- Question #22e51 - Socratic
Products formed are; Cu (OH)_2 + HCl -> CuCl_2 + H_2O Since CuCl_2 is soluble in water But; Cu (OH)_2 + HCl -> CuCl_2 + H_2O " [Not Balanced]" Balancing the equation
- Question #645c9 - Socratic
How about these? > (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" →
- Question #93f99 - Socratic
The molarity of the acid is 1 434 Start with the equation: 2HNO_ (3 (aq))+Ca (OH)_ (2 (aq))rarrCa (NO_3)_ (2 (aq))+2H_2O_ ( (l)) This tells us that 2 moles of HNO_3
- Question #ccabf - Socratic
Because N aOH → N a+ + OH − and N i2+ + 2OH −→N i(OH)2 Total Mols of N aOH: 60mL ⋅ 0 45M ol L = 27mM ol of N aOH (dont forget the m for milli=one thousandth) This will produce 27 2 = 13 5mM ol of N i(OH)2 Now you multiply this by the molecular mass number to get the weight in milligrams (divide by 1000 to get the grams) Nickel (II)hydroxide may be formed without or (more likely

- Question #f84c2 - Socratic
Cr (OH)_3 (s)rightleftharpoonsCr^ (3+) + 3HO^- Where K_"sp"= [Cr^ (3+)] [HO^-]^ (3) But we have been given [HO^-]=4xx10^-6*mol*L^-1 Now for a saturated solution, WE KNOW from the stoichiometry that [Cr^ (3+)]=1 3 [HO^-]
- Question #e1140 + Example - Socratic
Step 1 is a simple OH proton transfer Such reactions are fast, with rate constants ranging from 10^4 to 10^9 "L·mol"^-6"s"^ (-1) Step 2 is the addition of an anion to a cation to form a neutral molecule
