For another picnic you want to make hamburgers with pickles, again without having any left over. You need to balance the number of packages of buns (which usually contain 8 buns) with the number of packages of hamburger patties (which usually contain 12 patties) and the number of jars of pickles (which contain 18 slices). Assume that each hamburger needs three pickle slices. What is the smallest number of packages of buns, packages of patties, and jars of pickles, respectively? Express your answer as three integers separated by commas.
You have 500.0 mL of a buffer solution containing 0.20 M acetic acid (CH3COOH) and 0.30 M sodium acetate (CH3COONa). What will the pH of this solution be after the addition of 20.0 mL of 1.00 M NaOH solution? [Ka = 1.8 ´ 10-5]
Why would climate change relate to this or better said how would increased levels of carbon dioxide in the air affect these underwater organisms? Draw a set of equilibrium equations
determined the limiting reactant and the theoretical yield (in g) of nitrogen that can be formed from 24.0 g N2O4 and 23.5 g N2H4 molar masses are as follows: n2o4 92.02 n2h4 32.05
Which metal is associated with the synthesis of cyclopropanes?
A 29.0-g sample of water at 260. K is mixed with 48.0 g water at 300. K. Calculate the final temperature of the mixture assuming no heat loss to the surroundings.
Determine the value of the equilibrium constant at this temperature - Ammonium Hydrosulfide NH4HS yields NH3(Ammonia) and Hydrogen sulfide
The decomposition of N2O into N2 and O in the presence of gaseous argon follows second order kinetics with K= (5.0x10^11 Lmol^-1s^-)e^-29000K/T. What is the energy of activation of this compound
Write the total ionic equation for this reac- tion occuring in water: Calcium sulfide and iron(II) bromide are mixed to form iron(II) sulfide and calcium bromide.
NH3(Ammonia ) is widely used in many household cleaners and as a fertilizer. Calculate How much ammonia (in units of mol) is produced when 7.8 mol of H gas react with an excess of N gas.
Calculate What will be the volume of this gas sample at standard atmospheric pressure and
Determine the new volume of the mixture if the constant is kept constant at 635 mmHg and all the energy released is converted to work to push the piston.
What is it about the structures of poly(acetylene) and poly(p-phenylenevinylene), and not poly(1-butene), that allows these polymers to conduct electricity? Use discussions of hybridization, pie bonding, and resonance as the basis for your argumen..
