1. Determine the order of the reaction A --> 2B + C from the following data obtained for [A] as a function of time. time | [A] | 0 min | 0.80 M | 8 mins | 0.60 M | 24 mins | 0.35 M | 40 mins | 0.20 M | ------------------------------------------------- Use diferential and half life. 2. Balance the equation below and determine the rate expression using the given data. Find k with units. N2 + H2 ---> NH3 (all gaseous) [N2] (mole/L) | [H2] (mole/L) | Initial Rate (mole/L /min)

determine the reaction time of the test participant and using the subtractive method identify the selection time and identification time of the participant. The experiments had one participant who participated in a total of 6 experiments; two experiments required a simple reaction with a single stimulus and 4 experiments that required a more complicated reaction. Keywords Subtractive method – the procedure of estimating the time it takes to perform various cognitive operations. Simple reaction – this

SN1 Reactions For SN1 reactions it’s important to have a good leaving group because this reaction occurs in two steps. Because alcohol is such a poor leaving group it needs to be helped by silver nitrate to help promote the ionization of the alkyl halide. This helps form the products of the SN1 reaction. 2-chlorobutane This reaction didn’t occur because the carbocation isn’t stable enough for an SN1 reaction. 2-bromobutane This reaction occurred in 32 seconds. This reaction occurred quickly

Aldol In this preparative lab‚ an aldol (trans-p-anisalacetophenone) was produced from the reaction between p-anisaldehyde and acetophenone with the presence sodium hydroxide. The reaction also showed the importance of an enolate and the role it played in the mechanism. Sodium hydroxide acts as a catalyst in this experiment and is chosen because of its basic conditions and pH. The acetophenone carries an alpha hydrogen that has a pKa between 18 and 20. This alpha hydrogen is acidic because of its

Properties and Reactions of Hydrocarbons Abstract Introduction Hydrocarbons are organic materials that contain only carbon and hydrogen atoms‚ these molecules can be saturated or unsaturated and acyclic‚ cyclic‚ or aromatic. In this experiment we used a variety of methods to examine the physical and chemical properties of hydrocarbons. The first experiment we tested a variety of solvents to see if they dissolved our alkane (Decalin). One would expect that non-polar solvents will dissolve

Coursework Rates of Reaction Research The rate of reaction tells us how quickly a chemical reaction takes place. It is important for people in industry to know how fast a reaction goes. They have to know exactly how much of their product they can make each hour‚ day or week. In a shampoo factory‚ the rate might be 100 bottles per minute. We can’t work out the rate of a reaction from its chemical equation. Equations can only tells us how much product we can get. They don’t say how quickly

BIOL2220 Lab 3: Hill Reaction Introduction In 1937‚ Robert Hill discovered that isolated chloroplasts can generate oxygen when they are illuminated in the presence of a suitable electron acceptor‚ even in the absence of carbon dioxide. This finding was a landmark in the study of photosynthesis because it established that the source of the electrons used in the light reactions is water. It also confirmed that the released oxygen is derived from water instead of carbon dioxide. In chloroplasts

promotes abortion because they are preventing the development of a child‚ indirectly killing it. This opposes one of the church teachings‚ one of the Ten Commandments to be exact. And also‚ I do not agree with the passing of the bill because the Philippines is a Catholic country and defying the church teachings means denouncing our faith. Despite these circumstances‚ the president still agreed to this. They think that approving the RH bill can help lessen the over population and the decreasing of resources

Philippine Government Bureaucracy Submitted by: Judd Danielle Y. Garcia A75 / ACT143 Submitted to: Mrs. Maria Diana Dela Vega Malayan Colleges Laguna SUMMARY According to Max Weber‚ Bureaucracy is a distinct form of organization that is ideal for the government. It is structured by hierarchy of offices. These offices are ranked in a hierarchical order and their operations are characterized by impersonal rules. Each office has its own task in which they follow the rules
