Calculate E_cell' for the reaction 2 Ag^+(aq) + Pb(s) + SO_4^2- (aq) rightarrow 2 Ag(s) + PbSO_4(s) +40.44 V -0.44 V +1.16 V + 1.95 V -1.16V Which of the following reactions is an example of electron capture?^58_26Fe +^1_0n rightarrow^59_26Fe^7_3Li +^1_1P rightarrow 2^4_2He^227_89Ac rightarrow^223_57Fr +^4_2He^135_57La +^0_-1e rightarrow^135_56Ba What role do the cadmium control rods play in a fission reactor? The cadmium acts as a catalyst, enabling fission to occur at lower temperatures. The rods control the rate of fission by absorbing neutrons. The rods focus the neutrons toward the center of the reactor. The cadmium combine with spent uranium fuel to produce a non-radioactive product. The rods move forward and backward, driving the pistons that turn the turbines. What is the correct cell notation for a voltaic cell based on the reaction Ag^+(aq) + Sn(s) rightarrow Ag(s) Sn^2+ Sn(s) || Sn^2+(aq), Ag^+(aq) | Ag(s) Ag(s) || Ag^+(aq), Sn^2+(aq) || Sn(s) Sn(s) | Sn^2+(aq) || Ag^+(aq) | Ag(s) Ag(s) | Ag^+(aq) || Sn^2+(aq) | Sn(s) Ag(s) | Sn^2+(aq) || Ag^+(aq) | Sn(s) The molar mass of a boron-10 nucleus is 10.012937 g/mol. Nucleon masses: proton = 1.007825 amu. 1.008665 amu. Calculate the binding energy (in J/mol) of^10B. 9.000 times 10^13 J/mol 2.084 times 10^2 J/mol 6.248 times 10^15 J/mol 6.248 times 10^12 J/mol 9.000 times 10^14 J/mol What particle(s) are produced in the following reaction? 4^0_+1beta^4_2He 2^0_-1beta 4^1_0n^1_-1P It a nucleus decays by successive alpha, beta, alpha panicle emissions. its atomic number will decrease by. 3 2 5 4 8Explanation / Answer
22) just add the reduction potentials of each ion to get Ecell
23) Electron capture is a process where unstable atoms can become more stable. During electron capture, an electron in an atom's inner shell is drawn into the nucleus where it combines with a proton, forming
a neutron and a neutrino.
Option E is the answer , because it is the only one which captures electron.
24) Option B is the anwer , they are designed to absorb neutrons , without fissioning themselves ,to control
the fission rate
25) Electrode (s) | aqueous (oxidation) || aqueous (reduction) | electode (s)
Sn is undergoing oxidation and Ag+ is undergoing reduction
So, option C is the answer.
26) 10B has 5 protons and 5 neutrons
total mass will be = 5(1.007825 amu) + 5(1.008665 amu) = 10.08245 amu
total mass - nuclear mass = 0.069513 amu
6.951300 x 10-5 kg of mass is equivalent to the binding energy of one mole of 10B nuclei
E = mC2 = (6.951300 x 10-5 ) * (2.998* 108)2 = 6.2478*1012 J/mol
Option D is the answer.
27) option D
28) It decreases by two for the first alpha emission, for next beta emission, it increases by 1 and for the last alpha
emission it again decreases by 2
So, it will decrease by 3, Option A is the answer
