How many mL of Br2 (l) with a density of 3.12 g/mL must you dispense to have 1.56 mole (mol) of Br2 (l).
Calculate the temperature of the system once equilibrium has been reached. Assume that Cp,m for Au and H2O is constant at its value for 298K throughout the temperature range of interest.
Determine the molality and molarity of a solution made by dissolving 445 g of NaBr in 2600 ml of water ?
A calorimeter that contains 2500 g of surrounding water is used to measure the heat associated with the reaction of 520 g of a reactant. Calculate the energy, in joules per kilogram of reactant, associated with the reaction
Ethanol (molar mass = 46 g/mol) can be dehydrated to yield ethene (molar mass = 28 g/mol) by heating it with an excess of concentrated sulfuric acid (acting as a catalyst). CH3CH2OH CH2=CH2 + H2O If 23.3 g of ethanol produced 12.5 g of ethene
Is ethanol(CH3OH) a bad leaving group. Also is (CH3)2N- a bad leaving group? the Nitrogen has two methyl groups and negative charge
What is the maximum number of unpaired electrons an atom can have in this series? Will thsi be a new record for atoms in the periodic table?
earlier, lower-energy TS. Can model reaction coordinate as inverse parabolic potential well. What happens when we make X a better leaving group? Model by tilting entire plot forward. What happens when we make X a better leaving group?
What is the hydronium ion concentration of a 0.20 M solution of an acid with a Ka
What are the spectator ions in the solution after the complete neutralization reaction occurs when mixing the strong base NaOH
explain the mechanism of reaction so I understand the reason behind it. Secondly, would the iron chloride undergo syth. as an uncatalized reaction as it acts as an idicator?
A compound is found to contain 10.37 % phosphorus, 4.689 % nitrogen, and 84.95 % iodine by weight. What is the empirical formula for this compound
An experiment requires 45.8 g of ethylene glycol, a liquid whose density is 1.114 g/mL. Rather than weigh the sample on a balance, a chemist chooses to dispense the liquid using a graduated cylinder.
