The rate law for the reaction : r=k.[A]²

<h3>Further explanation</h3>

Given

Reaction

A ⟶ B + C

Required

The rate law

Solution

The rate law is a chemical equation that shows the relationship between reaction rate and the concentration / pressure of the reactants

For the second-order reaction it can be:

1. the square of the concentration of one reactant.

\tt r=k[A]^2

2. the product of the concentrations of two reactants.

\tt r=k[A][B]

And the reaction should be(for second order) :

2A ⟶ B + C

Thus, for reaction above (reactant consumption rate) :

\tt r=-\dfrac{\Delta A}{2\Delta t}=k[A]^2

Are alchemy and chemistry the same
Anit [1.1K]

Are alchemy and chemistry the same: No

<u>Explanation:</u>

Alchemy and chemistry differ from each other. Their main difference lies in the concepts that they are based on. Alchemy has the base of viewing the reality of nature supernaturally. Chemistry has a base of viewing the reality in a natural way.

Protoscience is the name given for Alchemy. This is because that alchemy usually focuses on the traditional things like procedures and  terminologies. Chemistry always focuses on the matter and their transformations. The matter and its transformations are dealt with chemistry.

Where do convection currents form?
pshichka [43]

Answer:

I think it's C

<u>Convection currents are identified in Earth's mantle. Heated mantle material is shown rising from deep inside the mantle, while cooler mantle material sinks, creating a convection current. It is thought that this type of current is responsible for the movements of the plates of Earth's crust.</u>

Determine the hydroxide ion concentration in a solution that is 0.018 m naoh.
nydimaria [60]
As we know, NaOH is a strong Base and completely dissociates in water as given below,

                            NaOH + H₂O    →   Na⁺ ₍aq₎  +  OH⁻ ₍aq₎

So, the concentration of OH⁻ Ions will be the same as that the concentration of NaOH i.e. 0.018 M.
So,
                                     [OH⁻]  =  0.018 M
