29 protons, 34 neutrons, and if there is no charge there will be 29 electrons
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.
Metalloids show both metal and non metal properties
Answer:
Measure 20mL of the stock
Explanation:
All we need to do is to find the volume of the stock solution needed. This is illustrated below:
C1 = 2M
V1 =?
C2 = 0.400 M
V2 = 100mL
C1V1 = C2V2
2 x V1 = 0.4 x 100
Divide both side by 2
V1 = ( 0.4 x 100) /2
V1 = 20mL
Therefore, to prepare the solution, we will measure 20mL of the stock solution and make it up to the 100mL mark.
Answer:
C
Explanation:
Exothermic means that heat is released from the reaction
