drag the tiles to the boxes to form correct pairs. match each chemical reaction with the type of reaction that best describes it. synthesis 2al + 6hcl → 2alcl₃ + 3h₂ decomposition ca + br₂ → cabr₂ single displacement 4nh₃ + 5o₂ → 4no + 6h₂o double displacement 2nacl → 2na + cl₂ combustion fes + 2hcl → fecl₂ + h₂s
Answer
Answer:
synthesis - $Ca + Br_2\rightarrow CaBr_2$ decomposition - $2NaCl\rightarrow 2Na + Cl_2$ single displacement - $2Al + 6HCl\rightarrow 2AlCl_3+3H_2$, $FeS + 2HCl\rightarrow FeCl_2 + H_2S$ combustion - $4NH_3 + 5O_2\rightarrow 4NO + 6H_2O$
Explanation:
Step1: Identify synthesis reaction
A synthesis reaction combines two or more substances into one. $Ca + Br_2\rightarrow CaBr_2$ has two elements combining to form a compound.
Step2: Identify decomposition reaction
A decomposition reaction breaks a compound into two or more simpler substances. $2NaCl\rightarrow 2Na + Cl_2$ is a compound splitting into elements.
Step3: Identify single - displacement reaction
In a single - displacement reaction, one element replaces another in a compound. In $2Al + 6HCl\rightarrow 2AlCl_3+3H_2$, Al replaces H in HCl, and in $FeS + 2HCl\rightarrow FeCl_2 + H_2S$, H replaces S in FeS.
Step4: Identify combustion reaction
A combustion reaction involves a substance reacting with oxygen. $4NH_3 + 5O_2\rightarrow 4NO + 6H_2O$ is ammonia reacting with oxygen.
