The mass number and atomic number of the lithium atom are
shown by the symbol 3 7 Li. What is the correct symbol for the
lithium-ion in lithium chloride? A) 2 6 Li- B) 3 6 Li+
C) 3 7 Li+
D) 3 7 Li- - ANSWER-C; loss of electron dosent affect RAM.
All of the following can act as Brønsted-Lowry acid (proton
donors) in aqueous solution except:
A) HI
B) HCO3 -
C) H2S
D) NH3 - ANSWER-D ; Only compound that is able to accept
electrons without donating them
All of the following statements about carbon dioxide are true
except:
A) it can be prepared by the action of acid on limestone
B) it is used to extinguish fires
C) it dissolves in water at room temperature
,D) it sublimes rather than melts at 20°C and 1 atmosphere
pressure -
ANSWER-D
Which of the options will form the major product ?
- primary carbocation
- secondary carbocation
- tertiary carbocation - ANSWER-- TERTIARY CARBOCATION
BECAUSE IT IS
MORE STABLE
True or false , alcohols do not react with NaOH ? - ANSWER-
true , they do not
react with NaOH and thus no salt
is formed
Which of the reaction shown below involves the formation of an
ionic precipitate from a solution?
A) Ca2+ + CO3 CaCO3
B) HCO3 - + H+ H2CO3
C) Fe + Cu2+ Fe2+ + Cu
D) CaCO3 + H2CO3 Ca(HCO3)2 - ANSWER-A ; because a
precipitate is formed when a cation and an anion react.
Given the following process that has reached equilibrium: NaCl
(s)-><- NaCl (aq). For the phase equilibrium to exist, the NaCl
(aq) must be a solution that is:
A) concentrated
B) saturated
,C) supersaturated
D) unsaturated - ANSWER-B ; Since only a saturated solution
would mean that
there is a balance in concentrations in the system
Glucose and fructose
are:
A)
enantiomers
B) functional
isomers
C)
tautomers
D) chain isomer - ANSWER-Functional
Isomers
Which of the following is an observable property of many
acids?
A) they become slippery when reacting with water
B) they react with metals to release hydrogen gas
C) they produce salts when mixed with other acids
D) they become more acidic when mixed with a base -
ANSWER-B
All of the native α-amino acids can react with the reagents
below except:
A)
NaOH
, B)
FeCl3
C) l
HC
D) glycine -
ANSWER-B
For the system at equilibrium 2 SO2 (g) + O2 (g) 2 SO3 (g) +
heat, decreasing the temperature increases the number of
moles of which of the following when equilibrium is
reestablished?
A) SO3 (g)
B) O2 (g)
C) SO2 (g)
D) both, O2 (g) and SO2 (g) - ANSWER-A
Which substance releases hydrogen when it reacts
with steam?
A) l
A
B)
Li
C)
CH3OH
D) H2S - ANSWER-B ; li + 2h20 ->
lioh +h2
The reagent than can be used to distinguish between pentanal
and pentanone is
