Answer:
c
Explanation:
we cannot say that either will die out, because we dont know the conditions. but we know that both sides out the mountian arent exactly the same, so we know they will evolve to adapt and grow with what they have
Answer:
All the above
Explanation:
A. Electrical current conduction
Aqueous solutions of both strong and weak acids will conduct an electric current. Weak acids are poorer conductors because they produce fewer ions.
B. Reaction with magnesium
Both strong and weak acids will react with magnesium, although weak acids will react more slowly.
C. pH paper test
Both strong and weak acids will give a colour with pH test paper, although the colours will probably be different.
D. Litmus paper test
Both strong and weak acids will turn blue litmus red.
Answer: 18634 joules
Explanation:
The quantity of Heat Energy (Q) released when a heated substance is cooled depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)
Thus, Q = MCΦ
Since,
Q = ?
Mass of oil = 345g
C = 0.220 J/g°C
Φ = (Final temperature - Initial temperature)
= 0°C - 220°C = -220°C
Then, Q = MCΦ
Q = 345g x 0.220 J/g°C x -220°C
Q = 18634 joules (note that negative sign will not reflect in answer, because it only indicates that heat was released rather than gained)
Thus, 18634 joules of heat is released
