A reaction vessel is filled with 4.04 g of hydrogen gas and 16.0 g of oxygen gas, and the mixture explodes. Identify the limiting reactant and deduce the mass of water produced. Be sure to explain how you determined your answers. Unbalanced reaction: H subscript 2 plus O subscript 2 rightwards arrow H subscript 2 O

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of c is as shown here in the image.

"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."
