Answer:
2. Ne
Explanation:
Neon is an element. You cannot break down an element by chemical means.
1, 3, and 4 are wrong. They are all compounds, and compounds can be broken down by chemical means.
Given:
Q = 45.5 J, amount of heat absorbed
ΔT = 28.5 - 21.1 = 7.4 °C = 7.4 K, temperature change
c = 0.82 J/(g-°C), specific heat of CaCO₃.
Le m = the mass of the sample (g).
Then
Q = mcΔT
(45.5 J) = (m g)*(0.82 J/(g-°C))*(7.4 °C)
m = 45.5/(0.82*7.4) = 7.4984 g
Answer: 7.5 g (nearest tenth)
