Analysis of a volatile liquid shows that it contains 48.64% carbon, 8.164% hydrogen, and 43.20% oxygen by mass. at 150.°c and 1.00 atm, 500. ml of the vapor has a mass of 2.133 g. what is the molecular formula of the compound? (1) c3h6o (2) c3h6o2 (3) c6h12o2 (4) c6h12o4 (5) c9h8o2

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
