Aluminum metal displaces chromium from a solution of 0.2 M chromium (III) nitrate. Write an activity series, most active to least active, based on this data.
solving this question helps the student to understand how to find the limiting reactant and how much product is
How would the rate of disappearance of ethyl bromide change if the solution were diluted by adding an equal volume of pure ethyl alcohol to the solution? The reaction between ethyl bromide (C2H5Br) and hydroxide ion in ethyl alcohol
determine that the metal ion was a +2 ion, then which metal is it? This metal was used in batteries for a long time (even in "alkaline" batteries) due to its good electrochemical properties, but it is now being phased out. Why?
A student ran the following reaction in the laboratory at 689 K H2(g) + I2(g) 2 HI(g)
Helium-oxygen mixtures are used by divers to avoid the bends and are used in medicine to treat some respiratory ailments. What percent (by moles) of He is present in a helium-oxygen mixture having a density of 0.508g/L at 25C and 721mmHg?
Sort the subsequent reactants into one of these three categories- arrhenius/bronsted- lowry acid, arrhenius base, bronsted- lowry base, based upon their actions in the reactions shown
A cleaning solution is found to have a [OH-] = 3.2 x 10-12M. What is the [H3O+] and is the solution acidic or basic?
how many moles of H2 gas should be taken up by 1-octene in course of this reaction. What volume does this correspond to at STP.
A voltaic cell is constructed by immersing a strip of silver in a 1.0M AgNO3 solution and a strip of cadmiun metal in a 1.0M Cd(NO3)2 solution. The circuit is completed by a wire and a salt bridge in the usual way. Write the balanced overall cell ..
There is an uncontaminated background well (Well 2) with Chloride levels at 100mg/Liter and arsenic at 0.1mg/Liter. Well 3 is located down gradient of the contaminated area with a Chloride level of 300mg/liter. If the Arsenic concentration for Wel..
Identify the better leaving group in each of the following pairs and provide a brief justification for each - provide a mechanism for the reaction
