Answer:
Atomic Number = 3.
Explanation:
The number of protons determines the atomic number. Basically the number of protons is the exact same as the atomic number.
Protons 3 = Atomic number 3
Answer:
Mass of 
produced = 32 g
Explanation:
Calculation of the moles of 
as:-
Mass = 82.4 g
Molar mass of = 122.55 g/mol
The formula for the calculation of moles is shown below:
Thus,
From the reaction shown below:-
2 moles of potassium chlorate on reaction forms 3 moles of oxygen gas
So,
0.67237 moles of potassium chlorate on reaction forms 
moles of oxygen gas
Moles of oxygen gas = 1 mole
Molar mass of oxygen gas = 32 g/mol
<u>Mass of produced = 32 g</u>
Answer:
Sodium reacts with the oxygen in air to form sodium oxide, and traces of yellowish sodium peroxide. ... Probably, the reaction with atmospheric oxygen will be faster, because I have never seen sodium metal turning whitish on exposure, though it does lose its lustre and and reactivity (just the surface).
Equilibrium
N₂(g) + 3H₂(g) ⇔ 2NH₃(g)
If the concentration of the reactants is added, the system will reduce the concentration of the reactants by shifting towards the products and vice versa if the concentration of the reactants is decreased the system will shift towards the reactants.
ammonia is removed from the reaction mixture ⇒ it means the ammonia is reduced then the equilibrium shifts to the right
