- 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
- In an aqueous solution containing 1. 0 M NH_4Cl (K_a . . . - Socratic
In an aqueous solution containing 1 0 M NH4Cl (K a = 5 56 × 10−10), what is the solubility of Mg(OH)2? K sp = 5 5 × 10−11
- 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
- 2. 5x10-3 moles of solid Mg (OH)2 is added to a 100. 0 mL . . . - Socratic
2 5x10-3 moles of solid Mg (OH)2 is added to a 100 0 mL sample of 0 250 M aqueous chlorous acid solution Ignore the volume change associated with the added solid Find the pH of the solution?
- 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
