Calculate ℰ° values for the following cells. Which reactions are spontaneous as written (under standard conditions)? Balance the reactions. Standard reduction potentials are found in the table . (Use the lowest possible coefficients. Omit states-of-matter in your answer.) Answers should have the appropriate number of significant figures. (a) MnO4− (aq) + I − (aq) I2(aq) + Mn2+(aq) E°cell V (b) MnO4− (aq) + Cl − (aq) Cl2(g) + Mn2+(aq) E°cell V

A plant bought a calciner for P220,000 and used it for 10 years, the life span of the equipment. Assume a scrap value of P20,000 for straight line method; P22,000 for textbook declining balance method and P20,000 for the double declining balance method. What is the book value of the calciner after 6 years of use?  (a) Using Straight Line Method (b) Using Declining Balance Method (c) Using Double Declining Balance Method

A 181 ‑turn circular coil of radius 2.03 cm and negligible resistance is immersed in a uniform magnetic field that is perpendicular to the plane of the coil. The coil is connected to a 16.5 Ω resistor to create a closed circuit. During a time interval of 0.135 s, the magnetic field strength decreases uniformly from 0.627 T to zero. Find the energy 𝐸 in millijoules that is dissipated in the resistor during this time interval.

The following equations describe the variation of pressure p with veloci 0 p + A og V-2 = X (i) p + B g pv = Y (iii) p + CPV 2 = Z where, A, B, and C are dimensionless constants. X, Y, and Z are values with the same dimensions as pressure, g is the acceleration due to gravity, p is the density of the liquid, and o is the surface tension of the liquid. Which equations are dimensionally homogeneous? 2:33 PM
