They are both strong, corrosive acids. Hydrochloric acid can be synthesize using table salt and sulfuric acid.
The question is incomplete, here is the complete question:
A chemist measures the amount of nitrogen gas produced during an experiment. She finds that of 282. g of nitrogen gas is produced. Calculate the number of moles of nitrogen gas produced. Be sure your answer has the correct number of significant digits.
<u>Answer:</u> The number of moles of nitrogen gas produced are 10.07 moles
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
![\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20moles%7D%3D%5Cfrac%7B%5Ctext%7BGiven%20mass%7D%7D%7B%5Ctext%7BMolar%20mass%7D%7D)
We are given:
Given mass of nitrogen gas = 282 g
Molar mass of nitrogen gas = 28 g/mol
Putting values in above equation, we get:
![\text{Moles of nitrogen gas}=\frac{282g}{28g/mol}=10.07mol](https://tex.z-dn.net/?f=%5Ctext%7BMoles%20of%20nitrogen%20gas%7D%3D%5Cfrac%7B282g%7D%7B28g%2Fmol%7D%3D10.07mol)
Hence, the number of moles of nitrogen gas produced are 10.07 moles
The Calcium ion is an Alkaline earth metal and wants to give up the 2 s orbital elections and become a +2 cation.
Oxygen has six valence electrons and is looking to gain two electrons to complete the octet (8) electron count in the valence shell making it a -2 anion.
When the charges of the Calcium +2 and the Oxygen -2 are equal and opposite, the ions for an electrical attraction. (Remember Paula Abdul told us "Opposites Attract")
This one to one ratio of charges makes the formula CaO
