From the reaction CaCO3+CO2+H2O= Ca2+ + 2HCO3-   A.) Show how it affects the chemistry of water, alkalinity and hardness of water B.) Its relationship to microbial degradation of organic matter

Thank you I did not connect ln 2 to 0.693 in the first order kinetic equation.

have a rate 13.124. Testing for a Banned Herbicide Sodium chlorate w in EU countries since 2009. A simple colorimetric test for the presence of the chlorate ion in a solution of herbicide was used relies on the following reaction: 2 MnO4 (ag) + 5 C103 (aq) + 6 H*(aq) → 2 Mn2+ (aq) + 5 C104¯(ag) + 3 H,0(0) The table contains rate data for this reaction.

Potentially Useful Information Spectrochemical Series: | < Br < SCN < Cl° < NO3¯< F° < OH° < C2O4²- ~ H2O < NCS < NH3 < en < PPH3 A student synthesizes and isolates the following coordination compound [Ni(H2NCH2CH2NH2)3]Cl2 (molar mass = 309.8966 g/mol) according to the balanced reaction below. In the experiment, the student reacts 2.500 g of nickel (II) chloride hexahydrate (molar mass = 237.6878 g/mol) with 4.000 g of ethylenediamine (molar mass = 60.0992 g/mol). After isolating the product, the student collects 3.200 g of the nickel coordination compound. NICI2•6H2O (aq) + 3H2NCH2CH2NH2 (1) → [Ni(H2NCH2CH2NH2)3]Cl2 (s) + 6H2O (1) Given the transition metal compound, Na4[Co(C204) (CN)4], what is the oxidation state of cobalt, as well as the coordination number of cobalt in this compound? This compound is soluble in water. The oxidation state of cobalt is Cobalt has a coordination number of Your answer should be an integer.
