Water resources have been greatly impacted by the use of salt and brine on roads, construction zones, and pesticides through surface runoff. Also, riparian zones (the vegetation around a water source) that help to prevent surface runoff have been cut down to make more room for development.
Answer:
A. 2Cu(s) + S(s) → Cu₂S(s)
B. 2C₈H₁₈(g) + 25O₂(g) → 16CO₂(g) + 18H₂O(g)
C. 2SO₂(g) + O₂(g) → 2SO₃(g)
Explanation:
A. Let's think the reactants:
Cu and S
The product is: CuS
Equation: 2Cu(s) + S(s) → Cu₂S(s)
B. The reactants are:
O₂ and C₈H₁₈
The products are: water and CO₂
This is a combustion reaction: 2C₈H₁₈(g) + 25O₂(g) → 16CO₂(g) + 18H₂O(g)
C. Reactants: SO₂ and O₂
Products: SO₃
Equation: 2SO₂(g) + O₂(g) → 2SO₃(g)
