Answer:
4
Explanation:
bromothymol blue turns yellow betwwen then pH levels of 2 and 6
Answer:
final concentration: Ca = 0.014 M
Explanation:
Velocity of reaction:
∴ α: order of reaction, assuming α = 1
∴ K = 0.249 s-1.......rate constant
∴ Cao = 0.050 M......initial concentration
∴ t = 5 s.......reaction time
⇒ δCa/δt = K*Ca
⇒ ∫δCa/Ca = K*∫δt
⇒ Ln(Cao/Ca) = K*t = (0.249s-1)(5 s) = 1.245
⇒ Cao/Ca = 3.473
⇒ Ca = 0.050/3.473
⇒ Ca = 0.014 M
28.0 x 0.6424 = 18
25.0 x .6424 = 16.1
Mass = 34.1
<span>When sodium reacts with ethanol, hydrogen gas liberates and leaves a colorless solution of Alkoxide
Reaction: 2CH</span>₃CH₂OH + 2Na → 2CH₃CH₂ONa + H₂
So, in short the answer of your particular question will be "Hydrogen Gas"
Hope this helps!!!
