when balanced, which equation would have the coefficient 3 in front of any of the reactants?\no zn + hcl → zncl₂ + h₂\no h₂so₄ + b(oh)₃ → b₂(so₄)₃ + h₂o\no fe + agno₃ → fe(no₃)₂ + ag\no c₂h₄o₂ + o₂ → co₂ +h₂o
Answer
Explanation:
Step1: Balance the first equation
$Zn + 2HCl\rightarrow ZnCl_{2}+H_{2}$, no coefficient of 3 for reactants.
Step2: Balance the second equation
$3H_{2}SO_{4}+2B(OH){3}\rightarrow B{2}(SO_{4}){3}+6H{2}O$, coefficient of 3 for $H_{2}SO_{4}$ (a reactant).
Step3: Balance the third equation
$Fe + 2AgNO_{3}\rightarrow Fe(NO_{3})_{2}+2Ag$, no coefficient of 3 for reactants.
Step4: Balance the fourth equation
$C_{2}H_{4}O_{2}+2O_{2}\rightarrow 2CO_{2}+2H_{2}O$, no coefficient of 3 for reactants.
Answer:
$H_{2}SO_{4}+B(OH){3}\rightarrow B{2}(SO_{4}){3}+H{2}O$
