Answer: it holds two atoms together in a molecule. During a chemi- cal reaction, some of the bonds in the original molecule break. New bonds form to produce a new substance.
Explanation:
For this item, we find first the mass of the compound with the empirical formula. That is,
molar mass = 12 (for C) + 1 (for H)
= 13 g/mole
Then, we divide the given mass of the molecular formula by the mass of the empirical formula.
n = 52.07 / 13 = 4
Therefore, the molecular formula is C₄H₄.
Dry air is the choice that is vibrating the fastest because its in a gas form which causes particles to vibrate quickly because of the heat.
the correct answer would be C. All matter is made up of molecule because gas is one matter and solid is one matter and water and ice/liquid and solid is not hard to see, so the correct answer would be C. All matter is made up of molecule.
