- 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 chemical formula for lithium hydroxide? - Socratic
LiOH 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) rarr LiOH(aq) + 1 2H_2(g)uarr
- What is the mass percent of hydrogen for C_3H_5OH? - Socratic
In order to compute the mass percent of hydrogen in #C_3H_5OH# we're going to need two things: #color(brown) "1: The formula mass of the entire compound"#
- Whats the pH of 0. 75M barium hydroxid? Ba(OH)^2 - Socratic
Of course, there is a catch and the question does not reflect chemical reality The data I have in my text suggest that we have a saturated solution when #[Ba(OH)_2]=0 27*mol*L^-1# the data here are therefore unreasonable and please alert your chem teacher to the unreality of the question
- What is the value of ΔG°cell? - Socratic
They have a cadmium anode, which is oxidized to Cd(OH)2(s) in a basic background electrolyte of concentrated OH–, and a cathode half-reaction in which NiO(OH)(s) is reduced to Ni(OH)2(s) Cd(OH)2 +2e^- -> Cd +2OH- E^o red = -0 403V
- Can you give the IUPAC name for the following (CH_3)_3C-OH . . . - Socratic
So this is a propanol derivative: "2-methylpropan-2-ol" For "isopropyl alcohol", H_3C-CH(OH)CH_3, the longest chain is again three carbons long, and C2 is substituted by -OH, so "propan-2-ol" I think this is right, and I haven't broken any arcane rule Both names seem to be unambiguous
- 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
- 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
