answer: A not sure but i hope it helps :) success
To be able to answer this equations, we must set given information. Suppose the reaction to yield NO is:
N₂ + O₂ → 2 NO
Next, suppose you have 1 g of each of the reactants. Determine first which is the limiting reactant.
1 g N₂ (1 mol N₂/ 28 g)(2 mol NO/1 mol N₂)= 0.07154 mol NO present
Number of molecules = 0.07154 mol NO(6.022×10²³ molecules/mol)
<em>Number of molecules = 4.3×10²² molecules NO present</em>
6.28 mol O2 × 2 mol h2 / 1 mol 02 = 12.56 moles h2
Answer:
The answer to your question is letter C. 3
Explanation:
Unbalanced chemical reaction
C₂H₄ + O₂ ⇒ CO₂ + H₂O
Reactants Elements Products
2 C 1
4 H 2
2 O 3
Balanced chemical reaction
C₂H₄ + 3O₂ ⇒ 2CO₂ + 2H₂O
Reactants Elements Products
2 C 2
4 H 4
2 O 6
The coefficient of Oxygen is three.
