Select the correct answer. Carbon burns in the presence of oxygen to give carbon dioxide. Which chemical equation describes this reaction?

А. carbon + oxygen + carbon dioxide

B. carbon + oxygen carbon dioxide

C. carbon dioxide - carbon + oxygen

D. carbon dioxide + carbon - oxygen

Basically, carbon (C2) burns in the presence of adequate Oxygen (O2) to form carbon dioxide. Carbon is Quadro valent and is able to accept four more electrons. Oxygen has two electrons and hence, readily reacts with carbon to help break and make bonds. The chemical equation of carbon dioxide (CO2) is

carbon + oxygen → carbon dioxide or C2 + O2 = CO2

C

Explanation:

Because it is the question that represents than carbon in the presence of oxygen give carbon dioxide.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
