How do you solve a reaction stoichiometry problem?
Almost all stoichiometric problems can be solved in just four simple steps:
- Balance the equation.
- Convert units of a given substance to moles.
- Using the mole ratio, calculate the moles of substance yielded by the reaction.
- Convert moles of wanted substance to desired units.
What is a stoichiometric formula?
Stoichiometry /ˌstɔɪkiˈɒmɪtri/ is the calculation of reactants and products in chemical reactions in chemistry. Because of the well known relationship of moles to atomic weights, the ratios that are arrived at by stoichiometry can be used to determine quantities by weight in a reaction described by a balanced equation.
How do I fix my car running rich?
How to Fix Car Running Rich
- Check Air Duct Flap. You will find a flap inside air duct which, acts as an open/ close valve.
- Inspect Vacuum Lines and Hose pipes. If you notice loose vacuum lines and leaking radiator hose pipe, your car will run rich.
- Clean MAF sensor.
- Replace the Faulty Oxygen Sensor.
- Change Spark Plugs.
What are the symptoms of a car running lean?
A lean running condition may manifest in driveability symptoms that have not (or not yet) triggered a DTC. Customer complaints may include symptoms such as decreased fuel economy, lack of power, hesitation on acceleration, backfiring through the intake, overheating, weird smells or other problems.
Can bad spark plugs make a car run lean?
Can bad spark plugs cause a lean condition? No. Lean condition is more air than fuel. Bad spark plugs usually results in a rich condition since the fuel is not being burned fully.
What does system too lean at idle mean?
The P2187 OBD-II fault code means the vehicle’s on-board computer has detected a lean fuel mixture at an idle in either Bank 1 or Bank 2 (the side of the engine with the corresponding number on the cylinder, if applicable). A lean fuel mixture means there is an excess of air and a shortage of fuel.
How do I fix my fuel system too lean?
What repairs can fix the P0171 code?
- Replacing the fuel pump.
- Replacing the fuel filter.
- Replacing the fuel pressure regulator.
- Replacing the powertrain control module.
- Replacing one or more injectors.
- Replacing one or more oxygen sensors.
- Replacing the mass air flow sensor.
- Repairing a vacuum leak.
Can a bad O2 sensor cause a car to run lean?
Yes the O2 sensor can cause the vehicle to run lean. What the O2 sensor does is read the amount of air entering the engine and sends that information to the computer, the computer reads this information and determines how much fuel the engine needs.
What does System Too Lean Bank 1 mean?
The OBDII trouble code P0171 – System Too Lean (Bank 1) means that the engine air-fuel mixture is too lean, or there is too much air and too little fuel. Driving a car with the code P0171 can cause more damage to the engine over time, as when the engine runs lean, the combustion temperature is higher.
How much does it cost to fix a system too lean Bank 1?
The average cost to replace the PCM is between $500 and $1,500.
What side of the engine is Bank 1?
Bank 1 and Bank 2 refer to different sides of the engine. Bank 1 is the side with cylinders 1, 3, 5, 7. Bank 2 is the side with cylinders 2, 4, 6, 8. The easiest way to discover the right cylinder bank is to check your car’s repair manual.
What is Bank 1 on an engine?
Bank 1 and bank 2 simply refer to either side of the engine. Most commonly, bank 1 houses the front most cylinder on the engine cylinder 1, and bank 2 is the opposite side of the engine.
