How does the radius size change when a metal atom becomes an ion? A. The radius size increases: + ion is larger than neutral atom

B. The radius size decreases: - ion is smaller than the neutral atom

C. The radius size decreases: + ion is smaller than neutral atom

D. The radius size increases: - ion is larger than neutral atom

The answer is 27.7

According to this equation:
q = M C ΔT
When q= the energy that produced when there is a difference in temperature.
M (g) = amount of the material= 1.900 Kg= 1900 g
ΔT= difference in temperature ( in kelvin or C°)= 4.542 K
C= Specific heat capacity=3.21

∴ q = 1900 * 4.542 * 3.21 = 27701.7 J = 27.7 KJ
