Answer:
A) { + } Ge-Se { -}
B) { + } Ge-Br { - }
C) { - } Br-Se { + }
Explanation:
The (-)ive sign shall be placed for the atom with higher electronegativity, while the other atom will be electropositive.
a) Electronegativity of Ge = 2.01
Electronegativity of Se = 2.55
{ + } Ge-Se { -}
b) Electronegativity of Ge = 2.01
Electronegativity of Br = 2.95
{ + } Ge-Br { - }
c) Electronegativity of Br = 2.95
Electronegativity of Se = 2.55
{ - } Br-Se { + }
<span> that the reaction is preferably called an elimination, rather than a dehydration, although I personally like the term dehydration because it emphasizes the strong dehydrating power of H2SO4 that is unfotunately forgotten too often by undergraduates. I like to think of it as H2SO4 has such a strong affinity for water that it literally pulls water molecules from organics.</span>
5. The evidence that marker ink is a mixture is that it can be separated into different color pigments.
Answer:
d
Explanation:
evaporation is the process by which liquid mollecules are converted to gaseous mollecules
Answer:
The product of emission of beta particle from uranium 238 will be Uranium 239
Explanation:
There are two type of beta decay
β− decay and β+ decay
Let us assume here the decay is β− decay for Uranium 238
Uranium 238 will decay β− to produce Uranium 239
Hence, the product of emission of beta particle from uranium 238 will be Uranium 239
