When the oxide of generic metal M is heated at 25.0 °C, only a negligible amount of M is produced. MO2(s)<-->M(s)+O2(g) DeltaS= 287.5 kJ/mol When this reaction is coupled to the conversion of graphite to carbon dioxide, it becomes spontaneous. What is the...

derivative of h(x)= 3(√x) - x(√x)

The strength, S, of a rectangular wooden beam is proportional to its width times the square of its depth. Find the dimensions of the strongest beam that can be cut from a 12 inch diameter cylindrical log.

You are designing a 1000 cubic cm closed cylindrical can with radius r and height h. Assume that there is no waste in cutting the aluminum for the side of the can, but that the circular top and bottom are cut from square sheets of aluminum 2r by 2r. Find...

During the discharge of an alkaline battery, 4.50 g of Zn is consumed at the anode of the battery. a) What mass of MnO2 is reduced at the cathode during this discharge? b) How many Coulombs of electrical charge are transferred from Zn to MnO2?

Elemental calcium is produced by the electrolysis of molten CaCl2. a) What mass of calcium can be produced by this process if a current of 7.5 * 10^3 A is applied for 48h? Assume that the electrolytic cell is 68% efficient. b) What is he minimum voltage n...

Balance the following equation in basic solution. Phases are optional. I{-}+IO4{-} --> I3{-}+IO3{-}

An open top box with a square base is to be made so that it holds 3 cubic feet. Assuming the material on the base costs $3 per square foot and the material on the sides costs $2 per square foot, determine the size of the base that minimizes the total cost...

What is the activity of a 18.9 μCi sample of carbon-14 in becquerels?

a) 45.02% of the sample remains after 85 days. Consider how you can use the percent of Ir-192 remaining and the number of days to calculate the mass remaining after 85 days.

Use u-substitute to compute the following: A) ∫((x)/((x^2)+5)) dx B) ∫((sin(ln(x)))/(x)) dx

It's the first time I ask this question on here actually.

I looked at one of your description of one of the previous questions asked that are similar to mine and it made perfect sense. Thanks!

Do you mean : 3/(2√x) - (3/2) √x. ?

Is it required for me to use the chain rule on x(√x)?

Do you mean 2√3 x 2√6?

Cu^2+ --> Cu^+ To balance that out you don't need to add 2e^-

In which case the only one you would need to multiply to get en equal amount of e^- would have to be the half reaction of Cu^2+

Also, I will add that this is a basic solution. A basic solution cannot have an excess of H+. That would make it acidic so you have to add OH^- to both sides of the final equation.

Close. You see how you have 4H^+? To get rid of that you need to add 4OH^-. That will make it into 4H2O. But you have to add 4OH^- to both sides of the equation. Then the H2O will cancel out leaving the OH^- on the left and 2H2O on the right.

You're welcome.

I should have mentioned that the initial mass is 1.75g
