Balance the equation below: H2 + O2 ------------ H2O

Chemistry
1 answer:
Andreas93 [3]4 years ago
6 0

<u>Answer</u>:  <em>2</em> H₂  +  O₂    →    <em>2</em> H₂O


<u>Reasoning</u>:

When balancing an equation, what you are trying to do is to ensure that the amount of each atom on the right side (reactant side), is equal to the amount of each atom on the left side (product side), because of the law of conservation of energy.

∴ the balanced equation is    <em> 2</em> H₂  +  O₂    →    <em>2</em> H₂O

Leto [7]

Answer:

3 > 2> 1

Explanation:

Aromatic compounds undergo electrophilic substitution reaction with several electrophiles.

Some substituted benzenes are more reactive towards electrophilic aromatic substitution than unsubstituted benzene.

Certain groups of substituents increase the ease with which an aromatic compound undergoes aromatic substitution.

If we look at the compounds closely, we will notice that only toluene leads to easy reaction with CH3Cl / AlCl3. Thus is due to the +I inductive effect of -CH3 which stabilizes the negatively charged intermediate produced in the reaction.

Explain, in terms of subatomic particles, why the radius of a chloride ion is larger than the radius of a chlorine atom.
den301095 [7]
The radius of a chlorine ion is larger than the radius of a chlorine atom because  the effective nuclear charge decreases, therefore the inward force decreases, increasing the ionic radius.
