How many resonance structures or isomers does ch4 have?
2 answers:
Answer : Methane does not has any resonating structures or isomers.
Explanation : Methane has tetrahedral geometry where all the valence bonds of carbon are satisfied with hydrogen atoms which are similar to each other. They also do not produce any lewis dot structure. Therefore, methane cannot have resonating structures.
Answer:
Zero.
Explanation:
Hello,
As long as methane has hydrogen atoms all around the carbon atom sharing four valance electrons to attain the octate in a tetrahedral structure, no matter where the hydrogens get moved, its molecular arrangement will always have the same Lewis structure or 3D projection (attached picture) in this manner, it does not have any resonance structures.
Best regards.

Answer:
The percent by mass of 3.55 g NaCl dissolved in 88 g water is 3.88%
Explanation:
When a solute dissolves in a solvent, the mass of the resulting solution is a sum of the mass of the solute and the solvent.
A percentage is a way of expressing a quantity as a fraction of 100. In this case, the percentage by mass of a solution is the number of grams of solute per 100 grams of solution and can be represented mathematically as:
In this way it allows to precisely establish the concentration of solutions and express them in terms of percentages.
In this case:
- mass of solute: 3.55 g
- mass of solution: 3.55 g + 88 g= 91.55 g
Replacing:
Percent by mass= 3.88%
<u><em>The percent by mass of 3.55 g NaCl dissolved in 88 g water is 3.88%</em></u>
