Protons-33
neutrons-42
electrons-33
The answer is -33.6 degree Celsius... or approximately-34 degree Celsius. Firstly, you will change the L to mL so 2.10L to mL is 2100ML.. so if 750ML=-12 degree Celsius then 2100ML is what?? So.. if more less divide.. so 2100ML/750ML *-12 =-33.6 degree Celsius.. approximately -34 degree Celsius. I hope it helped??
Answer:
1. H+ + OH- <--------> H2O
H+ is a Lewis acid
OH- is a Lewis base
2. Cl- + BCl3 <---------> BCl4-
Cl- is a Lewis base
BCl3 is a Lewis acid
3. K+ + 6H2O <------> K(H2O)6+
K+ is a Lewis acid
H2O is a Lewis base
Explanation:
By definition, Lewis acid is an electron pair acceptor while a Lewis base is an electron pair donor.
Potassium ion accept electron pairs from 6 water molecules which donate the electron pairs.
