If you are having trouble with Chemistry, Organic, Physics, Calculus, or Statistics, we got your back! Our videos will help you understand concepts, solve your homework, and do great on your exams.Solved: Write balanced chemical equations for: Chromium metal is immersed in an aqueous solution of cobalt(II) chloride. By signing up, you'll get…Dichromate(VI) ions (for example, in potassium dichromate(VI) solution) can be reduced to chromium(III) ions and then to chromium(II) ions using zinc and either dilute sulphuric acid or hydrochloric acid. Hydrogen is produced from a side reaction between the zinc and acid. This must be allowed to escape, but you need to keep air out of the

Write balanced chemical equations for: Chromium metal is – Figure 1. When a clean piece of copper metal is placed into a clear solution of silver nitrate (a), an oxidation-reduction reaction occurs that results in the exchange of Cu 2+ for Ag + ions in solution. As the reaction proceeds (b), the solution turns blue (c) because of the copper ions present, and silver metal is deposited on the copper strip as the silver ions are removed from solution.Which metal below would make an appropriate metallic container in which to store an aqueous cobalt(II) chloride solution? A. iron B. aluminum C. zinc D. tin E. none of these metalsChromium metal is immersed in an aqueous solution of cobalt (II) chloride (Include all phases)

CHROMIUM – chemguide – Cobalt(II) chloride is often used in humidity indicators because in dry form it is blue and when hydrated it is pink. The radioactive isotope of cobalt, Co-60, is used in portable "x-ray" devices. It actually produces gamma rays which can be used to detect internal flaws in metal in much the same way as x-rays by producing a shadowy image on film.a precipitate is expected when an aqueous solution of potassium iodide is added to an aqueous solution of: sodium sulfate iron(II) chloride calcium perchlorate barium hydroxide lead nitrate . general chem. Using the activity series (Table 4.5), write balanced chemical equations for the following reactions.A galvanic cell with a measured standard cell potential of 0.27 V is constructed using two beakers connected by a salt bridge. One beaker contains a strip of gallium metal immersed in a 1 M solution of GaCl 3, and the other contains a piece of nickel immersed in a 1 M solution of NiCl 2. The half-reactions that occur when the compartments are
