Answer:
Chemical equation: NH₃(g) + O₂(g) → NO(g) + H₂O(l).
Oxidation reaction: N⁻³ → N⁺² + 5e⁻ /×4.
Reduction reaction: O₂⁰ + 4e⁻ → 2O⁻² /×5.
Oxidation reaction: 4N⁻³ → 4N⁺² + 20e⁻.
Reduction reaction: 5O₂⁰ + 20e⁻ → 10O⁻² /×5.
Balanced chemical equation: 4NH₃(g) + 5O₂(g) → 4NO(g) + 6H₂O(l).
Ammonia (NH₃) reacts with oxygen (O₂) and form nitrogen(II) oxide (NO) and water (H₂O). Catalyst is this reaction is platinum (Pt).
This is combustion reaction.
Answer:
K = K1×K2 = [CO2] [H2]⁴ / [H₂O]² [CH4]
Explanation:
Based on the reactions:
CH2 (g) + H2O(g) ⇄ CO (g) + 3H2 (g) K1
CO (g) + H2O (g) ⇄ CO2 (g)+H2(g) K2
The sum of both reactions is:
CH4 (g)+2H2O (g) ⇄ CO2(g)+4H2(g) And K of the reaction is: K = K1×K2
K is defined as the ratio between concentrations of products and reactans. Each compound must be elevated to its coefficient in the reaction. That is:
<h3>K = K1×K2 = [CO2] [H2]⁴ / [H₂O]² [CH4]</h3>
Answer:
72.6 grams
Explanation:
I got this answer through stoichiometry. For every 1 mole of Mg, 2 moles of CuBr are consumed. Because of this, multiply the moles of Mg by 2. Then, convert moles to grams.
Answer: Density and the elements that it composes.
Explanation: The elements that form the mineral and the size of atoms of these minerals is what ultimately matters in the determination of the size the mineral will be.
