Answer:
The more reactive the metal, the more rapid the reaction is. A metal below hydrogen in the reactivity series will not react with dilute acids.
Explanation:
Answer:
Explanation:
The formula for the heat absorbed is
q = mCΔT
Trial 1
m = 30.0 g
ΔT = 40.0 – 0 = 40.0 °C
q₁ = 30.0 × 4.184 × 40.0 = 5020 J
Trial 2
m = 40.0 g
ΔT = 40.0 – 30.0 = 10.0 °C
q₂ = 40.0 × 4.184 × 10.0 = 1670 J
q₁ - q₂ = 5020 – 1670 = 3350 J
The general formula for cycloalkanes is <span>CnH2n .
Now when two cycloalkanes are joined 2 Hydrogens have to be removed.
