Question description

1 methane burns in oxygen to yield carbon dioxide and water the chemical formula for this reaction is CH4+2O2-->CO2+2H2O what is the product or what are the products od this reaction?

water and methane

carbon dioxide and water

oxygen and methane

carbon dioxide and methane

2 carbon and oxygen combine ro form carbon dioxide what is the reactant in this chemicl reaction?

oxygen only

carbon and oxygen

carbon only

carbon dioxide

3 what doe the law of conservation of mass say

the mass of the reactants is less than the mass of th products in a chemical reaction

the mass of the products in a chemical reaction is unrelated to the mass of the reactants

the mass of the products in a chemical reaction is equal to the mass of the reactants

the mass of the reactants is greater than the mass of the products in a chemical reaction

4 which of the following equations is balanced

P+O2-->P2O5

4P+5O2-->2P2O5

P+2O2-->PO2

4P+2O2-->2P4O5

5 what type of chemical reaction is 4Fe+3O2-->2Fe2O3

decomposition

single displacement

double displacement

synthesis

6 what is usually released in a combustion reaction

elemental carbon

energy

a carbon based fuel

elemental oxygen

7 hydrogen when combined with oxygen in a chemical reaction forms water this is an example of which type of chemical reaction

single displacement

double displacement

synthesis

decompostion

8 which of the following best describes why MnSO4--> MnO +SO3  is NOT a synthesis reaction

energy is not a product in this reaction

oxygen is not a reactant in this reaction

the reaction has more thsn one product

the equation is not balanced

9 if MnSO4-->MnO+SO3 is NOT a synthesis reaction then what type of reaction is it

combustion

single displacement

decomposition

double displacement

10 which of the following statements about decompostion reactions is true?

decompostion and single displacement reactions are the same thing 

decompostion reactions and esstentailly the opposite of synthesis reactions 

decompostion reactions are essentially the opposite of single displacement reactions

decompostion and combustion reactions are the same thing
