Answer:

I always enjoy a good meal, so I'd say baking is my favorite household chemical reaction.

Explanation:

You are creating an endothermic reaction whenever you bake as the sugars and other molecules are broken apart, fused, and rearranged to make a delicious cake!

Answer:

Sodium Hypochlorite 

Explanation:

Sodium Hypochlorite – Sodium hypochlorite (a.k.a. bleach) is one of the most commonly used chemicals in the world. A solution of sodium hypochlorite is frequently used as a disinfectant and as a bleaching agent. Often it is simply called “bleach”, though other chemicals are sometimes given that name as well.

nikklg [1K]

Answer:

H_{comb}=-4406kJ/mol

Explanation:

Hello,

In this case, the enthalpy of combustion is understood as the energy released when one mole of fuel, in this case octene, is burned in the presence of oxygen and is computed with the enthalpies of formation of the fuel, carbon dioxide and water as shown below (oxygen is circumvented as it is a pure element):

H_{comb}=8*\Delta _fH_{CO_2}+5\Delta _fH_{H_2O}-\Delta _fH_{C_8H_{10}}

Thus, since we already know the enthalpy of combustion of the fuel, for carbon and water we have -393.5 and -241.8 kJ/mol respectively, thereby, the enthalpy of combustion turns out:

H_{comb}=8*(-393.5kJ/mol)+5(-241.8kJ/mol)-49.0kJ/mol\\\\H_{comb}=-4406kJ/mol

Best regards.

What are the chemical properties of oxygen?
wlad13 [49]
Hmm.... Oxygen support combustion. Other than that, rusting occur when oxygen is combined with metal. When iron rusts, it combines with oxygen. Hope it helps.
