Answer:
Genetic modification
Explanation:
a desired trait from one organism is placed into that of another organism with human intervention.
She will use the periodic table of elements to not only find out the chemical symbols of the elements written within the name, but also to check whether or not the elements are metals and or nonmetals, from this determine the ionic charges if needed for metals, and for metals that have more than one ionic charge, use a Roman numeral to represent the ionic charge that she would be using in writing the chemical formula of the compound.
Answer: ![Rate=k[L]^1[M]^2](https://tex.z-dn.net/?f=Rate%3Dk%5BL%5D%5E1%5BM%5D%5E2)
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
![Rate=k[L]^x[M]^y](https://tex.z-dn.net/?f=Rate%3Dk%5BL%5D%5Ex%5BM%5D%5Ey)
(1)
k= rate constant
x = order with respect to L
y = order with respect to M
n =( x+y)= Total order
a) If [L] is doubled, the reaction rate will increase by a factor of 2:
![2\times Rate=k[2L]^x[M]^y](https://tex.z-dn.net/?f=2%5Ctimes%20Rate%3Dk%5B2L%5D%5Ex%5BM%5D%5Ey)
(2)
b) If [M] is doubled, the reaction rate will increase by a factor of 4:
![4\times Rate=k[L]^x[2M]^y](https://tex.z-dn.net/?f=4%5Ctimes%20Rate%3Dk%5BL%5D%5Ex%5B2M%5D%5Ey)
(3)
Dividing 2 by 1:
![\frac{2\times Rate}{Rate}=\frac{k[2L]^x[M]^y}{k[L]^x[M]^y}](https://tex.z-dn.net/?f=%5Cfrac%7B2%5Ctimes%20Rate%7D%7BRate%7D%3D%5Cfrac%7Bk%5B2L%5D%5Ex%5BM%5D%5Ey%7D%7Bk%5BL%5D%5Ex%5BM%5D%5Ey%7D)
Dividing 3 by 1
![\frac{4\times Rate}{Rate}=\frac{k[L]^x[2M]^y}{k[L]^x[M]^y}](https://tex.z-dn.net/?f=%5Cfrac%7B4%5Ctimes%20Rate%7D%7BRate%7D%3D%5Cfrac%7Bk%5BL%5D%5Ex%5B2M%5D%5Ey%7D%7Bk%5BL%5D%5Ex%5BM%5D%5Ey%7D)
Thus rate law is: ![k[L]^1[M]^2](https://tex.z-dn.net/?f=k%5BL%5D%5E1%5BM%5D%5E2)
δg° for the reaction having e° cell = 2.04v. is 393.658kJ.
The lead (Pb) in the lead storage battery act as an anode
<h3>What is Voltaic Cell?</h3>
A voltaic cell or galvanic cell is an electrochemical cell that uses chemical reactions to produce electrical energy.
<h3>Parts of voltaic cell</h3>
Anode where oxidation occurs Cathode where reduction occurs.
Therefore, Pb acts as anode and PbO2 act as a cathode.
Given,
E° cell = 2.04v
Faraday constant= 96485 C/mol
Moles of electron transferred n= 2
∆G = -nFE°
= -2 × 96485 × 2.04
= 393.658kJ
Thus we concluded that the δg° for the reaction having e° cell = 2.04v. is 393.658kJ.
