The formulas of chromium(III) fluoride and sodium sulfide are to be written. Concept introduction: Mostly, the elements are found as single atom particles in the universe. For example, the element which exists in the gas phase as single atoms at temperatures is Helium. When atom accepts or loses electrons it is termed as ion. If the ion loses an electron and accepts a positive charge it is called as cation. Similarly, if the ion gains an electron and accepts a negative charge it is called an anion. When the ion is formed from a single atom, it is referred as monatomic ion. But, in nature, many compounds are found as polyatomic ions (poly = many). Polyatomic ions are electronically neutral, for example, ammonium ion will not exist without its counter negative ion. In general, formulas of ionic compounds depict the ratio of positive and negative ions found in a substance. Moreover, the formulas of compounds are made up of lowest whole number ratio of ions i.e., formula unit. Notably, the number of positive units and the number of negative units will be equal in a chemical formula.

Question

A certain half-reaction has a standard reduction potential Ered +1.26 V. An engineer proposes using this half-reaction at the anode of a galvanic cell that must provide at least 1.10 V of electrical power. The cell will operate under standard conditions. Note for advanced students: assume the engineer requires this half-reaction to happen at the anode of the cell. Is there a minimum standard reduction potential that the half-reaction used at the cathode of this cell can have? If so, check the "yes" box and calculate the minimum. Round your answer to 2 decimal places. If there is no lower limit, check the "no" box.. Is there a maximum standard reduction potential that the half-reaction used at the cathode of this cell can have? If so, check the "yes" box and calculate the maximum. Round your answer to 2 decimal places. If there is no upper limit, check the "no" box. yes, there is a minimum. 1 red Πν no minimum Oyes, there is a maximum. 0 E red Dv By using the information in the ALEKS…
