For a p type of semiconductor we need a dopant which is from 13th group in periodic table
Al , B, Ga, In Tl
So the correct element will be In : Indium
The other elements belongs to 15th group and hence will give n type semiconductor
Answer:
the standard cell potential value
Explanation:
For every cell, we can calculate its standard electrode potential from the table of standard electrode potentials listed in many textbooks.
However, from Nernst's equation;
Ecell= E°cell - 0.0592/n log Q
Hence the standard cell potential (E°cell) affects the value of the calculated cell potential Ecell from Nernst's equation as stated above.
Answer:
I have no clue at all im in 11 and dont know anything lol byeeee
Explanation:um um i am lost
Answer:
0.225 atm
Explanation:
v1=450ml÷1000=0.45l(1l=1000ml)
P1=1
v2=2.00l
p2=?
p1v1=p2v2
p2=p1v1/v2
=1×0.45/2
=0.225
so the answer is first one
What is called compound?
- In chemistry, a compound is a substance made up of two or more different chemical elements combined in a fixed ratio.
- When the elements come together, they react with each other and form chemical bonds that are difficult to break.
- These bonds form as a result of sharing or exchanging electrons between atoms.
a) Mg(OH)2 or Ni(OH)2.
Mg(OH)2 1.8×10–11
Ni(OH)2 2.0×10–15
Clearly, Ksp value for Mg(OH)2 is higher , meaning it is MUCH MORE SOLBULE than Nickel
therefore, choose Mg(OH)2.
b)
PbS 3×10–28
CuS 6×10–37
Clearly, PbS is much more soluble than CuS
since Ksp is higher .
c)
Ag2SO4 1.4×10–5
MgF2 3.7×10–8
Clearly, Ag2SO4 has higher Ksp, so it is much more soluble.
