Molar mass H₃PO₄ = 98.0 g/mol
1 mole ----- 98.0 g
? mole ------ 30.0 g
moles = 30.0 * 1 / 98.0
= 0.306 moles
hope this helps!
These atoms are bonding to increase their stability and decrease their energy levels by bonding into electron configurations that follow the Octet Rule. The Octet Rule relates to atoms wanting to have 8 valence electrons in their outer-most electron shell. Noble gases are the only elements to already have 8 valence electrons before bonding. For this reason, Noble gases are usually already stable low energy atoms that are less likely to form bonds than all the other elements on the periodic table.
Answer: This is called fulfilling the Octet Rule.

Answer:
When the speed of an object remains the same for a certain distance of time
Explanation:
1. Yes because the ocean takes in the carbon dioxide from the air. This causes more acid in the water, this makes it hard to make shells and skeletons for the seal life that need them.
2.No because it isn't harmful unless it builds up. But there is people who work to clean and limit the chances of build-up.
