Answer:
increase in temperature of the intrinsic semiconductor
Explanation:
- If the p-side has a higher doping concentration, it implies that number of holes (positive ion) increased which is greater than number of electron (negative ion) in the n-side
- in order to balance the intrinsic concentration, that is to balance the number of holes and electrons which depends on temperature.
- an increase in the temperature of the intrinsic semiconductor (p-side), increases the number of electron but number of holes remains constant.
A balance in the intrinsic concentration helps in tuning to the same radio channel.
The number is 25. The square root of 25 is 5 and 5x2 is 10 and then 10+5 is 15
Answer:
First, balance the half-reactions
Second, equalize the electrons
Third,add two reaction equations to get final answer
Explanation:
For example
H₂C₂0₄ + MnO⁻₄ ---------->CO₂+Mn²⁺
(i) Balancing the half reactions
H₂C₂O₄-------->2CO₂+2H⁺+2e⁻
5e⁻ +8H⁺+MnO₄⁻----------->Mn²⁺+4H₂O
(ii)
Equalizing the electrons
5H₂C₂O₄--------->10CO₂+10H⁺+10e⁻ ---here there is a factor of 5
10e⁻+16H⁺+2MnO₄⁻--------->2Mn²⁺+8H₂O -----here there is a factor of 2
(iii)
Add the two where electrons and some Hydrogen ions will cancel out
5H₂C₂O₄+6H⁺+2MnO₄⁻---->10CO₂+2Mn²⁺+8H₂O
Ice has a lower density than the density of water.
