What will be the final temperature of the water in an insulated container as the result of passing 5.00 g of steam [H2O(g)] at 100.0°C into 195.0 g of water at 20.0°C? (?H°vap = 40.6 kJ/mol H2O) The best way to do these problems is to make the heat gained...

? [H3O+] in 0.15 M C2H2H8 and 0.35 M C2H2H9Cl

Re-post ? [H3O+] in 0.15 M C2N2H8 and 0.35 M C2H2H9Cl; Kb= 4.7 x 10^-4

Calculate the equilibrium constant at 25 C for CH4 + 2 H2O --> CO2 + 4H2 given: delta G for CH4 = -50.81 H2O = -228.6 CO2 = -394.4 H2 = 0

Could you show me how to do these math systems and show your work so i understand how to do them. 1) 3x+2y+4z=19 2x-y+z=3 6x+7y-z=17 2) 5x+8y+6z=14 2x+5y+z=12 -3x+6y-12z=20 3) x^2+2xy-2y^2=-11 x^2+xy-2y^2=-9

I. balanced equation: Ca(HCO3)2 + HCl ->CaCl2 + 2 H2O + 2 CO2 II. find moles of Ca(HCO3)2 : 40.3 mL x 1 L/1000mL x 0.2 mole/L = 8.06 x 10^-3 moles Ca(HCO3)2 III. find moles CO2 : [8.06 x 10^-3] moles Ca(HCO3)2 x 2 moles CO2/1 mole Ca(HCO3)2 = 1.61 x 10^-2...

thank you daniel!!

no one has the answer?

listen to ugmw, i was the test dummy.

e is right don't listen to bot!!!!!!!!!!
