Explanation:
Group 1A consist of metals and group. 2A consist of non metals . group1A elements can become stable by donating 1 electron in the same way the elements of group 7A also becomes stable by gaining one electron . So due to being so close to being a inert gas element it is compared to the nearest noble gas.
the answer is in the picture, btw the molar mass for the first one is wrong, it should be 77.98, and the final product is 2.32
Answer:
The strength of a bond between two atoms increases as the number of electron pairs in the bond increases.
Explanation:
Molar mass
C₂H₄O₂ = 60.0 g/mol
n = mass / molar mass
3.00 = mass / 60.0
m = 3.00 * 60.0
m = 180 g of <span>C₂H₄O₂
hope this helps!</span>
