Answer:
Formaldehyde(CHO) or methanal is your answer.
Answer: Nitrogen
Explanation: materials with high amounts of carbon are considered brown materials so materials with high amounts of nitrogen are considered green
The answer is the option (3) The geometric shape of a CH4 molecule
distributes the charges geometrically. the CH4 is a tetrahedral with the
Carbon atom in the center and the four H atoms in the vertices of the
tetrahedral. The C-H bond angles are all identical which makes the
molecule perfectly symmetrical and so any dipolar moment will cancel
making the molecule non polar.
