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 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 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
Please can someone help and balance this equation [Ni (H2O)6 . . . - Socratic Well, the first is a chemical equation, the which I am competent to address We make the hexa-ammine nickel(II) complex [Ni(OH_2)_6]^(2+) + 6NH_3(aq) rarr [Ni(NH_3)_6]^(2+) + 6H_2O(l) And the second is a nucular reaction the which DOES NOT conserve mass ""^235U + "neutron" rarr ""^140Xe + ""^94Sr + "2 neutrons " And please compare this with your text, and notes because I am no
Molarity question? - Socratic Consider the precipitation reaction of CuCl2 with NaOH: CuCl2 (aq) + 2NaOH (aq) -> Cu (OH)2 (s) + 2NaCl (aq) A What is the theoretical yield (in moles) of copper (II) hydroxide when 100mL of 0 125M CuCl2 is combined with 100 mL of 0 230M NaOH? I got 0 0115 mol Cu (OH)2 B What is the concentration (M) of each anion in solution after the reaction is complete? I got 0 125 M for Cl I know that
Question #bcaa2 + Example - Socratic Or, relative to benzene, the present OH is an electron-donating group, which donates electron density into the aromatic ring, away from the proton That makes the hydroxyl proton more partially positive than in benzene, whose hydrogens are all belonging to the aromatic ring That means it's more acidic, and so phenol is more prone to deprotonation than benzene As a note, the pKa of benzene is
