2MnO4-(aq) + 16H+ + 10Cl-(aq) ⇔ 2Mn2+(aq) + 8H2O + 5Cl2 (g)
<h3>Further explanation</h3>
Given
Reaction(unbalanced)
Mno4- (aq) + Cl- (aq) → Mn2+ + Cl2 (g)
Required
Half reaction
Solution
1. Add coefficient(equalizing atoms in reaction)
2. Adding H₂O on the O-deficient side.
3. Adding H⁺ on the H-deficient side.
4. Adding e⁻
5. Equalizing the number of electrons and sum the all the half-reaction
1.MnO₄⁻(aq) = Mn²⁺(aq) reduction
2.MnO4(aq) = Mn2+(aq) + 4H2O
3. MnO4-(aq) + 8H+ = Mn2+(aq) + 4H2O
4. MnO4-(aq) + 8H+ + 5e- = Mn2+(aq) + 4H2O
Cl⁻(aq) = Cl₂(g) oxidation
1. 2Cl-(aq) = Cl2 (g)
2-3 none
4. 2Cl-(aq) = Cl2 (g) + 2e-
5.
MnO4-(aq) + 8H+ + 5e- = Mn2+(aq) + 4H2O x2
2Cl-(aq) = Cl2 (g) + 2e- x5
2MnO4-(aq) + 16H+ + 10e- = 2Mn2+(aq) + 8H2O
10Cl-(aq) = 5Cl2 (g) + 10e-
<em>2MnO4-(aq) + 16H+ + 10Cl-(aq) ⇔ 2Mn2+(aq) + 8H2O + 5Cl2 (g)</em>
Answer:
Option B. 4NH3(g) + 5O2(g) —> 4NO(g) + 6H2O(g)
Explanation:
The reaction between ammonia, NH3 and oxygen, O2, will produce nitric oxide and water as shown below:
NH3(g) + O2(g) —> NO(g) + H2O(g)
Now, let us balance the equation.
This is illustrated below:
NH3(g) + O2(g) —> NO(g) + H2O(g)
There are 3 atoms of H on the left side and 2 atoms on the right side. It can be balance by putting 4 in front of NH3 and 6 in front of H2O as shown below:
4NH3(g) + O2(g) —> NO(g) + 6H2O(g)
There are 4 atoms of N on the left side and 1 atom on the right side. It can be balance by putting 4 in front of NO as shown below:
4NH3(g) + O2(g) —> 4NO(g) + 6H2O(g)
Now, the are 2 atoms of O on the left side and a total of 10 atoms on the right side. It can be balance by putting 5 in front of O2 as shown below:
4NH3(g) + 5O2(g) —> 4NO(g) + 6H2O(g)
Now, we can see that the equation is balanced.
Therefore, option B gives the balanced chemical equation for the reaction.
<span>I am sure these answers are correct cause I've checked all of them. Here they are :
1) The thing which might h</span>appen to the rest of the water is that 61% of that water leaves the ground through evapotranspiration and <span>38% will flow into the Atlantic Ocean.
</span>
2) The four states which receive drinking water from Florida are : <span> South Carolina, Georgia, Alabama, Mississippi
3) The</span> reason why people in Florida wanted to get rid of the water in certain areas is abundance of wetlands. I think there is one more, if it is acceptable I suggest you using this - frequent flooding.<span>
4) </span><span> The negative result of the changes which people made to get rid of the water is the first sign of </span>drought.
5) The thing that has been done to try and improve those mistakes was creating a tool which looked like a dam to prevent dfficulties with <span>navigating the state.
Hope that helps.</span>
Answer:
5. higher
6. shifted down
7. closer together
8. increase its wave length
Explanation:
Answer: Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. ... The fire's heat causes molecules in the pan to vibrate faster, making it hotter. These vibrating molecules collide with their neighboring molecules, making them also vibrate faster.
