<span>When the gases dihydrogen sulfide and oxygen react, they form the gases sulfur dioxide and water vapor. so the balanced equation is
</span>2H2S(g) + 3O2(g) → 2SO2(g) + 2H2O(l)
hope it helps
The answer is D. 62 Steering Wheels
hope this helps !
KOH added : 7.5 ml
<h3>Further explanation</h3>
Buffer solution of weak acid HCOOH and strong base KOH
Reaction
initial = 100 ml 0.1 M HCOOH = 10 ml mol HCOOH, and x mlmol of KOH
KOH + HCOOH ⇒ COOHK + H₂O
x 10
x x x x
- 10-x x x
[HCOO - ] = 3[HCOOH]
The concept of Standard electrode potential can be used to accomplish this.
<h3><u>
Standard Reduction Potential</u></h3>
The standard reduction potential belongs to the group of potentials known as standard electrodes or standard cells. The difference in voltage between the cathode and anode is known as the standard cell potential. . All of the standard potentials are determined using 1 M solutions, 1 atm, and 298 K.
The probability of reducing a species is known as its standard reduction potential. It is expressed as a reduction half reaction in writing. Below is an illustration where "A" stands for a generic element and "C" represents the charge.
<u>Standard Reduction Potential:</u>
A⁽⁺+Ce⁻→A
For example, copper's Standard Reduction Potential of Eo=+0.340V) is for this reaction:
Cu²⁺+2e⁻→ Cu
The standard reduction potential and the standard oxidation potential are quite similar. It is the propensity of a species to undergo oxidation under normal circumstances. Additionally, it is written as a half reaction.
