Answer
not too sure, but perhaps, 24
Explanation:
1 mole = 12 apples
2 moles = 24 apples
The equation is 2Na + Cl₂ ⇒ 2NaCl. <span>Two sodium atoms react with a chlorine molecule (Consisting of two chlorine atoms) that produces two molecules of sodium chloride (common table salt).</span>
Answer:
This is not the correct Lewis structure for formaldehyde.
Explanation:
The chemical equation for formaldehyde is H2CO, therefore if you count all the valence electrons 2+4+6 = 12 (hydrogen has one valence electron, there are two in this compound, carbon has 4, and oxygen has 6). There are 14 valence electrons in the given structure, so that's an indicator its incorrect. Carbon likes to form 4 bonds in order to fulfill the octet rule and oxygen like to form 2 for the same reason. Therefore, carbon and oxygen will form a double bond. Carbon has a single bond with each of the hydrogens, so it does from its favored 4 bonds. Recall we have 12 valence electrons, four valence electrons have been shared between carbon and two hydrogens, four more have been shared between carbon and oxygen, 12-4-4 = 4. There are four valence electron left, carbon achieves the octet rule but oxygen doesn't (it currently "has" four valence electrons), so the four electrons will go to the oxygen to fulfill the octet rule.
Answer:
Hydrogen, Helium, Neon, Argon, Krypton, Xenon, Chlorine, Fluorine, Bromine, Nitrogen, and Oxygen.
