Answer:
A. Magnesium
Explanation: Its because Magnesium is Heavier than Bromine and there is 24.3050 atom in Magnesium but there is only two in Bromine

The rate constant : b. 1/ M² · s
<h3>Further explanation </h3>
The reaction rate (v) shows the change in the concentration of the substance (changes in addition to concentrations for reaction products or changes in concentration reduction for reactants) per unit time.
For A + B ---> C + D
Can be formulated:
where
v = reaction speed, M / s
k = constant, mol¹⁻⁽ᵃ⁺ᵇ⁾. L⁽ᵃ⁺ᵇ⁾⁻¹. S⁻¹
a = reaction order to A
b = reaction order to B
[A] = [B] = concentration of substances
Units of the rate constant - k depend on rate law, so it is unique for the specific reaction
So for the rate law :
Δ[C]/ΔT = k[A]²[B] , the units are :
The theoretical molar yield of lead (II) chloride will be 9 moles.
<h3>Stoichiometric calculation</h3>
First, we need to look at the equation of the reaction:
From the equation, the 1 mole of Pb2+ ion requires 2 moles of Cl- ion in order to produce 1 mole of lead (II) chloride.
Thus, with 18 moles Cl- ions, 9 moles of Pb2+ would be needed, instead of 12 moles. Pb2+ is simply in excess while Cl- can be said to be limiting.
Therefore, Cl- will determine how much of lead (II) chloride that will be produced. The ratio is 2 moles of Cl- to 1 mole of lead (II) chloride.
With 18 moles Cl-, 9 moles of lead (II) chloride will, thus, be produced.

#SPJ1
Answer:
The value
Explanation:
From the question we are told that
The thickness of the air is
The temperature is
The total pressure is
The partial pressure of Ammonia first side is
The partial pressure of Ammonia to the second side is
Rate of flow of ammonia is
Generally the molar flux of ammonia is mathematically represented as
Here R is the gas constant with value
=>
It's already balanced since there is an equal number of elements on each side!
