SO2 sensors have a cross sensitivity of approximately 150% to acetylene gas meaning if there are 45ppm acetylene gas in the air then your SO2 monitor will read approx 60ppm....one way to tell them apart is to have a second monitor to like a multi-gas or four-gas monitor or something that measures LEL's (lower explosive limit) values of flammable gases....If your showing 0 LEL's while getting a value for SO2 .... than it IS SO2 and NOT Acetylene. Where i work we have constant SO2 leak issues and the company i work for is always trying to blame it on acetylene to prevent WCB cases for low exposures...so I always bring a LEL measuring device with me to do SO2 gas sweeps and to eliminate the possibility of acetylene.....Also be aware that CO (Carbon Monoxide) will have a similar effect on H2S monitors....Hope this helps and be safe out there!

Sulfur dioxide Lewis structure?
The Lewis structure of sulfur dioxide has two double bonds between the sulfur and oxygen atoms. The S in the center has two double dashes, each connected to an O. The S then has one set of double dots and each O has two sets of double dots.
What is the chemical formula for sulfur dioxide with water vapor?
This is not one formula, but a complete set of the chemical reaction equations:SO2 + H2O [H2SO3] HSO3− + H+ (Sulfurous acid)Ka = 1.54×10−2; pKa = 1.81.
How do you separate sulfur and sand and iron fillings?
you can easily remove iron with magnet. then if you do not care about the sulfur you can set it on fire, and what is left will be pure sand. If you do care about sulfur i don't think i can help you.
How many moles of atoms are there in 48.096 grams of sulfur?
Full formal set up. 48.096 grams sulfur (1 mole S/32.07 grams)(6.022 X 1023/1 mole S)(1 mole S atoms/6.022 X 1023) = 1.4997 moles of sulfur atoms ---------------------------------------
Which substance rusts a nail faster?
Faster than what? Iron rusts when it is in the presence of water and oxygen. If you add salt to the water, it will rust more quickly than it does in pure water, which is why piers in the sea are inevitably rusty. The salt helps to set up an electro-chemical reaction that speed up the process by stripping off the coating of iron oxide as it forms on the surface of the metal. Sulfur dioxide and carbon dioxide dissolved in the water will also accelerate rusting.

How many o2 sensors are there on a 2001 V6 mustang?
There are four 02 sensors. Two in the Y pipe just before the first set of cats. Then a second set of sensors just before the last set of cats.

Why are sensors helpful?
Why are sensors helpful? That's my question.Well! Sensors help detect. If you have set a alarm light to get on when someone opens your pencil case that's sensor.
What is the three dimensional shape for acetylene?
A set of atoms in a straight line - with the two hydrogens on the outside and the two carbons in the middle.
How many sets of lone pairs are around sulfur in SF4?
One set of lone pairs is around sulfur in SF4.
How a weight sensors works?
Weight sensors work in a very simple way. Weight sensors can detect how much weight is being set on top of them much like a scale.

How many tire sensors can the 4runner support?
The Toyota can support for tire sensors. There is a tire sensor on each tire. The system is not set up to support anymore than four sensors.
How do you use a dip switch for a receiver receiving RF Signals from a set of three wireless sensors?
Answer: If your receiver have three decoders build in you can set the code differently, if it only have one decoder you set the dip switches on the sensors the same as the receiver, but then the receiver won't be able to identify the sensors, it won't be able to tell what sensor send the signal. This problem can be solved by using a micro processor system like the Multi Zone from Micro Developments that can identify 65535 different sensors and there is no dip switches to set each sensors code and ID is pre programmed on the sensor
What are the advantages and disadvantages of a sensors?
The advantages of light sensors is that they are really good security systems. The disadvantage of them is that they're really easy to set off.
Why must acetylene cylinders be stored upright?
Because the acetylene is stored dissolved in acetone. You don't want to get any liquid acetone up into the valve area where it can get into the regulator, as it can damage the regulator. If the tank does go on its side, be sure to set it upright and let it be for awhile before putting it in use.
