Question

what kind of reaction is this:
$2h_2o_2 \
ightarrow 2h_2o + o_2$

• synthesis
• single replacement
• combustion
• decomposition

question 6 1 pts
the reaction below is an example of?
$agno_3 + nacl \
ightarrow agcl + nano_3$

• single replacment
• combustion
• double replacment
• decomposition

Explanation:

First Question

A decomposition reaction is when a single compound breaks down into two or more simpler substances. In the reaction \(2H_2O_2
ightarrow2H_2O + O_2\), hydrogen peroxide (\(H_2O_2\)) breaks down into water (\(H_2O\)) and oxygen (\(O_2\)).

A double - replacement reaction occurs when the positive and negative ions of two ionic compounds exchange places. In the reaction \(AgNO_3+NaCl
ightarrow AgCl + NaNO_3\), the \(Ag^+\) from \(AgNO_3\) combines with \(Cl^-\) from \(NaCl\) and \(Na^+\) from \(NaCl\) combines with \(NO_3^-\) from \(AgNO_3\).

Answer:

Decomposition
