We have the final answer as
<h3>2.7 g/cm³</h3>
Hope this helps you
Answer:
Option A.
Lower air pressure results in a lower boiling point
Explanation:
This is because in an open system, the lower the pressure the lesser the energy that will be required for boiling point. The is little or no collision of air molecules with the surface of the liquid
But if there is increase in pressure, more energy will be required to get to boiling point because there will be strong collision between air molecules and surface of the liquid.
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.
