19) Which associated with the following could have the greatest boiling-point A) HOCH2-CH2OH C) CH3CH3 19) B) CH3CH2OH D) CH3OCH3 20) Which associated with the after statements does work about intermolecular causes of destination between. particles 20) A) they have a tendency to carry particles collectively. B) The solidification of a substance typically needs reduced conditions compared to the way it is of liquefaction. C) Cooling accounts for the materials liquefaction. D) every one of the overhead tend to be real 21) 21) Which associated with the after is a good example of a weak electrolyte B) HNO3 D) MgCl2 A) HC2H302 9 NagCO3 22) k/bond 9 16 22) the potency of an O-H relationship is mostly about corresponding to D) 100 A) 400 B) 50 23) 23) Which associated with the following could have the cheapest boiling-point B) CH CH2OH A) CH3CH3 C) HOCH2-CH2OH D) CH3OCH3 24) 24) Which associated with the after sublimes D) mothballs 9 sugar A) metal B) margarine 25) Which associated with the three levels of matter (solid, fluid, or fuel) has actually particles divided because of the the very least quantity of length A) fuel B) fluid C) solid D) The split length is mostly about the exact same in every three levels 25) 26) which of the substances will occur in option just as particles B) NH4OH 26) 9 CHgNH2 D) CH3OH LIOH in liquid decreases as heat increases. 9 solids 27) 27) generally, the solubility of A) fluids B) fumes D) not one of the 28) The change of air and skin tightening and into the lung area is a good example of which legislation concerning 28) fumes A) Avogadros legislation ) Boyles legislation B) Henrys legislation D) Charles legislation 29) For a great fuel, which sets associated with the factors here are inversely proportional every single presuming all the other factors tend to be held continual 29) 9 V and P A) V and n B) P and n D) V and T 30) stress has actually a big result just regarding solubility of in fluids 9) fuel 30) D) all preceding A) fluid B) solid B-3
19) right here ethane 1,2 diol has actually greatest boiling-point (198 c) therefore
ans is A.Here since the molecular dimensions increases intermolecular causes
in addition increases causes increased boiling-point.
20) ans is D
21)a poor electrolyte is material which will not totally in
its aqueous option.right here the ans is A(acetic acid)
22)right here the potency of OH relationship is about 400 kj/bond ans is
A
23)right here ethane has actually cheapest boiling point(-89c) when I explained in
19 concern so ans is A
24)sublimation is the method by which solid straight converts
into its vapor kind without fluid stage.inside provided substances
moth balls have actually this home so ans D
25)right here your order length involving the particles has
gas>liquid>solid therefore the very least quantity of length sometimes appears in solid
ans C
26)right here the ans is D because all the other substances go through
ionization within their option kind
27)right here since the heat advances the solubility of fumes in
liquid reduces therefore ans is B
28) right here the ans is henrys legislation
29)right here the best fuel equation is PV=nRT whenever we held nRT continual
P and V factors tend to be inversely proportional
30)pressure results solubility of fumes in fluids so ans is
C
