2H₂ + O₂ = 2H₂O
H₂ hydrogen molecule
O₂ oxygen molecule
Answer:
NO₃⁻.
Explanation:
- Spectator ions are the ions that is present in the same form on both sides of a chemical equation (do not change).
For the reaction: Mg(s) + Zn²⁺ + 2NO₃⁻ → Mg²⁺ + 2NO₃⁻ + Zn(s),
- The reactants' side contains two ions
: Zn²⁺ and NO₃⁻.
- Also, the product's side also contains two ions
: Mg²⁺ and NO₃⁻.
<em>Because the nitrate anions are present on both sides of the equation, they are spectator ions.</em>

Explanation:
Answer:
The answer to your question is:
a) 3.87 mol of CO2
b) 14.63 mol of O2
Explanation:
2C4H10(g) + 13O2(g) → 8CO2(g) + 10H2O(g)
a)
CO2 = ?
Butane 0.968 moles
From the balance equation 2 moles of butane ---------- 8 moles of CO2
0.968 moles of butane ------ x
x = (0.968 x 8) / 2
x = 3.87 moles of CO2
b)
moles O2 = ?
butane = 2.25 mol
From the balance equation
2 moles of butane ---------- 13 mol O2
2.25 mol ---------- x
x = (2.25 x 13) / 2
x = 14.63 mol of O2
