lime water (calcium hydroxide) turns milky when carbon dioxide is present
The reaction between carbon (in the form of graphite or carbon black) and sand (primarily composed of silicon dioxide, SiO₂) can be represented by the equation: [ \text{C} + \text{SiO}_2 \rightarrow \text{Si} + \text{CO}_2 ] In this reaction, carbon reduces silicon dioxide to silicon while producing carbon dioxide as a byproduct. This reaction is typically carried out at high temperatures.
When carbon dioxide is passed over hot coke, a chemical reaction occurs that produces carbon monoxide and carbon. This reaction is represented by the equation: ( \text{CO}_2 + \text{C} \rightarrow 2\text{CO} ). The carbon monoxide formed can be used as a reducing agent in various metallurgical processes.
The oxidation of NADH during the conversion of pyruvic acid to carbon dioxide occurs in the citric acid cycle (Krebs cycle). The reaction can be simplified as follows: [ \text{C}_3\text{H}_4\text{O}_3 , (\text{pyruvic acid}) + \text{NAD}^+ + \text{CoA} \rightarrow \text{C}_2\text{H}_3\text{O} + \text{CO}_2 + \text{NADH} + \text{H}^+ ] In this process, pyruvic acid is decarboxylated to produce acetyl-CoA, releasing carbon dioxide and reducing NAD+ to NADH.
The unbalanced formula equation for the combustion of propane (C₃H₈) with oxygen (O₂) producing carbon dioxide (CO₂) and water (H₂O) is: [ \text{C}_3\text{H}_8 + \text{O}_2 \rightarrow \text{CO}_2 + \text{H}_2\text{O} ] In this equation, one molecule of propane reacts with oxygen to produce carbon dioxide and water, but the coefficients are not yet balanced.
To calculate the number of moles of carbon dioxide (CO₂) in 44.009 grams, you can use the molar mass of CO₂, which is approximately 44.01 grams per mole. Using the formula: [ \text{moles} = \frac{\text{mass (g)}}{\text{molar mass (g/mol)}} ] we find: [ \text{moles} = \frac{44.009 , \text{g}}{44.01 , \text{g/mol}} \approx 1 , \text{mole} ] Thus, the bottle contains approximately 1 mole of carbon dioxide molecules.

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.

carbon dioxide
Carbon is an element, but not carbon dioxide. Carbon dioxide is a compound of carbon and oxygen.
Carbon dioxide is produced as a byproduct of cellular respiration in organisms, including humans and animals. During respiration, glucose is broken down in the presence of oxygen to produce energy, water, and carbon dioxide.
Carbon Dioxide
CO2 is the chemical formula of carbon dioxide.
All carbonated drinks, including Coca Cola, use carbon dioxide (CO2).
