C. Protons, neutrons, electrons
The number of moles left = 0.0067 moles
<h3>Further explanation</h3>
Given
0.28 g CO
2 x 10²¹ molecules removed
Required
Number of moles left
Solution
Initial mol of CO(MW=28 g/mol) :
mol = 0.28 : 28
mol = 0.01
The number of molecules in 0.01 mol :
= 0.01 x 6.02 x 10²³
= 6.02 x 10²¹
2 x 10²¹ molecules removed, so molecules left :
= 6.02 x 10²¹ - 2 x 10²¹
= 4.02 x 10²¹
moles of 4.02 x 10²¹ :
= 4.02 x 10²¹ : 6.02 x 10²³
= 0.0067 moles
Carbon dioxide, water;then energy source in sunlight and chlorophl maybe
Balanced chemical reaction: C₃H₈(g) + 5O₂(g) → 3CO₂(g) + 4H₂O(g).
<span>There are same number
of atoms of on both side of balanced chemical reaction: ten oxygen atoms, three carbon atoms and eight hydrogen atoms.
</span>Carbon is oxidized and oxygen is reduced in this balanced chemical reaction of combustion of propane.
