In the three-dimensional structure of methane, ch4, the hydrogen atoms attached to a carbon atom are aligned at

Corner of tetrahedral structure

Explanation:

In three dimension methane has tetrahedral structure in which central atom is carbon which has four valance electron.

Each valence electron of carbon is shared by hydrogen atom as there are 4 valence electron in so there will be 4 hydrogen atom

And each hydrogen atom is aligned at the corner of tetrahedral structure of

h let me think

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.
