For the equilibrium H2(g)+ CO2(g)<--> H2O(g)+CO(g)Kc=3.18 at 1106K. If each of the four species was initially present at a concentration of 3.000M, calculate the equilibrium concentration of the CO(g) at this temperature.
You have pure beta-D-glucopyranose of 100 grams nearly, it was dissolved in an ethanol/water combination with the intention to recrystallize the sugar. You get pure beta-D-glucopyranose crystals 60 grams back why this 40% loss was to happen.
C2H4 + 3O2 = 2CO2 + 2H2O if you start with 45 grams of ethylene (C2H4), how many grams of carbon dioxide will be produced.
If ΔH = -60.0kJ and ΔS = -0.200kJ/K , the reaction is spontaneous below a certain temperature. Calculate that temperature. Express your answer numerically in kelvins.
What amount of energy is required to completely ionize 29.9 grams of carbon atoms in the gas phase (C(g)) if the ionization energy of C(g) is 1086 kJ/mole.
Calculate the number of bromine molecules present in the flask if A flask contains 0.350mol of bromine, Br2 in liquid form .

In a calorimeter, 100 g of ice melts at 0oC. The enthalpy of fusion of the ice is 334 J/g. How much heat was absorbed.
Explain what it means that the atomic mass of naturally occurring Ag, is a mixture of its two isotopes forms, is 107.868 u.
2 NO(g) + O2(g) 2 NO2(g) In one experiment 0.633 mole of NO is mixed with 0.354 mole of O2. Calculate also the number of moles of NO2 produced.
Explain how does unique physical and chemical properties of water contribute to significance of water for life on Earth to survive.
Analysis of the products revealed two methylated sugars: 2,3,6-tri-O-methyl-D-glucose, 2,4-di-O-methyl-D-glucose and 2,3,4,6-tetra-O-methyl-D-glucose. The ratio of these sugars was 20:1:1. determine the structure of the polysaccharide?
