What is the coefficient for oh−(aq) when s2−(aq) no3−(aq) → s(s) no(g) is balanced in basic aqueous solution?
omeli [17]

From the balanced redox equation of the reaction, the coefficient of OH⁻ is 8.

<h3>What is the balanced redox equation of the reaction?</h3>

A redox equation is the equation of a redox reaction in which oxidation and reduction occurs simultaneously.

The given redox reaction takes place in a basic solution

The balanced redox equation of the reaction is given below:

4 H₂O(l) + 3 S²⁻(aq) + 2 NO₃⁻(aq) ---> 3 S(s) + 2 NO + 8 OH⁻(aq)

In conclusion, a redox equation is balanced when oxidation and reduction occur to the same extent.

(b) What amount (mol) of CaO can be produced from the given mass of O₂?
TEA [102]

The amount of Ca is not limiting, we have : 2.87g of O_{2} will produce : 2.87 / 56.1 = 0,051158645 mol of CaO

What is Mass?

Mass is a property that represents the amount of matter in a sample. Mass is often expressed in grams (g) and kilograms (kg) (kg). Mass can alternatively be defined as the property of matter that provides it the ability to resist acceleration. The more mass an object has, the more difficult it is to accelerate.
