The size of atom reduces
Electronic configuration of sodium -
2,8,1
In order to become stable it loses one electron and becomes positive ion.
It's size reduces.
Answer:
Sodium chloride and hydrogen gas are the products of this reaction. If the gas collected has a pressure of 1.05 atm at 298 K, then what volume is the hydrogen
Explanation:
Answer:
375.2 kJ
Explanation:
- H₂(g) +F₂(g) → 2HF(g) +536kJ
The information the equation above provides lets us know that when 2 mol of hydrogen fluoride (HF) are produced, 536 kJ of energy (as heat) is produced.
We can then <u>state a rule of three</u>:
And <u>solve for X</u>:
- X = 1.4 mol * 536 kJ / 2 mol
The answer is Decomposition.
