Answer: if you think about a tree the older rings would be in the middle, so you’d find objects with older age below/under/inside
Answer:
n = 1.24 moles
Explanation:
Given that,
Mass = 153 grams
Molar mass of KClO₃ = 122.55 g/mol
We need to find the number of moles.
We know that,
No. of moles = given mass/molar mass
So,
So, there are 1.24 moles in 153 g of KClO₃.
Answer is: quantity of sulfur is 13 tons.
Chemical reaction: S(s) + O₂(g) → SO₂(g).
From chemical reaction: n(S) : n(SO₂) = 1 : 1.
n(S) = n(SO₂); amount of substance.
m(S) ÷ M(S) = m(SO₂) : M(SO₂).
m(S) : 32 g/mol = 26 t : 64 g/mol.
m(S) = (32 g/mol · 26 t) ÷ 64 g/mol.
m(S) = 13 t = 13000 kg; mass of sulfur.
