Mole Ratio of a Chemical Reaction: Copper & Silver Nitrate Lab #4 OBJECTIVE In this experiment‚ you will determine the number of moles of reactants and products present in the reaction of copper and silver nitrate‚ and calculate their mole-to-mole ratio. The mole-to-mole ratio relating to the disappearance of copper and the formation of silver metal will be used to write the balanced equation for the reaction. The reaction of copper metal with silver nitrate solution is a single

The SN2 reaction requires three qualities: a strong nucleophile‚ a good‚ unhindered leaving group‚ and a polar‚ aprotic solvent. For our reaction‚ we have all three bases covered. The nucleophile is an alkoxide‚ a deprotonated alcohol. Technically‚ because our alcohol is a phenol‚ the conjugate base is called a phenoxide. Phenol itself has a pKa of about 10‚ but our alcohol has more resonance opportunities‚ so the pKa is down around 8. This is sufficiently acidic for use of weak base like K2CO3 for

Chemical Reactions- Sodium Hydroxide A chemical reaction is a change where two or more substances are changed into a new substance. You can identify a chemical reaction by colour change‚ effervescence (bubbles)‚ when light or heat given off‚ and the change is usually irreversible. There are 6 main types of chemical reactions- combustion (often called burning)‚ synthesis‚ decomposition‚ neutralization‚ single replacement and double replacement. A combustion reaction is a reaction with oxygen‚ and

Organic Chemistry II Lab Diels Alder Reaction Purpose: In this experiment a Diels-Alder reaction was used to form the products. Cyclopentadiene and maleic anhydride were reacted together to form cis-Norbornene-5‚6-endo-dicarboxylic anhydride. 7-oxabicyclo{2.2.1}hept-5-ene-2‚3-dicarboxylic anhydride was also produced through a Diels-Alder reaction with the combination of furan and maleic anhydride. Equation: Procedure: Part 1 In a flask equipped with

compare that relative reactivity of Na and k -Sodium and potassium react somewhat similar when reacting with water however they are slightly different. Sodium moves because of the hydrogen coming off of it and has a low melting point while potassium’s reaction is faster and enough heat is produced to set light to the hydrogen coming off of it. Each leaves a pink color hue in the water. Discuss the similarities and differences in the behavior of the metals tested with water relative to their positions

Grignard Reaction: Synthesis of Triphenylmethanol Hai Liu TA: Ara Austin Mondays: 11:30-2:20 Abstract: In this experiment‚ phenylmagnesium bromide‚ a Grignard reagent was synthesized from bromobenzene and magnesium strips in a diethyl ether solvent. The Grignard reagent was then converted to triphenylmethanol‚ a tertiary alcohol with HCl. The reaction for phenylmagnesium bromide was: The reaction for Grignard to triphenylmethanol was: In the formation of the Grignard reagent

Dances with Wolves Reaction Paper Reaction or response papers are usually requested by teachers so that you’ll consider carefully what you think or feel about something you’ve read. The following guidelines are intended to be used for reacting to a reading although they could easily be used for reactions to films too. Read whatever you’ve been asked to respond to‚ and while reading‚ think about the following questions. * How do you feel about what you are reading? * What do you agree or

Internal Rate of Return In investment decision analysis you may need to calculate internal rate of return. “Internal rate of return (IRR) is the discount rate that gives the project a zero NPV” (McLaney‚ 2006). It is a good choice to use for investment projects. There is a formula for the internal rate of return: (A is the lower discount rate and B is the higher rate‚ a is the NPV at the lower rate and b is the NPV at the higher rate.) For example the Net Present Value (NPV) is 88 when the

(Interest rate parity is a no-arbitrage condition representing an equilibrium state under which investors will be indifferent to interest rates available on bank deposits in two countries.[1] The fact that this condition does not always hold allows for potential opportunities to earn riskless profits from covered interest arbitrage. Two assumptions central to interest rate parity are capital mobility and perfect substitutability of domestic and foreign assets. Given foreign exchange market equilibrium
