Zorluk: KolayChemical Reactions and Compounds

In chemistry, chemical reactions are categorized by the pattern in which reactants rearrange to form new substances. Match each chemical reaction equation with its correct classification type.

  • 2H2O2→2H2O+O22H_2O_2 \rightarrow 2H_2O + O_2Decomposition reaction
  • C3H8+5O2→3CO2+4H2OC_3H_8 + 5O_2 \rightarrow 3CO_2 + 4H_2OCombustion reaction
  • HCl+NaOH→NaCl+H2OHCl + NaOH \rightarrow NaCl + H_2ONeutralization reaction

Cevap

The reaction 2H2+O2→2H2O2H_2 + O_2 \rightarrow 2H_2O matches Synthesis reaction; 2H2O2→2H2O+O22H_2O_2 \rightarrow 2H_2O + O_2 matches Decomposition reaction; C3H8+5O2→3CO2+4H2OC_3H_8 + 5O_2 \rightarrow 3CO_2 + 4H_2O matches Combustion reaction; and HCl+NaOH→NaCl+H2OHCl + NaOH \rightarrow NaCl + H_2O matches Neutralization reaction.
Each chemical reaction matches its respective classification based on the fundamental pattern of atomic rearrangement: synthesis combines multiple reactants into one product; decomposition splits a single reactant into multiple products; combustion oxidizes a fuel with oxygen to form carbon dioxide and water; and neutralization combines an acid with a base to produce salt and water.

Adım Adım Çözüm

1
Analyze the number and structure of reactants and products in 2H2+O2→2H2O2H_2 + O_2 \rightarrow 2H_2O.
Two distinct reactant molecules join together to form a single product species (H2OH_2O).
When multiple simple reactants unite into a single compound (A+B→ABA + B \rightarrow AB), the process is classified as synthesis.
2
Examine the reactant and products in 2H2O2→2H2O+O22H_2O_2 \rightarrow 2H_2O + O_2.
A single reactant species (H2O2H_2O_2) splits into two distinct product species (H2OH_2O and O2O_2).
When one complex substance breaks apart into simpler components (AB→A+BAB \rightarrow A + B), the process is classified as decomposition.
3
Examine the chemical species participating in C3H8+5O2→3CO2+4H2OC_3H_8 + 5O_2 \rightarrow 3CO_2 + 4H_2O.
A hydrocarbon fuel (C3H8C_3H_8) reacts rapidly with oxygen gas (O2O_2) to yield CO2CO_2 and H2OH_2O.
Oxidation of a hydrocarbon fuel producing carbon dioxide and water vapor is the hallmark of a combustion reaction.
4
Identify the nature of the reactants in HCl+NaOH→NaCl+H2OHCl + NaOH \rightarrow NaCl + H_2O.
An acid (HClHCl) reacts with a strong base (NaOHNaOH) to produce an ionic salt (NaClNaCl) and liquid water (H2OH_2O).
An acid-base double replacement yielding salt and water is specifically classified as a neutralization reaction.
