2HBr(g) ? H2(g) + Br2(g)
Initially a container contains 0.75 M HBr and no product. What is the equilibrium concentration of HBr if the equilibrium concentration of H2 is 0.14 M?
Glycerol, C3H8O3, is a water-soluble liquid of density 1.2656 g/ml at 15oC. Calculate the molarity of a solution of glycerol made by dissolving 40.000 ml glycerol at 15oC in enough water to make 250.000 ml of solution.
Give the systematic names for the formulas, or the formulas for the names. (Type your answer using the format copper(II) chloride for CuCl2, and using the format CO2 for CO2. Omit the centered dot for hydrates.) (a) NaNO2 (b) tin(IV) chloride (c) ..

The temperature of 55.6 grams of a material decreases by 14.8 degrees C when it loses 3080 J of heat. What is its specific heat?
what is the difference between a 10% (v/v) methanol (CH3OH) solution and a 10%(m/m) methanol solution
Explain which of the following choices has the compounds correctly arranged in order of increasing solubility in water?
CsCl crystallizes in a unit cell that contains the Cs+ ion at the center of a cube that has a Cl- at each corner. Each unit cell contains __________ Cs+ ions and __________ Cl-, ions, respectively.
why we call benzene phenyl and not benzyle when one hydrogen is removed because in case of alkanes we name them alkyl on the removal of one hydrogen atom.
Consider a system with four energy levels: 0E, 1E, 2E, 3E, where E is 100K * k (E represents epsilon and k is Boltzmann's constant). Assume that there are 10 particles.
If you start with 15.0 of a 0.900 solution of , and then dilute it with water to 270 , what is the concentration of at equilibrium?
A stream of humid air containing 1.00 mole% H2O(v) and the balance dry air is to be humidified to a water content of 10.0 mole% H2O. For this purpose, liquid water is fed through a flow meter and evaporated into the air stream. The flow meter, R, ..
A voltaic cell consists of a Zn/Zn2+ half-cell and a Ni/Ni2+ half-cell at 25 ?C. The initial concentrations of Ni2+ and Zn2+ are 1.50M and 0.100M , respectively. The volume of half-cells is the same.
