Answer:
Because number of electrons becomes greater than protons and atom form anion.
Explanation:
In order to understand this problem we must know about anion and cation.
Anion:
When an atom gain the electrons anion is formed. The negative sign shows that atom gain electron because number of electron are greater than protons or we can say that negative charge becomes greater than positive charge.
Cation:
When atom lose electron cation is formed. The atom thus have positive charge because number of positive charge i.e protons are increased are greater than negative charge or electron.
In given problem N gain three electrons which means negative charge becomes greater that's why the extra electron gained by atoms are written as -3.
Answer:
1) B. increases
2) B. greater
3) C. Both A and B are correct
4) Activation energy
Explanation:
The rate of a chemical reaction is depend on temperature. If temperature increases, the chemical reaction also increases and vice versa. Fast reaction means which is completely in less time. So atoms in fast reaction have great activation energy and slow reaction have less activation energy. Collision occurs when the particles have energy to move and they collide in proper direction.
Answer:
the enantiomeric excess of the mixture is 40%
Explanation:
The computation of the enantiomeric excess of the mixture is shown below:
As we know that
Hence, the enantiomeric excess of the mixture is 40%
Waves with higher frequencies have shorter wavelengths, and lower frequencies have longer wavelengths
