**chemistry**

say A -> B + 5kJ would reactants have more enthalpy or products have more enthalpy? I think first, the delta H would be negative. So H final must be less than H initial. So reactants have more enthalpy?

**chemistry**

Is there a salt bridge in a fuel cell? I think there isn't one because hydroxide ions and hydrogen ions are in the water, so they can move around freely already.

**physics**

They all have values around there, so I'm sure the proportionality is something like that. But I'm supposed to graph it to show this proportionality and I'm not sure what goes on the axis. Is the y-axis f and x-axis 1/length^0.5 or is the y-axis 1/f^2 and x-axis le...

**Algebra**

Which point is a solution of the system? Y=x-9 X+2y=3

**math**

where does the "3" go then? 3x^2+3 = 3 x(x^2 + 1) = "3"(x+i)(x-i) because the answer is: (x-1)(3x-1)(x+i)(x-i)

**math**

how do you factor the polynomial 3x^4-4x^3+4x^2-4x+1? i got (x-1)(3x-1)(3x^2+3) but the answer is (x-1)(3x-1)(x+i)(x-i)
