<span>The answer to this question would be: placement of electrons only
An atom with resonance structure or mesomerism has one or more different structure with different placement of the electron. The atom should have a same amount of electron but only differ in the electron position. This will result in a different Lewis structure model. In this structure, you can find </span>π electrons pair.<span>

Answer:
80g
Explanation:
2H2 + O2 —> 2H2O
MM of H2O = (2x1) + 16 = 2 + 16 = 18g/mol
Mass conc. of H2O from the balanced equation = 2 x 18 = 36g
MM of O2 = 16 x 2 = 32g/mol
From the equation,
32g of O2 reacted to produce 36g of H2O.
Therefore Xg of O2 will react to produce 90g of H2O i.e
Xg of O2 = (32x90)/36 = 80g
In order for a solute to dissolve in a solvent, the attractive forces in a solute need to be broken. So, the best option is A.
It is at the right of it..
Answer:
47.5 g of water can be formed
Explanation:
This is the reaction:
CH₄ + 2O₂ → CO₂ + 2H₂O
Methane combustion.
In this process 1 mol of methane react with 2 moles of oxygen to produce 2 moles of water and 1 mol of carbon dioxide.
As ratio is 1:2, I will produce the double of moles of water, with the moles of methane I have.
1.320 mol .2 = 2.64 moles
Now, we can convert the moles to mass (mol . molar mass)
2.64 mol . 18g/mol = 47.5 g
