I BELIEVE THAT VAPORIZATION THAT <span>element or compound is a phase transition from the liquid phase to vapor.
AND
EVAPORATION </span>a type of vaporization of a liquid that occurs from the surface of a liquid into a gaseous phase that is not saturated with the evaporating substance.
Answer: While the mass number is the sum of the protons and neutrons in an atom, the atomic number is only the number of protons. The atomic number is the value found associated with an element on the periodic table because it is the key to the element's identity.

The anode is the metal that is higher on the list because it is more easily oxidized.
Answer:
The of the given reaction is -129.6 kJ
Explanation:
The given chemical reaction is as follows.
Enthalpy of each reactant and products are as follows.
In the given chemical reaction involved two C-H bonds in the reactant side and one C-C bond in the product side therefore, the enthalpy of formation will be the negative.
Therefore, The of the given reaction is -129.6 kJ
Answer:
Mass = 51.12 g
Explanation:
Given data:
Mass of lithium nitride = 32.9 g
Mass of water needed = ?
Solution:
Chemical equation:
Li₃N + 3H₂O → NH₃ + 3LiOH
Number of moles of lithium nitride:
Number of moles = mass/ molar mass
Number of moles = 32.9 g/ 34.83 g/mol
Number of moles = 0.945 mol
Now we will compare the moles of water and lithium nitride.
Li₃N : H₂O
1 : 3
0.945 : 3×0.945 = 2.84 mol
Mass of water:
Mass = number of moles × molar mass
Mass = 2.84 mol × 18 g/mol
Mass = 51.12 g
