Hydrogen can be extracted from natural gas according to the following reaction: CH4(g)+CO2(g)<-->2CO(g)+2H2(g) Kp=450 at 825K An 85 L reaction container initially contains kg of CH4 and 55.4 kg of CO2 at 825 K Assuming ideal gas behavior, calculate the mass of H2 in grams present in the reaction mixture at equilibrium.
0.60 g of hydrogen chloride HCl is dissolved in water to make 7.5 L of solution. What is the pH of the resulting hydrochloric acid solution.
The work function for Cu metal is 4.80 eV. If a piece of Cu is bombarded by violet light (λ = 4,000 Å), will electrons be ejected? "YES" or "NO" with supporting argument/calculation.
Explain how do you compute the minimum volume of H2O(water) required to dissolve NaCl( sodium chloride) of 500 grams in H2O( water) at the temperature of 100 degree celsisu?
What are the n and l quantum numbers of the electron removed when Bi is ionized to Bi+ and would you expect element 115 to have ionization energy greater than, equal to, or less than that of bismuth? Explain.
How much heat is lost when a 640 g piece of copper cools from 375 oC, to 26 oC? (The specific heat of copper is 0.387 J/g . oC)
If 3.1 mol of ethane (C2H6) undergo combus tion according to the unbalanced equation C2H6 + O2 -! CO2 + H2O, how much oxygen is required?
