Reaction involved in present electrochemical cell,
At Anode: Zn → Zn^2+ + 2e^2-
At cathode: Zn^2+ + 2e^2- → Zn
Net Reaction: Zn + Zn^2+ ('x' m) → Zn^2+(0.1 m) + Zn
Number of electrons involved in present electrochemical cell = n = 2
According to Nernst equation for electrochemical cell,
Ecell = -2.303
= 0.014
Given: T =
, F = 96500 C, R = gas constant = 8.314J/K.mol, [Zn^2+]R = 0.1 m , Ecell = 0.014 v
∴ 0.014 = - 2.303
∴ log
=
= -2.1117
∴ log x = log(0.1) + 2.1117
∴x = 13.09 m
Answer:
Q = 555200 J
Explanation:
∴ mass (m) = 80 kg
∴ c = 3470 J/Kg.K
∴ T1 = 37°C ≅ 310 K
∴ T2 = 39°C ≅ 312 K
⇒ ΔT = T2 - T1 = 312 K - 310 K = 2 K
⇒ Q = (80 Kg)*(3470 J/Kg.K)*(2 K)
⇒ Q = 555200 J ≅ 600000 J ≅ 6 E5 J
Answer:
B. A plant gets the things it needs to survive from its environment.
Neo-pentane represents the Compound A while compound B is n-pentane.
After careful consideration we can say that compounds A and B are alkanes and also isomers of pentane. In chemistry, Isomers are defined as compounds having same empirical molecular formula but different structural formulas due to varying arrangement of atoms.
Now, as per the question statement, compound A gives a single monochlorination product upon heating with the molecule of chlorine i.e. Cl2 showing that the molecule is extremely symmetric. This molecule must be neo-pentane. Refer to image 1.
Similarly, Compound B forms 3 constitutional isomers after undergoing monochlorination. This compound must be n-pentane since three are 3 different types of carbon atoms in the structure. Refer to image 2.
