- 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
- 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
- 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
- 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
- If 50. 0 milliliters of 3. 0 M H_3PO_4 completely . . . - Socratic
If 50 0 milliliters of 3 0 M H3PO4 completely neutralized 150 0 milliliters of Mg(OH)2, what was the molarity of the Mg(OH)2 solution?
- 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
