The element oxidized is the element in which the charge becomes more positive after the reaction, hence the reducing agent. The element that is reduced is the element or compound in which the charge becomes more negative after the reaction. Sn becomes +4 from +2. Hence Sn is the reduced element while Pb becomes +2 from +4 hence Pb is the element oxidized and PbCl4 is the reducing agent.
Answer:
I think it is 100 if I guess
Answer:
Eg:Salt...Essentially, water moves across a cell membrane to try to equalize the salinity or concentration of salt on both sides of the membrane. If you add enough salt, too much water will be removed from a cell for it to stay alive or reproduce. A high concentration of salt kills organisms that decay food and cause disease.
Explanation:
Answer: n= 3, l= 0 , m= 0 and s=[/tex]\frac{-1}{2}[/tex]
Explanation:
Principle Quantum Numbers : It describes the size of the orbital and the energy level. It is represented by n. Where, n = 1,2,3,4....
Azimuthal Quantum Number : It describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...
Magnetic quantum number : It describes the orientation of the orbital. It is represented as 'm'. The value of m ranges from -l to +l.
Spin quantum number: It describes the spin of the electron. It is represented as 's'. The value of s can be +1/2 or -1/2


Thus electron enters 3s orbital , thus n= 3, l= 0 , m= 0 and s=[/tex]\frac{-1}{2}[/tex]
Answer:
B) microscopic
Explanation:
A scanning tunneling microscope allows imaging of microscopic particles.
