Answer:
2 moles of NO
Explanation:
Our reaction is:
4NH₃ + 5O₂ → 6H₂O + 4NO
4 moles of ammonia react to 5 moles of oxygen in order to produce 6 moles of water and 4 moles of NO
We need to determine the limiting reactant:
Ratio is 4:5, As 4 moles of ammonia react to 5 moles of oxygen and we have 4 moles, we definetely need 5 moles, but the problem is, we only have 2.5 moles of O₂. Oxygen is the limting reagent.
5 moles of O₂ produce 4 moles of NO, according to stoichiometry
2.5 moles of O₂ may produce (2.5 . 4) / 5 = 2 moles of NO

Answer:
We typically represent covalent bonds with a dash ( - ) between the atoms. This indicates a single bond. Ex: Cl - Cl
Single bond, double bond, triple bond.
Explanation:
We call it a single covalent bond because the atoms are sharing a single pair of electrons.
Answer:
Number of moles of EDTA added 36.66 × 10⁻⁵ mol.
Explanation:
Given data:
Volume of solution = 0.012 mL
Molarity of solution = 30.55 mole/ L
Number of moles =?
First of all we will convert the given solution in liter.
1 L = 1000 mL
0.012/1000 = 1.2 × 10⁻⁵ L
Formula:
Molarity = number of moles / volume of solution
Number of moles = molarity × volume of solution
Number of moles = 30.55 mol/L × 1.2 × 10⁻⁵ L
Number of moles = 36.66 × 10⁻⁵ mol
