chemical reactions\nidentify the reactants and products in the following table. also indicate whether the following reaction is balanced or unbalanced. to know if it is balanced, see if you have the same number of elements on the reactant and product side (for example, in the first problem, there are four hydrogens on both sides and two oxygens on both sides, so it is balanced. for the second one, there is one na on the reactant side and two on the product side, so it is unbalanced)\nequations reactants products balanced or unbalanced equation\n2h₂ + o₂ → 2h₂o\nna + o₂ → na₂o\nn₂ + h₂ → nh₃\np₄ + 5o₂ → p₄h₁₀\nfe + ho₂ → feo₂ + h₂o\nno₂ + ch₃ → co₂ + nh₃
Answer
Explanation:
Step1: Identify reactants and products for $2H_2 + O_2\rightarrow2H_2O$
Reactants are $2H_2$ and $O_2$, products are $2H_2O$. Counting atoms: 4 H and 2 O on both sides, so balanced.
Step2: Identify reactants and products for $Na + O_2\rightarrow Na_2O$
Reactants are $Na$ and $O_2$, products are $Na_2O$. 1 Na on reactant side, 2 Na on product side, unbalanced.
Step3: Identify reactants and products for $N_2 + H_2\rightarrow NH_3$
Reactants are $N_2$ and $H_2$, products are $NH_3$. 2 N on reactant side, 1 N on product side, unbalanced.
Step4: Identify reactants and products for $P_4+5O_2\rightarrow P_4H_{10}$
Reactants are $P_4$ and $5O_2$, products are $P_4H_{10}$. There is no H on reactant side and H on product side, unbalanced.
Step5: Identify reactants and products for $Fe + HO_2\rightarrow FeO_2 + H_2O$
Reactants are $Fe$ and $HO_2$, products are $FeO_2$ and $H_2O$. Unbalanced as atom counts don't match.
Step6: Identify reactants and products for $NO_2+CH_3\rightarrow CO_2 + NH_3$
Reactants are $NO_2$ and $CH_3$, products are $CO_2$ and $NH_3$. Unbalanced as atom - counts don't match.
