Question

What is heat of combustion?

David Collins · Accepted Answer

question number two simply asks you to define a term that was introduced in this section very important term called Heat of Combustion. Heat of Combustion refers to the Delta H of a chemical reaction. The Delta H of a chemical reaction is often called the change in an therapy, and this is what defines a chemical reaction as endo thermic or eggs a thermic. It is extra thermic. If heat is released during the process, and for all combustion reactions, heat is released. So the heat of combustion, then, is Thea Mount of Heat Energy that is released during a combustion reaction. Well, what is the combustion reaction? It&#x27;s a fuel reacting with oxygen producing carbon dioxide and water, and it&#x27;s heat of combustion. Although not specified in this section, heat of combustion is typically expressed in units of calories or jewels or killer jewels per a specific amount per mole of the fuel or per gram of the fuel

Emily Marty · Answer

there are many ways that energy is transferred to another substance. Examples are through electric, current and heat. He is one of the simplest ways that energy can be transferred between an object of higher temperature toe lower temperature.

Keshav Singh · Answer

Adelphia combustion is defined as the amount of heat released when one Kimmel or one kg a few burn completely at a specified temperature and pressure during the steady flow combustion process. And the reaction is the difference between the top me off the reactant any specified state, and then they&#x27;ll be of the products at the same state for a complete reaction.

Nicholas White · Answer

combustion reaction is general term that describes the interactions between a hydro carbon and oxygen primarily to form carbon dioxide and water. And this is a general term that includes the combustion, many different fossil fuels or larger hydrocarbons. And it&#x27;s primarily the increasing levels of atmosphere is carbon dioxide that were increasingly concerned about the scientific community. And right here on the left, I have a general formula for combustion reaction. Again, this is these include hydrocarbons on DH. These can include other elements to their king, the oxygen on these molecules, plus some number of most oxygen. And again it produces primarily carbon dioxide and water. However, Ah, and incomplete combustion of larger hydrocarbons will lead Teo other unseen, undesirable and often carcinogenic side products. So a specific example of combustion reaction we can talk about is nothing. So methane is the smallest hydrocarbon ch, for it is a gas on DH again, it will react with oxygen to make a Sewell and Theo too Well, so what we need to dio always with our ah equations that we write is balance these equations. So on the left side, we can see we have to. We have two things. There&#x27;s methane and auction right side. We have water and carbon dioxide. And the thing that sticks out to me in this reaction in terms of balancing is the oxygen. So because there&#x27;s only auction on one side will balance that last. So carbon happens to be im good thing. So we got one on both sides. Now, when we get to hydrogen, this is where we&#x27;re gonna have to do. It&#x27;s a balancing. We have four on the left to get four on the right. We need to have two of these. So now that will be for And what we have left is oxygen. So on the right, we have two coming from the CIA to we have to come from the water and then sew for so in order balance this. We need to make Tio oxygen&#x27;s there. Okay, so those are combustion reactions

Sisi Gao · Answer

this question is asking the definition to combust your reaction. So combustion reactions are characterized by the reaction off a substance with oxygen to form well, more oxygen containing compounds, which often including water. They&#x27;re important because the most because most of our society&#x27;s energy is derived from combustion reactions. For example, natural gas reacts with oxygen to form carbon dioxide on water.

Matthew Lueckheide · Answer

All right. Welcome to Chapter 10. Causes of change. Um, we&#x27;re starting off pretty easy. A lot of these initial questions or just definition questions. So thinking about heat Ah, you may be familiar with with talking about heat in terms of cooking, um or, um, temperature in the summertime or wintertime in your house or apartment? Um, right. But he is actually, in its simplest terms, is just a form of energy. Um, it&#x27;s a form of thermal energy. So, um, because it&#x27;s a thermal, um is a word that refers to heat, right, Um, and he because it is an energy, we could measure it in. Ah, unit for energy, which is the Jewell J O u L e s. The unit is a capital J. Um, and essentially, the whole thing about this chapter is that you&#x27;re gonna be learning and doing calculations that protect too. Excuse me. Never that pertain to the the transfer of heat. So he is going to be transferred heat as it pertains to also temperature. Right. Um, so hotter or larger temperatures t he is transferred to, um colder or lower temperatures, essentially until they&#x27;re at the same temperature. And we&#x27;re gonna do many more problems on this
