Answer: well the the nuclear charge of nitrogen is 7
but the Oxygen is in the 6A group which means that oxygen has 6 valence electrons.
Explanation:
Answer: A) 0.20 L
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
According to the neutralization law,
where,
= molarity of stock 
solution = 10.0 M
= volume of stock solution = ?
= molarity of dilute solution = 0.50 M
= volume of dilute solution = 4.0 L
Therefore, the volume of 10.0 M solution needed to prepare 4.0 L of 0.50 M is 0.20 L
<em>ANSWER:</em>
Objects that have the same charge, both positive or both negative, repel each other, and those with opposite charges attract each other. ... Similar to electric charges, opposite poles attract, and like poles repel. The stronger the magnets and the closer together they are, the stronger the magnetic force between them.
