The missing mass number, symbol, and atomic number or charge in the given table are to be completed. Concept introduction: In an atom, the sum of the number of protons and neutrons is called the mass number. The number which is written on the upper left corner in the symbol of particle represents the mass number. The atomic number is the number of protons present in an atom. The number which is written on the lower left corner in the symbol of particle represents the atomic number or charge of the particle. The particles are symbolized as: Here, X is the symbol of particle, A is the mass number and Z is the atomic number.

Imagine separating this process into the four stages sketched below. (These sketches show only a portion of the substances, so you can see the density and distribution of atoms and molecules in them.) CH,CN H₂O B 88 C Use these sketches to answer the questions in the table below. The enthalpy of solution AH is negative soln when CH3CN dissolves in water. Use this information to list the stages in order of increasing enthalpy. Would heat be absorbed or released if the system moved from Stage C to D? What force would oppose or favor the system moving from Stage C to D? Check all that apply. 1 absorbed O released neither absorbed nor released. none O ionic bonding force covalent bonding force…

In a system with an anodic overpotential, the variation of ŋ as a function of the current density: 1. at low fields is linear 2. at higher fields, it follows Tafel's law Find the range of current densities for which the overpotential has the same value as when calculated for cases 1 and 2 (maximum relative difference of 5% with respect to the behavior for higher fields). To which overpotential range does this correspond? Data: 10 = 1.5 mA cm², T = 300°C, ẞ = 0.64, R = 8.314 J K 1 mol‍¹ and F = 96485 C mol-1.
