The standard reduction potential for Cu²⁺, the voltage measured between a standard hydrogen electrode and a Cu electrode immersed in a solution where [Cu²⁺] = 1.00 M, is 0.340 V. The positive voltage indicates that the following reaction is spontaneous. H₂(g) + Cu²⁺(aq) → 2H⁺(aq) + Cu(s)
What would be the Cu²⁺ reduction potential if the standard hydrogen electrode was kept the same, but copper electrode were instead immersed in a solution of 0.450 M NaOH that was saturated with Cu(OH)₂? (The Ksp of Cu(OH)₂ is 2.20 × 10⁻²⁰).

Which of the following statements about acidic water is true? a. acid has no effect on the h,o molecules. b. the solution contains a larger number of oh ions than h,o ions. c. the solution contains a larger number of h,o ions than qh ions. d. the solution contains an equal number of h,o ions and oh ions. none of the above e.

What is the mass of 4 molecules of co2

Someone offer some answers to this, i will give 98 coins and mark as brainliest! i will put the rest of the lab down in the comments,solutions pre-lab questions: in this lab, you will make fruit drinks with powdered drink mix. complete the pre-lab questions to get the values you need for your drink solutions. calculate the molar mass of powered fruit drink mix, made from sucrose (c12h22o11).using stoichiometry, determine the mass of powdered drink mix needed to make a 1.0 m solution of 100 ml. (hint: use molarity = to find the moles of drink mix, then convert moles to grams using a mole conversion.)what mass of powdered drink mix is needed to make a 0.5 m solution of 100 ml?
