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
Question #6b9a2 - Socratic In order to answer these questions we first need to know the equation representing this chemical reaction In this case, it is a reaction between HCl and Ca (OH)2: Ca (OH) 2 + HCl → CaCl 2 +H 2 O Let's balance the equation: Ca (OH) 2 + 2 HCl → CaCl 2 + 2 H 2 O a Using the formula n = m M: ⇒ n(Ca (OH)) = 0 75 g 74 10 g mol−1 ⇒ n(Ca (OH)) = 0 01 mol In the balanced chemical equation
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
Why does neutralisation of any strong acid in an aqueous . . . - Socratic Because its the same reaction A monobasic [monoprotic] acid like HCl has one H atom, which fully dissociates to form a hydrogen ion, H^+ The strong alkali fully dissociates to forman hydroxide ion OH^-, which react to from water This is the ionic equation for neutralisation and occurs for all strong acid strong alkali reactions
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
