Answer:
B
Explanation:
Because the iron is wrong because of the contemplation of bisectors interfere with the question making it B.
Q = mCpΔT —> Solve for Cp —> Cp = q/mΔT
q = -6700 J (negative because it released heat
m = 70 g
ΔT = Final temp - initial temp = 25 - 90 = -65°C
Cp = -6700 J / (70 g)(-65°C) = 1.47 J/g°C
Answer:
A. Elastic
Explanation:
an elastic collision is one which there is no overall loss of kinetic energy
Answer:
ion exchange is the exchange of ions of the same charge between an insoluble solid and a solution in contact with it, used in water-softening and other purification and separation processes.
