I hope my photo helps. since oxygen goes from a charge of 0 to -2, it gains electrons because electrons have a negative charge. nitrogen goes from 0 to +2 meaning that it is losing electrons to make it a positive charge.
Yes your answer is correct the answer is 1.26
solution is moles=mass/molar mass =98.3/78=1.26
In astronomy, Kepler's laws of planet motion are three scientific laws describing the motion of planets around the Sun, published by Johannes Kepler between 1609 and 1619.
Amino Acids- To build proteins.
Hydrochloric Acids- Help humans digest foods.
Explanation:
When an electron absorbs the light it jumps from its lower energy state towards the higher energy state. This known as absorption.
When an electron come backs from higher energy to lower energy level energy is released emitted out in the form of light. This is known as emission.
1) n = 3 to n = 5 ,This transition will be absorption.
2) n = 1 to n = 3 ,This transition will be absorption
3) n = 3 to n = 2 ,This transition will be emission.
4) n = 2 to n = 1 ,This transition will be emission.
