Answer:
You make aluminum phosphate which is an insoluble salt, so a precipitated is formed.
Explanation:
First reagent: Al(NO₃)₃
Second reagent: (NH₄)₃PO₄
This is the reaction:
Al(NO₃)₃ (aq) + (NH₄)₃PO₄ (aq) → AlPO₄ (s) ↓ + NH₄NO₃ (aq)
Al³⁺ (aq) + PO₄⁻³ (aq) ⇄ AlPO₄ (s) ↓ Kps
Salt from phosphate is formed.
Answer: because it is
Explanation: to be honest is just is there is not explanation needed
Answer:
a. Rate = k×[A]
b. k = 0.213s⁻¹
Explanation:
a. When you are studying the kinetics of a reaction such as:
A + B → Products.
General rate law must be like:
Rate = k×[A]ᵃ[B]ᵇ
You must make experiments change initial concentrations of A and B trying to find k, a and b parameters.
If you see experiments 1 and 3, concentration of A is doubled and the Rate of the reaction is doubled to. That means a = 1
Rate = k×[A]¹[B]ᵇ
In experiment 1 and to the concentration of B change from 1.50M to 2.50M but rate maintains the same. That is only possible if b = 0. (The kinetics of the reaction is indepent to [B]
Rate = k×[A][B]⁰
<h3>Rate = k×[A]</h3>
b. Replacing with values of experiment 1 (You can do the same with experiment 3 obtaining the same) k is:
Rate = k×[A]
0.320M/s = k×[1.50M]
<h3>k = 0.213s⁻¹</h3>
i dont know how to remove my answer so ignore this
