The chemical formula for table sugar is C12H22O11. From the formula, you can say that it is an organic molecule where in every molecule contains 12 atoms of carbon, 22 atoms of hydrogen and 11 atoms of oxygen. There are 45 atoms in total in one molecule of sugar.
False, Atoms are the smallest units of matter that display both the chemical and physical properties of it, based on the structure of the atom.
Answer:
5.12 molecules of Ag₂S could be produced from 10 molecules of silver.
Explanation:
Given data:
Molecules of Ag = 10 molecules
Molecules of Ag₂S = ?
Solution:
First of all we will convert the number of molecules into gram.
10/ 6.022 ×10²³ = 1.7 × 10⁻²³ mol
Mass of Ag:
Number of moles = mass/ molar mass
Mass = Number of moles × molar mass
Mass = 1.7 × 10⁻²³ mol × 107.9 g/mol
Mass = 183.43 × 10⁻²³ g
Chemical equation:
2Ag + H₂S → Ag₂S + H₂
Now we will compare the moles of silver with Ag₂S from balanced chemical equation.
Ag : Ag₂S
2 : 1
1.7 × 10⁻²³ : 1/2 ×1.7 × 10⁻²³ = 0.85 × 10⁻²³ mol
Molecules of Ag₂S:
0.85 × 10⁻²³ × 6.022 ×10²³ = 5.12 molecules
Answer:
I think it might be a closed system
6 miles of H2O is equal to 12 Hydrogen molecules and 6 oxygen molecules. Equaling 18 in total.
