Answer:
Y³⁻ A non metal that gained three electrons.
V²⁺ A metal that lost two electron
Z²⁻ A non metal that gained two electrons
X³⁺ A metal that lost three electrons
Explanation:
Metals lost the electrons and form cation
while non metals gain the electrons and form anion.

A radio changes electricity into sound energy.
Answer:
26.5°C
Explanation:
Heat added is the product of mass, specific heat capacity, and change in temperature.
q = mC(T − T₀)
25.7 cal = (18.4 g) (0.215 cal/g/°C) (T − 20.0°C)
T = 26.5°C
