What is the value of ΔG°cell? - Socratic ΔG_text (cell)^@= "-332 kJ·mol"^"-1"" Your standard reduction potentials for each half-reaction are: ulbb ("Standard Reduction Potentials"color (white) (mmmmmll)E
What is the chemical formula for lithium hydroxide? - Socratic Lithium is a Group 1 metal and commonly forms a M + ion Hydroxide anion, −OH, has a unit negative charge When they make music together, there is thus 1:1 stoichiometry between ions: Li(s) + H 2O(l) → LiOH (aq) + 1 2 H 2(g) ↑ ⏐ ⏐⏐
What is the formula of magnesium hydroxide? | Socratic Mg (OH)_2 Now we know that hydroxides are salts of HO^-, and some metal ion Now if the parent metal has an electronic configuration of 2:8:2, then there are 12 electrons, and the atomic number of the metal is equal to 12 We look on the Periodic Table, and we find that Z=12, for "magnesium metal" As a Group 2 metal, magnesium forms a Mg^ (2+) ion, and hence its hydroxide is Mg (OH)_2
What makes for a good leaving group? + Example - Socratic A good leaving group has to be able to part with its electrons easily enough, so typically, it must be a strong acid or weak base relative to other substituents on the same molecule It helps to know the pKa of what would be leaving Let's say you had a mechanism where you are trying to do an E2 reaction to make an -OH (hydroxyl) group leave Maybe you have this compound on hand, sec-butanol
What are the factors that make amphoteric oxides able to . . . - Socratic Warning! Long Answer Here's what I find > Basic oxides Metallic character increases from right to left and from top to bottom in the Periodic Table The most metallic elements form the most basic oxides Even if the oxides are insoluble in water, we still call them basic oxides because they react with acids "MgO(s) + 2HCl(aq) → MgCl"_2"(aq)" + "H"_2"O"(l)" Acidic oxides Nonmetallic
How do acid and bases react? + Example - Socratic When an acid and a base are placed together, they react to neutralize the acid and base properties, producing a salt (neutralisation) The H (+) in the acid combines with the OH (-) in the base to form water (colourless) The compound formed by the cation of the base and the anion of the acid is called a salt Example H Cl + N aOH → N aCl + H 2O Hydrochloric acid + Sodium hydroxide →
Calculating the concentration of excess HCL in E - Socratic The acid in excess is then titrated with N aOH (aq) of KNOWN concentration we can thus get back to the concentration or molar quantity of M (OH)2 as it stands the question (and answer) are hypothetical
Question #b6602 - Socratic Here's what I get > a) "CH"_3"CH"_2"CH"_2"-OH" + "SOCl"_2 → "CH"_3"CH"_2"CH"_2"-Cl" + "SO"_2 + "HCl" b) "CH"_3"CH"_2"CH"_2"-OH" + "POCl"_3 + "Py" → "CH"_3"CH=CH
How do you write the chemical equation and - Socratic Kb = [H 4N +][−OH] [N H 3(aq)] = 10−4 75 The concentration of [H O−] in such solutions is low As for the use of ammonia in window cleaner, I suspect the percentage of ammonia in such a product is approx 5 − 10%(w w) With normal use (with gloves), the solution is probably formulated so that it is not too hard on your hands Ammonia solutions are known to give so-called streak free
