Use the standard half-cell potentials listed below to calculate the standard cell potential for the following reaction occurring in an electrochemical cell at 25°c. (the equation is balanced.) 3 cl2(g) + 2 fe(s) → 6 cl⁻(aq) + 2 fe3+(aq) cl2(g) + 2 e⁻ → 2 cl⁻(aq) e° = +1.36 v fe3+(aq) + 3 e⁻ → fe(s) e° = -0.04 v

Astudent carefully transfers 30 g of water and 30 g of alcohol in a glass tube, forming two layers and filling the tube completely. after sealing the tube, the student mixes the solutions, and notices a bubble that forms in the tube. what is the mass of the contents in the glass tube after mixing?

The mass of a neutron is equal to the mass of a proton plus the mass of an electron. true or false false true
