Answer:
120.44 × 10²³ molecules
Explanation:
Given data:
Moles of C₃H₈ = 5.0 mol
Molecules of water produced = ?
Solution:
Chemical equation:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
Now we will compare the moles of C₃H₈ and water.
C₃H₈ : H₂O
1 ; 4
5 : 4×5 = 20 mol
Molecules of water:
1 mole = 6.022 × 10²³ molecules
20 mol×6.022 × 10²³ molecules / 1 mol
120.44 × 10²³ molecules
Answer:
The answer is a carbon isotope.
Explanation:
Carbon has 6 protons and electrons so the atom is neutral.
However it is a carbon isotope because it has more neutrons than protons so be aware of that
Answer:
4, 16,
Explanation:
SI2 is sulphur diiodide. Sulphur is in group sixteen (six valence electrons) while iodine is in group 17(seven valence electrons).
Since there are two iodine atoms and one sulphur atom, the molecule has twenty valence electrons. Out of these twenty valence electrons, only four are bonding electrons. The other sixteen electrons include the four nonbonding electrons found on sulphur and the twelve non bonding electrons found on the two iodine atoms having six nonbonding electrons each.
