carbon dioxide
carbon dioxide + water + heat
Carbon dioxide and water vapor belong in the blank space of the chemical equation for the burning of fossil fuels, as the reaction involves the combustion of hydrocarbons in fossil fuels in the presence of oxygen to produce carbon dioxide and water vapor, along with heat energy.
The answer that belongs in the blank space is "oxygen." The chemical equation for the burning of fossil fuels is typically written as: Fossil fuel + oxygen → carbon dioxide + water + heat.
The blank space should be filled with "oxygen." The complete chemical equation for the burning of fossil fuels is fossil fuel + oxygen + carbon dioxide + water + heat.
The general equation for the combustion of fossil fuels is: Fossil Fuel + O2 → CO2 + H2O + heat This equation represents the process where fossil fuels react with oxygen to produce carbon dioxide, water, and heat energy.
Fossil fuel + Oxygen gas > Carbon dioxide + water + heat (apex)
The chemical equation for the burning of fossil fuels can be represented by the general formula: ( \text{hydrocarbon (fuel)} + \text{oxygen} \rightarrow \text{carbon dioxide} + \text{water} + \text{heat} ). This represents the combustion reaction where hydrocarbons in fossil fuels react with oxygen to produce carbon dioxide, water, and heat energy.
Fossil fuels are hydrocarbons, so the main processes are: 1. carbon (fuel) + oxygen (air) produced carbon dioxide and heat 2. hydrogen (fuel) + oxygen (air) produces water (usually steam) and heat. In a typical fuel-burning process, 1 kg of fuel burns with 3.5 kg of oxygen to produce 3.1 kg of carbon dioxide and 1.4 kg of water. This is inescapable because the heat energy is released by the formation of the carbon-oxygen and hydrogen-oxygen chemical bonds.
The products of burning fossil fuels with oxygen gas are carbon dioxide (CO2) and water vapor (H2O). This combustion process releases energy that is commonly used in various human activities.
The heat is produced by the formation of chemical bonds between carbon and oxygen, and between hydrogen and oxygen. So CO2 and water are the necessary products when fossil fuel is burned, without which there would be no heat.
Carbon dioxide (CO2) belongs in the blank space of the chemical equation, as when fossil fuels burn, they produce carbon dioxide along with water and release heat as a byproduct. The balanced equation is typically represented as Fossil fuel + O2 + H2O + heat -> CO2 + H2O.
The fuel reacts with the oxygen to produce carbon dioxide and water, which appears as steam and is usually invisible. The reaction also produces heat, from the formation of carbon-oxygen bonds and hydrogen-oxygen bonds. A typical reaction is octane, for which 1 kg of fuel reacts with 3.51 kg of oxygen to produce 3.09 kg of carbon dioxide and 1.42 kg of water.
