CHM 101 The compound methanol consists of carbon, oxygen, and hydrogen. A 5.000-gram sampl CHM 101 The compound methanol consists of carbon, oxygen, and hydrogen. A 5.000-gram sample of methanol contains 1.875 g carbon. What is the mass of carbon in a 100.0-gram sample of methanol? (This is the same as determining the mass percent composition of carbon.)The mass percent composition of an element in a compound is calculated by dividing the mass of the element by the total mass of the compound an...

Trihalomethanes - A group of four chemicals that are formed along with other disinfection byproducts when chlorine or other disinfectants used to control microbial contaminants in drinking water react with naturally occurring organic and inorganic matter in water. What are the four trihalomethanes? - Chloroform (CHCl3), Bromodichloromethane (CHClBr2), Dibromochloromethane Bromoform (CHBr3) How can one be exposed to trihalomethanes? - Drinking water Showers Swimming...

Question When making changes to optimize part of a processor, it is often the case that speeding up one type of instruction comes at the cost of slowing down something else. For example, if we put in a omplicated fast floating-point unit, that takes space, and something might have to be moved farther away from the middle to accommodate it, adding an extra cycle in delay to reach that unit. The basic Amdahl's Law equation does not take into account this trade-off. a) If the new fast floati...

Methods for Making Ethyl Ethanoate. Industrial method Ethyl ethanoate is made by esterification. A mixture of sulfuric acid, acetic acid and ethanol are heated and poured into an esterifying column. The mixture that evaporates first goes into a second column. 85% of ethyl acetate is separated. After distillation occurs, water is added. There are now two layers. T

Methods for Making Ethyl Ethanoate. Laboratory method Ethyl ethanoate is formed by pouring a mixture of concentrated sulfuric acid, ethanoic acid and ethanol into a round-bottomed flask and then placing that flask on top of an electric heater or water bath. Distillation takes place. Condensation then occurs and the ester is collected in another beaker in droplets. Ester is evaporated first because it is volatile

What are the differences between aliphatic (including alkanes, alkenes,alkynes and cyclic compounds) aromatic hydrocarbons are. - ALIPHATIC Hydrocarbon: Non-aromatic -Alkanes & CycloAlkanes:single bonds; saturated:Contain only carbon and hydrogen & C-C & C-H single bonds -Alkenes:double bond(s) -Alkynes: triple bond(s) *alkenes and alkynes are unsaturated: at least one C-C double or triple bond(s) AROMATIC Hydrocarbon: benzene ring What is the trend in solubility and boiling point/mel...
