Answer:
to find the number of electrons you need the charge of the element.
Answer:
Explanation:
Using freezing point depression formula,
ΔTemp.f = Kf * b * i
Where,
ΔTemp.f = temp.f(pure solvent) - temp.f(solution)
b = molality
i = van't Hoff factor
Kf = cryoscopic constant
= 1.86°C/m for water
= (0 - (-5.58))/1.86
= 3.00 mol/kg
Assume 1 kg of water(solvent)
= (3.00 x 1)
= 3.00 mol.

<u>Answer:</u> The nuclear equations for the given process is written below.
<u>Explanation:</u>
The chemical equation for the bombardment of neutron to U-238 isotope follows:
![_{92}^{238}\textrm{U}+n\rightarrow _{92}^{239}\textrm{U}](https://tex.z-dn.net/?f=_%7B92%7D%5E%7B238%7D%5Ctextrm%7BU%7D%2Bn%5Crightarrow%20_%7B92%7D%5E%7B239%7D%5Ctextrm%7BU%7D)
Beta decay is defined as the process in which neutrons get converted into an electron and a proton. The released electron is known as the beta particle.
![_Z^A\textrm{X}\rightarrow _{Z+1}^A\textrm{Y}+_{-1}^0\beta](https://tex.z-dn.net/?f=_Z%5EA%5Ctextrm%7BX%7D%5Crightarrow%20_%7BZ%2B1%7D%5EA%5Ctextrm%7BY%7D%2B_%7B-1%7D%5E0%5Cbeta)
The chemical equation for the first beta decay process of
follows:
![_{92}^{239}\textrm{U}\rightarrow _{93}^{239}\textrm{Np}+_{-1}^0\beta](https://tex.z-dn.net/?f=_%7B92%7D%5E%7B239%7D%5Ctextrm%7BU%7D%5Crightarrow%20_%7B93%7D%5E%7B239%7D%5Ctextrm%7BNp%7D%2B_%7B-1%7D%5E0%5Cbeta)
The chemical equation for the second beta decay process of
follows:
![_{93}^{239}\textrm{Np}\rightarrow _{94}^{239}\textrm{Pu}+_{-1}^0\beta](https://tex.z-dn.net/?f=_%7B93%7D%5E%7B239%7D%5Ctextrm%7BNp%7D%5Crightarrow%20_%7B94%7D%5E%7B239%7D%5Ctextrm%7BPu%7D%2B_%7B-1%7D%5E0%5Cbeta)
Hence, the nuclear equations for the given process is written above.
The rate constant of first order reaction at 32. 3 °C is 0.343 /s must be less the 0. 543 at 25°C.
First-order reactions are very commonplace. we have already encountered examples of first-order reactions: the hydrolysis of aspirin and the reaction of t-butyl bromide with water to present t-butanol. every other reaction that famous obvious first-order kinetics is the hydrolysis of the anticancer drug cisplatin.
The value of ok suggests the equilibrium ratio of products to reactants. In an equilibrium combination both reactants and merchandise co-exist. big ok > 1 merchandise are k = 1 neither reactants nor products are desired.
Rate constant K₁ = 0. 543 /s
T₁ = 25°C
Activation energy Eₐ = 75. 9 k j/mol.
T₂ = 32. 3 °C.
K₂ =?
formula;
log K₂/K₁= Eₐ /2.303 R [1/T₁ - 1/T₂]
putting the value in the equation
K₂ = 0.343 /s
Hence, The rate constant of first order reaction at 32. 3 °C is 0.343 /s
The specific rate steady is the proportionality consistent touching on the fee of the reaction to the concentrations of reactants. The fee law and the specific charge consistent for any chemical reaction should be determined experimentally. The cost of the charge steady is temperature established.
