Answer:
This matters because you need to know if this site is crediable
Explanation:
You need to know this because you need to know who runs this site and if it was approved by anything crediable.
Answer:
2 NO (g) → N2 (g) + O2 (g)
2 NOCl (g) → 2 NO (g) + Cl2 (g)
____________________________
2NOCl (g) ⟶ N2 (g) + O2 (g) + Cl2 (g)
ΔH = [90.3 kJ x 2 x -1] + [-38.6 kJ x -1 x 2] = -103.4 kJ
The ΔH for the reaction is -103.4 kJ
If you look at the periodic table you will see the atomic number (the smaller number) which is 3. that identifies how many protons there are. since the lithium is neutral that means there’s a same amount of electrons.
therefore there’s 3 electrons and 3 protons
Answer:
LiOH + KCl —> LiCl + KOH
Explanation:
LiOH + KCl —> LiCl + KOH
The equation is balanced since we have the same number atoms of the different elements on both side of the equation
Sodium 23 has 11 electrons 11 protons and 12 neutrons
