Answer:
The types of combustion are;
1) Claudia eating snack is slow combustion
2) Claudia driving home involves explosive combustion
3) The lit candle is a form of rapid combustion
Explanation:
Combustion is the rapid exothermic chemical reaction between a fuel and an oxygen source to produce oxidized compounds formed from the elements in the compounds present in the fuel, which when combined together in a mixture are known as smoke
The types of combustion are;
1) Digestion of the snack is the slow combustion of glucose
2) Combustion in the engine of the car is a form of explosive combustion
3) The burning of the candle is a form of rapid combustion
The mantle is much different from the crust, so I wouldn't think there would be any similarities.
Option a. a type of resistant wire
a revolving structure in an electric motor or generator, wound with the coils that carry the current.
Answer:
MnO₄⁻ + 2 H₂O + 3 e⁻ ⇒ MnO₂ + 4 OH⁻
2 moles of H₂O are on the reactant side.
Explanation:
Let´s consider the following half-reaction.
MnO₄⁻ ⇒ MnO₂
This reduction of permanganate to manganese dioxide happens in a neutral medium. The oxidation number of Mn changes from +7 to +4. When we are in a neutral medium, we can balance the reaction using the ion-electron method either as we were in acid or in basic medium. In this case, to satisfy the condition is the task (<em>water on the reactant side</em>) we will balance this half-reaction as if it were in basic media. Since Mn is already balanced, we have to balance O. We will add as many moles of water as excess of oxygen there is on 1 side, and the double of OH⁻ on the other side. Finally, we add as many electrons as we need to balance it electrically.
MnO₄⁻ + 2 H₂O + 3 e⁻ ⇒ MnO₂ + 4 OH⁻
