Answer:
C. ionic
Explanation:
Na has 11 electron and Na has 1 electron outer shell
Cl has 17 electron and Cl has 7 electron outer shell
By giving 1 electron to Cl, Na become stable and by getting 1 electron the outer shell of fills it octate.
Carbonic acid. Because roots are not photosynthetic, they produce carbon dioxide like you do. Carbon dioxide combines with water to form the mild acid carbonic acid.
Answer:
869.93J/g°C
Explanation:
From the question given, we obtained the following:
M = 42.6g
T1 = 12°C
T2 = 46°C
ΔT = T2 — T1 = 46 — 12 = 34°C
C =?
Q = 1260 KJ = 1260000J
Q = MCΔT
C = Q / MΔT
C = 1260000 /(42.6 x 34)
C = 869.93J/g°C
Therefore, the specific heat capacity is 869.93J/g°C
