As we know methane is an Alkane to separate an Alkane We use fractional distillation to put each liquid into its fraction with the right temperature group
number of moles = 1.00 X 10^22 ÷ 6.022 × 10^23
= 0.0166 moles
mass = number of moles × molar mass
= 0.0166 × 120.37 = 2.00 g
Therefore is very important because it ensures survival, existence and stability of the environment.
Answer:
WATER
Explanation:
The another name for dihydrogen monoxide is water
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.
