<h2>
Answer: Mg²⁺ & N³⁻</h2>
<h3>
Explanation:</h3>
Magnesium (group IIA) loses two electrons to become a cation. This is the most energetically favorable way for Magnesium to obtain a valence electron that is stable (octet). When an atom loses electrons it has a positive charge that matches the number of electrons lost.
Nitrogen (group VA) gains three electrons to become an anion. This is the most energetically favorable way for Nitrogen to obtain a valence electron that is stable (octet). When an atom gains electrons it has a negative charge that matches the number of electrons gained.

Answer:
Percent yield = 94.5%
Theoretical yield = 26.89 g
Explanation:
Given data:
Mass of copper = 12.5 g
Mass of copper chloride produced = 25.4 g
Theoretical yield = ?
Percent yield = ?
Solution:
Cu + Cl₂ → CuCl₂
Number of moles of Copper:
Number of moles = mass/ molar mass
Number of moles = 12.5 g/ 63.55 g/mol
Number of moles = 0.2 mol
Now we will compare the moles of copper with copper chloride.
Cu : CuCl₂
1 : 1
0.2 : 0.2
Theoretical yield:
Mass of copper chloride:
Mass = Number of moles × molar mass
Mass = 0.2 mol × 134.45 g/mol
Mass = 26.89 g
Percent yield:
Percent yield = Actual yield / theoretical yield × 100
Percent yield = 25.4 g/26.89 g × 100
Percent yield = 94.5%
Answer:
Transverse waves are known by motion being perpendicular to the waves movements. Longitudinal waves move in a direction parallel to the way the wave moves. Water waves are an example of both as they move in a clockwise motion.
