<span>E = mCdT
E = energy, m = mass, C = specific heat capacity, dT = change in temperature.
526 = 0.074C x 17
E = 0.074C x 55
Divide the equations
E/526 = (0.074C x 55)/(0.074C x 17) = 55/17
E = (55 x 526)/17 = 1702 J</span>
Answer:
A. Position B.
Explanation:
In the summer the northern hemisphere is closer to the Sun so it's Position B.
2 electrons. it has electron configuration of 2.8.8.2 hence the last 2 will be lost for it to gain stable.
