Atomic mass Ca = 40 a.m.u
1 mole Ca ----------- 40 g
2.5 mols Ca -------- ( mass Ca )
Mass Ca = 2.5 x 40 / 1
Mass Ca = 100 / 1
= 100 g of Ca
hope this helps!
Answer:
The energy released is 13.53j
Explanation:
Q = Mc∆temp.
Q = energy
M = mass
c = specific heat capacity
∆temp. = change in temperature
Q = 1 x 0.902 x (35 - 20)
Q = 0.902 x 15 = 13.53j
