Chromium metal is added to a solution of nickel(ii) sulfate. what is the balanced chemical reaction?

Answer : The balanced chemical reaction is,

Explanation :

The balanced chemical reaction is,

This is a single step displacement reaction. From the reactivity series of the metals, the reactivity of the chromium metal is higher than the reactivity of the nickel metal. Therefore, the chromium metal easily displaces the nickel metal from the solution of nickel(II) sulfate. The reactivity series image attached below.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
