The coefficient for Oxygen in the balanced reaction : 3
<h3>Further explanation</h3>
Given
Reaction
C₂H₄ + _ _ O₂ ⇒ _ _ CO₂ + _ _ H₂O
Required
Oxygen coefficient
Solution
C₂H₄ + aO₂ ⇒ bCO₂ + cH₂O
C, left=2, right=b⇒b=2
H, left=4, right=2c⇒2c=4⇒c=2
O, left=2a, right=2b+c⇒2a=2b+c⇒2a=2.2+2⇒2a=6⇒a=3
The equation becomes :
C₂H₄ + 3O₂ ⇒ 2CO₂ + 2H₂O
An example of an exothermic reaction will be formation of ice
Answer:
Answer in explanation
Explanation:
A. Heating the mixture
Before we can explain the effect of a temperature increase, we need to know the type of reaction it is on temperature basis. As heat is produced, this type of reaction is an exothermic reaction. An exothermic reaction is one in which heat is released into the environment. As such, increasing the temperature of an exothermic reaction leads to more reactants being formed. The equilibrium will thus favor the backward reaction
B. Adding an excess of carbon monoxide
This means we are adding more reactants to the mix. This causes an increase in the available reactants necessary for the reaction to take place making it possible for more product to be formed. This thus favors the forward reaction
C. Removing the methanol as it is formed also favors the forward reaction. This favors the forward reaction as there is allocation for more product to be formed
D. Adding a substance that reacts with carbon ii oxide means less reactant availability which makes it possible for the equilibrium to favor the backward reaction as less reactant is available to give more product.
Answer:
D. Oxidation
Explanation:
In an <em>electrolytic cell</em>, oxidation (the loss of electrons) takes place at the anode. At the cathode reduction takes place.
A mnemonic technique that could be used is that the process that starts with a vowel (Oxidation) takes place at the place that also starts with a vowel (Anode).
