What makes incomplete combustion more dangerous than complete combustion?
Incomplete combustion involves the generation of carbon monoxide in addition to carbon dioxide and water generated in complete combustion. Carbon monoxide is highly toxic. While carbon dioxide is produced by the body itself and can only kill if at a very high concentration (7% to 10% of air by volume) or by depriving the victim of oxygen for prolonged periods of time, carbon monoxide is not a physiological gas and can kill at low concentrations (0.32% of air by volume) and in a relatively short amount of time (less than 30 minutes). The toxicity of carbon monoxide is believed to be involved in compromising the ability of hemoglobin and myoglobin to transfer and store oxygen and disabling cellular respiration through blocking cytochrome oxidase.
How does water gas compare to methane in terms of thermal energy produced?
Water gas (a mixture of carbon monoxide and hydrogen produced by passing steam over hot carbon) has a lower thermal energy content compared to methane. Methane produces more heat energy per unit volume when burned due to its higher carbon-hydrogen ratio and higher calorific value.
What volume of carbon dioxide gas is produced after the complete combustion of 1 L of methane gas?
When methane is completely combusted, 1 mole of methane yields 1 mole of carbon dioxide. So, if 1 liter of methane gas is burned, it would produce 1 liter of carbon dioxide gas.
Which must be the same when comparing 1 mol of oxygen gas O2 with 1 mol of carbon monoxide gas CO?
When comparing 1 mol of oxygen gas (O₂) with 1 mol of carbon monoxide gas (CO), the number of molecules must be the same, as both contain 1 mol. Additionally, both gases will have the same volume under standard temperature and pressure conditions, which is approximately 22.4 liters. However, their molar masses and chemical properties differ significantly.
What is the volume that 35.2 g of carbon tetrachloride will occupy if it has a density of 1.00gml?
The volume of carbon tetrachloride can be calculated using the formula: Volume = Mass / Density. So, the volume of 35.2 g of carbon tetrachloride with a density of 1.00 g/ml would be 35.2 ml.

What volume of carbon monoxide at STP is needed to produce 541 mL of carbon dioxide?
Using the ideal gas law - the volume of a gas is independent of it composition and is determined solely by the equation PV=nRT. As one mole of CO would produce one mole of CO2 it would take 541 mL of CO to produce 541 mL of CO2.
How many liters of oxygen are needed to burn 10 liters of carbon monoxide?
Because carbon monoxide has half the number of oxygen molecules than carbon dioxide, doubling the volume of carbon monoxide gives the required volume of oxygen needed to burn it. Thus, 20 liters of oxygen are needed to burn 10 liters of carbon monoxide.
When two gases of a chemical reaction are both at the same temperature and pressure and they have the same molar volume what is their stoichiometric ratio in the chemical equation describing the reac?
If the gases have the same molar volume, the stoichiometric ratio would be one to one. Molar volume is the volume occupied by one mole of a substance. This indicates that there is a 1:1 molar ratio of each gas.
Is carbon monoxide compressible?
Yes, carbon monoxide is compressible. Like all gases, it can be easily compressed into a smaller volume by increasing pressure. This is due to the fact that gases have more empty space between their particles compared to solids and liquids.
Which type of stoichiometric calculation does not require the use of molar mass?
Volume-volume stoichiometric calculations do not require the use of molar mass, as they involve the relationship between volumes of reactants and products in a chemical reaction. This type of calculation is commonly used when dealing with gases at standard temperature and pressure.
How many liters of carbon monoxide gas are formed if 0.75 moles of carbon react completely with silicon dioxide?
The balanced chemical equation for the reaction between carbon and silicon dioxide does not produce carbon monoxide gas. Rather, it forms silicon carbide (SiC) and carbon dioxide (CO2). To calculate the volume of carbon monoxide gas formed, you would need a different chemical reaction that specifically produces carbon monoxide from the reaction of carbon with a different compound.
Flue gas analysis by Orsat apparatus?
The Orsat apparatus is used to analyze the composition of flue gases, typically measuring oxygen, carbon dioxide, and carbon monoxide levels. The apparatus involves passing a known volume of flue gas through different chemical solutions to absorb specific gases, allowing for quantification of each component. This analysis helps assess combustion efficiency and environmental impact of fuel-burning processes.
What is the meaning of percent of carbon dioxide in auto emissions?
Auto emits carbon monoxide(CO), carbon dioxide(CO2) and some other gases and particles which pollute the environment. the amount of CO2 compared to total amount of emission in percentage is called as percent of carbon dioxide in auto emissions. %CO2=(Volume of CO2 emitted/Total volume of emission)*100
What is the volume of a container that holds 25.0 g of carbon monoxide gas at STP?
The volume of a container that holds 25.0 g of carbon monoxide gas at STP (standard temperature and pressure) can be calculated using the ideal gas law equation (V = nRT/P), where n is the number of moles of the gas, R is the ideal gas constant, T is the temperature, and P is the pressure at STP. At STP, T = 273 K and P = 1 atm. The number of moles (n) can be calculated using the molar mass of carbon monoxide (28.01 g/mol). Substituting these values into the ideal gas law equation will give you the volume of the container.
How is fuel air ratio measured?
The fuel-air ratio is measured by comparing the mass or volume of fuel to the mass or volume of air present in a combustion process. This is typically expressed as a ratio, such as 14.7:1 for stoichiometric combustion of gasoline, indicating the ideal proportion for complete combustion. Instruments like mass flow meters, lambda sensors, or fuel flow sensors are used to obtain accurate measurements of both fuel and air. The ratio can also be calculated using engine management systems that monitor engine parameters in real-time.
What are the total air volume supply requirements for an atmospheric burner?
The total air volume supply requirements for an atmospheric burner depend on factors such as the burner size, fuel type, and combustion efficiency. Typically, air volume is calculated based on the stoichiometric air-to-fuel ratio required for complete combustion. It is important to ensure that the correct amount of air is supplied to achieve optimal combustion and prevent issues such as inefficient burning or production of harmful emissions.
