Answer:
9 Moles
Explanation:
C2H6 has 6 Hydrogens and Water Has 2 Hydrogens
so it takes 1 mole ethane to produce 3 moles water
1 Mole Ethane ----> 3 Moles Water so 3 ----> 9 moles
Answer: 0.2885J/g°c
Explanation:
Loss of heat of metal = Gain of heat by the water
Therefore
-Qm = +Qw
Where
Q = mΔTCp
Q = heat
M= mass
ΔT = T.f - Ti
Ti= initial temperature
T.f= final temperature
Cp= Specific heat (m is metal, w is water)
-Qm = +Qw
-[m(T.f-Ti)Cpm] = m(T.f-Ti)Cpw
Therefore
-[83.2g(28.42-90.31)Cpm] = 41.82g(28.42-
19.93)4.194J/g°c
Cpm = 1485.54÷ 5149.25
Cpm = 0.2885J/g°c
Therefore , the specific heat of the metal is 0.2885J/g°c
Triangle ADC is also a right triangle, with D the right angle, and AC the hypotenuse.
The triangles are similar (right triangles which share an angle (A), so...
AD/AC = AC/AB 5/6 = 6/AB AB = 6*6/5 = 36/5 = 7.2
Answer:
The ranking order of the degree of polarity is HF>HCl>HBr>HI
Explanation:
The degree of polarity of a compound depends on the nature electronegative atom that it contains.
Among Fluorine,chlorine,bromine and iodine the electronegativity of fluorine is highest among all the mentioned atoms.
Due to high electronegativity HF is the most polar than HCl,HBr and HI and the HI have least polarity as its atomic structure is large and electronegativity is lower than fluorine,chlorine and bromine.
