You are in a position to decide on the purchase of an industrial catalyst for the company you work for, by selecting one of the three offers you have at your disposal. The bidders provided you with the following information for each of the catalysts: active phase mass content, catalytic activity expressed mass of converted raw material relative to the mass unit of catalyst, porosity expressed in units of volume per unit mass of catalyst, selectivity in the desired product expressed as a fraction useful product in total products, shape and size of catalyst granules, bulk density and actual density. a) What are the characteristics based on which you would select the catalyst? Justify your choices. How can I solve this problem?

A piece of zinc was added to 1000cm3 of 0.2M hydrochloric acid. After effervescence had stopped, 28cm3 of the resulting solution required 17cm3 of 0.08M sodium trioxocarbonate IV solution for complete neutralization. Calculate the mass of the zinc added
Using the table of Standard Reduction Potentials
Balance the following equations using the table of half-reaction potentials, determine the E0 and tell whether the reaction will proceed spontaneously or not, and why (don't worry about phase):
1. Fe3+ + Co(s) Co2+ + Fe2+
2. MnO41- + Au(s) Mn2+ + Au3+
3. ClO41- + Mn2+ Cl1- + MnO2
4. IO31- + H2O2 I2 + O2
5. The manganese (II) ion and solid lead react to produce solid manganese and the lead (II) ion.
6. The nitrate ion and the tin (II) ion react to produce nitrogen dioxide and the tin (IV) ion.
