1 answer:
Answer:
3.
Explanation:
- Al(OH)₃ reacts with HCl to produce AlCl₃ and water according to the balanced equation:
<em>Al(OH)₃ + 3 HCl → AlCl₃ + 3H₂O,</em>
<em></em>
<em>It is clear that 1.0 mole of Al(OH)₃ reacts with 3.0 mole of HCl to produce 1.0 mole of AlCl₃ and 3.0 moles of H₂O,</em>
<em />
<em>So, the coefficient of HCl is 3.</em>

Answer:
The answer is 0.01365.
Explanation:
C(t) = 0.0225te^?0.0467t
We can derivate,
C'(t) = d/dt ( 0.0225 te^-0.0467t)
after solving,
C'(t) = 0.0225 (e^-0.0467t - (0.0467e^-0.0467t . t)
Plug in t =5,
Answer is C'(t) = 0.01365.
