At equilibrium, the concentrations in this system were found to be [N2]=[O2]=0.100 M and [NO]=0.500 M. The balanced chemical equation is N2+O2<--->2NO.If more NO is added, bringing its concentration to 0.800 M, what will the final concentration of NO be after equilibrium is re-established?
Assuming the same mass of each, which of the following substances will have the highest temperature change if they all absorb the same amount of heat Gold
Neglect the absorption of other waste gas components into the water, and the evaporation of water into the waste gas stream. What rate is NH3 is being removed from the feed gas?
Three Introductory Chemistry students each measured 50.0 mL of 1.0 M NaOH into "double-walled" styrofoam cup calorimeters. Then, Sue added 50.0 mL of 1.1 M HCl to her NaOH solution
10.0 moles of NH3 and 10.0 moles of H2 are introduced into a 2.00 L flask. At equilibrium, 3.0 moles of NH3 gas remain. Calculate Kc for this reaction.
The average concentration of strontium ion in seawater is 8.00 mg of strontium ion per kg of seawater. What is the molarity of the strontium ion if the density of the seawater is 1.025 g/mL.
What one reagent should re-energize the light solution after it has faded? Explain using moles and limiting reagents.
Determine the pH of a solution containing A) neglecting activities. B) including activities The solution contains BOTH chemicals
a solution of NaOH is added to the supnatant liquid until it is strongly alkaline. No precipitate is formed. Which ions are present in each of the precipitates. Which cations are not present in the original solution?
The standard molar enthalpy of formation of ClF3 is -405 kJ. 1/2 Cl2(g) + 3/2 F2(g) → ClF3(g)
An an isothermal process, the pressure on 1 mol of an ideal monatomic gas suddenly changes from 4.00 atm to 100.0 atm at 25°C. Calculate w
Molarity is only one of many ways to express concentration. Another is percent mass per volume or %(m/v). For example, vinegar usually contains about 5 %(m/v) acetic acid(5g acetic acid/100 mL vinegar)
the freezing point (5.5 C) and boiling point (80.1 C) of benzene and the temperature difference between these points was divided into 50 units (called X), what would be the freezing and boiling points of water in X
