Understanding oh no our table it s broken fnf requires examining multiple perspectives and considerations. How many grams of \text {NH}_4\text {OH} do I need to make ... "6.3072 g" >>"Molarity" = "Moles of solute"/"Volume of solution (in litres)" "0.45 M" = "n"/"0.4 L" "n = 0.45 M × 0.4 L = 0.18 mol" You need "0.18 mol" of "NH"_4"OH" Molar mass of "NH"_4"OH" is "35.04 g/mol" Mass of solute = 0.18 cancel"mol" × "35.04 g"/cancel"mol" = "6.3072 g" Question #71ce2 - Socratic. H^+ + OH^--> H_2O when the acid was added to the resulting solution. The H^+ and OH^- react in a 1:1 ratio. This tells us that the number of moles of H^+ used will be equal to the number of OH^- moles in solution.
Likewise, 2 moles of lithium produces 2 moles of OH^-. This is also a 1:1 ratio. Can you give the IUPAC name for the following (CH_3)_3C-OH ...
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. Another key aspect involves, both names seem to be unambiguous. Is it necessary to have oh group of phenol valways at ortho ... No, the "OH" group in phenol is by definition at "C1". > The structure of phenol is You can draw the structure like this: phenol2 However, the structure is not meta-phenol.
It is phenol because the ring carbon attached to the "OH" group is now "C1". The "OH" carbon can be on any carbon atom of the ring, and the compound is still phenol, On the hydrolysis of esters according to the reaction: HCOO ... HCOO^(-)(aq) + H_2O(l) rightleftharpoons HCOOH(aq) + OH^(-)(aq) If the solution is diluted, the reaction will shift left, because (i) water isn't in the equilibrium expression, and (ii) each product is in aqueous solution.
In this context, if NaOH is added, then we have increased the concentration of hydroxide ions. The reaction will shift left to re-equilibrate and consume the excess OH^-. Similarly, pressure will have ...
> (a) With "HCN" The "HCN" adds across the α "C=O" group to form a cyanohydrin. underbrace ("CH"_3"COCOOH")_color (red) ("pyruvic acid") + "HCN" → ... We want the standard enthalpy of formation for Ca (OH)_2. Thus, our required equation is the equation where all the constituent elements combine to form the compound, i.e.: Ca +H_2+O_2->Ca (OH)_2 Let us now write down the given equations: [The first equation mentioned is incorrect, and so I have revised it.] (1) 2H_2 (g) + O_2 (g)->2H_2O (l) and DeltaH_1=-571.66 kJmol^-1 (2) CaO (s) + H_2O (l ...
Similarly, the sodium ions remain in solution as spectator ions. If XS sodium hydroxide is added the precipitate redissolves to give the soluble plumbate (II) ion. A simple way of writing this is: (chemguideUK) Ammonia solution can't do this as the concentration of OH^ (-) ions is not high enough. Equally important, calculate moles of Acid, calculate moles of Base. subtract, #OH^-# should be in excess, calculate Molarity of #OH^-# , pOH = -log (#OH^-#), then 14-pOH = pH
