Explanation:
A Lewis structure is also called a dot electron structure. A Lewis structure represents all the valence electrons on atoms in a molecule as dots. Lewis structures can be used to represent molecules in which the central atom obeys the octet rule as well as molecules whose central atom does not obey the octet rule.
Sometimes, one Lewis structure does not suffice in explaining the observed properties of a given chemical specie. In this case, we evoke the idea that the actual structure of the chemical specie lies somewhere between a limited number of bonding extremes called resonance or canonical structures.
The canonical structure of the carbonate ion as well as the lewis structure of phosphine is shown in the image attached to this answer.
Answer:You can view more details on each measurement unit: molecular weight of BaCl2 or grams This compound is also known as Barium Chloride. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles BaCl2, or 208.233 grams.

Answer:
mass of oxygen = 80.077 grams
Explanation:
From the periodic table, we can find that:
atomic mass of oxygen = 16 grams
atomic mass of phosphorus = 30.97 grams
The balanced equation is:
4P + 5O₂ ..............> 2P₂O₅
From this balanced equation we can note that:
4 moles of P are required to react with 5 moles of O₂
This means that:
4 * 30.97 = 123.88 grams
are required to react with
5 * (16*2) = 160 grams
Therefore, to know the mass of oxygen required to react with 62 grams of phosphorus, all we have to do is cross multiplication as follows:
123.88 grams of phosphorus ..................> 160 grams of oxygen
62 grams of phosphorus .........................> ?? grams of oxygen
mass of oxygen = (62*160) / (123.88) = 80.077 grams
Hope this helps :)
