Answer:
The balanced reaction is this:
2 C₄H₁₀ (g) + 13 O₂(g) → 8 CO₂(g) + 10 H₂O (g)
Explanation:
Combustion is a chemical reaction whose reagents are oxygen, usually in excess and a hydrocarbon to generate carbon dioxide and water in the form of steam, as products.
Butane is considered as a reactant and it is a sort of alkane, in this case with 4 C (prefix but).
O₂ is needed for the complete combustion of butane.
Answer: 1) endothernic
2) Yes absorbed
Explanation:
Decomposition is a chemical reaction in which one reactant gives two or more than two products. All decomposition reactions are endothermic reactions as energy is absorbed to break the bonds.
Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and 
for the reaction comes out to be positive.
Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and for the reaction comes out to be negative.
Answer:
Explanation:
Carbon dioxide is a chemical compound that consists of two oxygen atoms and one carbon atom. … Carbon Dioxide (CO2) is a gas with a molecular structure composed of two oxygen atoms and one carbon atom. It is an important greenhouse gas because of its ability to absorb infrared wavelengths.
The answers to this problem is C
