas collected than the Sodium Carbonate. The gas expected to evolve from the conical flask to the gas syringe in both reactions with the compounds is Carbon dioxide. Equation

Satsatin Biology Student‚ Biology Department College of Science‚ De La Salle University-Dasmarinas ABSTRACT Five substances which are Hexane‚ Eugenol‚ Unknown hydrocarbon 1‚ Unknown hydrocarbon 2‚ and Acetylene gas was used for the selective reactivity of hydrocarbons to functional group tests; Bayer’s test‚ Bromine test light‚ Bromine test dark‚ and Tollen’s test. In Bayer’s test‚ only Acetylene‚ Eugenol and Unknown hydrocarbon 2 reacted positively and the rest retain the purplish color of KMnO4

It is somewhat ironic to discover that the pharmacophore of phosphoramide drugs currently used as antitumor agents was originally utilized for the purpose of chemical warfare‚ most prominently so in World War I. Sulfur mustard‚ the precursor to phosphoramide drugs‚ was employed to great effect as a wounding agent in the characteristic trench warfare of WWI; Being a dense gas‚ sulfur mustard settled in trenches and created persistent environmental hazards for troops. Exposure to sulfur mustard‚
