The balanced equation for the redox reaction, which takes place in a basic solution is:
- 2 Cr(OH)₃ + ClO₃⁻ (aq) + 4 OH⁻ → 2 CrO₄²⁻ (aq) + Cl⁻ (aq) + 5 H₂O; <u>option C</u>
<h3>What is the balanced equation for the redox reaction?</h3>
A balanced equation for a redox reaction is one in which the electrons transferred are balanced and the atoms involved in the reaction are also balanced.
To balance redox reactions in a basic solution, OH⁻ ions and H₂O are placed on appropriate sides of the reaction.
Considering the given reaction:
Cr(OH)₃ + ClO₃⁻ (aq) → CrO₄²⁻ (aq) + Cl⁻ (aq):
The balanced equation will be:
2 Cr(OH)₃ + ClO₃⁻ (aq) + 4 OH⁻ → 2 CrO₄²⁻ (aq) + Cl⁻ (aq) + 5 H₂O
The electrons transferred and the atoms involved are balanced.

The mass of acetone to be weighed is
Assuming ideality:
PV=nRT
Pv= (mass/molarmass)RT
Solve for the mass :-)
Answer: Calcium
Explanation: The chemical element Calcium (Ca), atomic number 20, is the fifth element and the third most abundant <u><em>metal</em></u> in the earth's crust. The metal is trimorphic, harder than sodium, but softer than aluminium.
