Final answer:
NH3 is formed through covalent bonding of nitrogen and hydrogen. N2 is formed through a triple covalent bond between nitrogen atoms. CH4 is formed through covalent bonding of carbon and hydrogen. CO2 is formed through covalent bonding of carbon and oxygen.
Step-by-step explanation:
A) NH3: Nitrogen and hydrogen react to form ammonia (NH3) through covalent bonding. Ammonia is a molecule with one nitrogen atom bonded to three hydrogen atoms. The nitrogen atom has five electrons in its outermost energy level, and it forms three covalent bonds with hydrogen atoms. The Lewis structure of ammonia is shown as H - N - H - H. The name of the product is ammonia.
B) N2: Nitrogen atoms bond together to form a diatomic molecule (N2) through a triple covalent bond. Each nitrogen atom has five electrons in its outermost energy level, and they share three pairs of electrons to form the triple bond. The Lewis structure of nitrogen gas is shown as N = N. The name of the product is nitrogen gas.
C) CH4: Carbon and hydrogen atoms bond to form a molecule of methane (CH4) through covalent bonding. Methane is a molecule with one carbon atom bonded to four hydrogen atoms. The carbon atom has four electrons in its outermost energy level, and it forms four covalent bonds with hydrogen atoms. The Lewis structure of methane is shown as H - C - H - H - H. The name of the product is methane.
D) CO2: Carbon and oxygen atoms bond to form a molecule of carbon dioxide (CO2) through covalent bonding. Carbon dioxide is a molecule with one carbon atom bonded to two oxygen atoms. The carbon atom has four electrons in its outermost energy level, and it forms two covalent bonds with oxygen atoms. The Lewis structure of carbon dioxide is shown as O = C = O. The name of the product is carbon dioxide.
