correctly for #2 is 98.25
I hope this will help us figure out now For questions #1 through #10, refer to the following equilibrium system, with a Kc of 1.23E-03: C3H6O (aq) + 2C2H6O(aq)----> C7H16O2 (aq) + 2H2O (l) 1. What is the equilibrium expression for this system? [C7H16O2]/
DID I DO IT RIGHT NOW 1.M=6.55*1mol/101gn=.065 .065/250=.260 2.m=6.55g*15.0=.89 so this mean I need to use the full 250ml 3.6.55/250*100=2.62
I have to use the equation above:following equilibrium system with a Kc of 1.23E-03: C3H6O (aq) + 2C2H6O (aq)--> C7H16O2 (aq) + 2H2O (l) to complete the problems..this is what my teacher gave me to go on..So can u please help me out.. Tell me if I am go in
This is what I did..please check it 1.P1V1=P2V2 P=6.55/250=.0262 2.V=P*V1/V2 P=6.55*15.0/250=.393 3.P=PV2V PP=6.55/250=.0262
Plese check: thank u. 1.[C3H6O][C2H6O]2/[C7H16O2][H2O]2 2.8.00E-05
can you check to see I did it right. 1.[C3H6O][C2H6O]2/[C7H16O2] 2.2.04E-06
I am try to follow the example but lost.. cant figure out how they got that 420
unbalanced chemical reaction equation: CaCl2 (aq) + b Na3PO4 (aq)----> c Ca3 (PO4)2(s) + d NaCl (aq) iF I start with 3.50 g calcium chloride (and sufficient sodium phosphate), what is my theoretical yield of calcium phosphate?
I AM STILL CONFUSE..FOR THE FIRST I CAME OUT WITH .40 BUT FOR NUMBER 2 I STILL CAN FIGURE OUT THAT ONE..PLEASE HELP
You have a 4.0 L steel tank containing hydrogen gas. You are able to heat or cool the tank and meaurse the pressure of the gas. 1.If the temperature is 25degree and the pressure is 3.5 aim ..How many grams of hydrogen does the tank contain. 2.at what
