chemistry
H2 + CO2 <--> H2O + CO if there were something that were added to this system to absorb the CO2, where would the equilibrium shift? Please don't just give the answer, explain as well, thanks :)

chemistry
that makes sense, thanks for your help

chemistry
I think the question was asking for the Cl (aq) ions

chemistry
NaCl(s) + H2O(l) <--> Na(aq) + Cl(aq) If you added chloride ions to the above equilibrium, what would happen to the concentration of the products, and the concentration of the reactants? I know the equilibrium would shift to the left, and I am guessing the concentration ...

Math
30?

chemistry
For the reaction CO2 + H2 <--> CO + H20 + heat, indicate how the change in condition will shift the equilibrium (ie right or left) a. Removal of CO2 b. Addition of H2 molecules c. Increase volume of reaction vessel d. Addition of catalyst e. Refrigerate reaction vessel

aig math
Pat= x , Kyle= y, Ryan= z x+y+z= 306 2x= y+z z+18=y So from here, you just plug the equations into each other... 2x= y+z so, 2x= (z+18)+z so, 2x= 2z+18 so, x= (2z+18) /2 Then you plug this in to the equation: x+y+z= 306 So... (2z+18) /2 + (z+18) + z = 306 Then, 4z+38 = 612 4z ...

aig math
so just do this... 8x+6x+9x then you know that 8x+6x= 84 so, 14x=84 so, x=6 then you multiply 6 by 9, and your answer is 54 marbles

chemistry
Thanks so much! :)

chemistry
At a certain temperature, the concentrations of NO and NH3 are equal, and the concentration of H2o and o2 are 2.0M and 3.0M respectively. What is the value of Keq at this temp? The equation is 5O2+4NH3--> 4NO+6H20
