Answer:
3566.4 days
Explanation:
The reaction follows a first-order
Rate = kC = change in concentration/time
k = 0.2 day^-1
C = 0.14 mg.L^-1
Co = 100 mg.L^-1
0.2×0.14 = 100 - 0.14/t
t = 99.86/0.028 = 3566.4 days
False it is actually called a neutralization reaction.
BCl₃ is Lewis acid, that is an acceptor of electronic couple. Borum accepts electronic couple on the emptiest orbital.
BCl₃ + HCl = H[BCl₄]
BCl₃ + Cl⁻ = [BCl₄]⁻
Lewis base
acid
Aluminum and copper because all of them have advantages and disadvantages over iron alloys.
