What type of reaction is represented by the following chemical equation?
ch4 + 2o2 ➡ co2 + 2h2o + heat/light
double replacement
single replacement
combustion
decomposition

combustion reaction.  

Explanation:

Th given chemical equation is a combustion reaction.  

CH₄ or methane is a hydrocarbon. When a hydrocarbon reacts with oxygen it forms carbon dioxide and water.  

All other options are incorrect.

In a single replacement reaction one element replaces another element in a compound.  

Zn + H₂SO₄ = ZnSO₄ + H₂

In a double replacement reaction the cations of the reactants combines with a different anion of the reactant to form new products.

AgNO₃ + NaCl = AgCl + NaNO₃

In a decomposition reaction a complex molecule is broken down into simple molecules.  

H₂O₂ = 2H₂O + O₂

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
