The question makes no sense as it is stated. There is a C=O bond, which is called a carbonyl group. It is written as shown, generally not as O=C. The C is carbon, which has four bonds connected to it. In this abbreviated form of this group, only two of its bonds are being shown. The O is oxygen, which has two bonds connected to it.

    Another thing to keep in mind, too, is that every element, for example, oxygen or carbon, is unique and is distinguishable from any other. Each element has a different atomic number, which corresponds to the number of protons in its nucleus. Carbon has an atomic number of 6, and oxygen has an atomic number of 8. So, you see, C can never equal O, nor can O every = C. Carbon and oxygen have quite different physical and chemical properties: for example, oxygen is a gas, and carbon is a solid. Carbon has a valence of 4 (that is, 4 electrons in its outermost energy level, and oxygen has a valence of 6 (i.e., 6 electrons in its outermost energy level). The number of electrons in an element's outermost or "valence" energy level determines the element's chemical reactivity and how many bonds it can form wtih other elements. So, no, C is never = to O, nor vice-versa.

Write down the hypothesis for this investigation of cellular respiration in a population of yeast material and equipment

Cellular Respiration in Yeast Video Lesson Transcript Study com

A hypothesis is a testable assertion rather than a question.

It is tricky to narrow the assertion to what is testable.

Are any of the following testable?

Fermentation by yeast occurs without oxygen.
Cellular respiration in yeast converts oxygen into carbon dioxide.
Cellular respiration in yeast converts oxygen into carbon dioxide and glucose.

Classify the following as elements or compounds 1.1 calcium carbonate 1. 2 neon

Calcium carbonate is a compound consisting of at least calcium and carbon, as the name implies. (The word carbonate also implies oxygen.)

Neon is an element.

My 1992 Pontiac Firebird stalls in idle, i recently had the cooling system repaired an the whole top of the engin was taken apart and cleand. I was told that some time the car has to reset its self for...

Cabon deposits in the throttle bore and on the throttle plate will limit airflow at idle and make a reset difficult. The throttle bore must be clean first. Carbon deposits on the idle control motor can impede this process also, but they do not take kindly to a liberal cleaning. I would recommend a new iac motor unless it has already been replaced.

What doest nicotine,tar and carbon monoxide do the lungs?

Nicotine is a stimulant, and in quantity, a poison. It may, or may not be, a carcinogen - studies vary.

Tar sticks to the lung's tissues and gums up the works, filling in the small sacs where gas exchange occurs. It may, or may not be, a carcinogen - studies vary.

Carbon monoxide displaces oxygen, binding well with hemoglobin, causing low oxygen blood levels, and in sufficient quantities, death due to oxygen deprivation.

Lastnight our monitor 441 heater went out. Our kerosene tank is full. We turned it back on, the ignighter will ignite and it will run for a little while then it will kick off again. Hardware store says it...

It could be carbon buildup, or it could be the oxygen depletion sensor that turns the unit off for your safety if the oxygen levels in the dwelling drop too low.

Try placing the unit hear a window with the window cracked open. Fire it up and see if it behaves differently. Fossil fuel space heaters can be dangerous in very cold weather because they consume large amounts of oxygen and can cause carbon monoxide poisoning - be careful.

A window should always be kept cracked in the are where the heater is operated.

The noise sounds like pistons or valves rattling when I have been driving the car a while. It seems like it does it more if I cut the car off and restart a lot, driving up hill, or accelerating.

You need to have the top engine cleaned, it has carboned up and has made the computer not to be able to adjust timing, with the cabon buildup it causes high compressin so the knock sensor and spark advance will not work.

2002 PCED OBDII-Villager SECTION 1: Description and Operation Catalyst and Exhaust System Overview The catalytic converter and exhaust system work together to control the release of harmful engine exhaust emissions into the atmosphere. The engine exhaust gas consists mainly of nitrogen, carbon dioxide and water vapor. However, it also contains carbon monoxide, oxides of nitrogen, hydrogen, and various unburned hydrocarbons. Carbon monoxide, oxides of nitrogen, and hydrocarbons are major air pollutants, and emission into the atmosphere must be controlled.
The exhaust system consists of an exhaust manifold combined with a pre-catalytic converter, upstream heated oxygen sensor (HO2S11), (located just in front of the pre-catalytic converter), three way catalytic converter (TWC), downstream heated oxygen sensor (HO2S12) (located in front of the TWC), a muffler and an exhaust tailpipe.
Heated Oxygen Sensors The Villager is equipped with both upstream and downstream heated oxygen sensors (HO2S) (Figure 1). The upstream heated oxygen sensor (HO2S11) is used to control engine fuel flow. The sensor detects the concentration of oxygen in the exhaust gas and sends a signal to the powertrain control module (PCM). In a rich condition, the HO2S will output a voltage of 0.6 volts or greater, and in a lean condition a voltage of 0.4 volts or less will be output.
The downstream heated oxygen sensor (HO2S12) is used primarily for monitoring the efficiency of the catalytic converter system. The HO2S12 works in a similar way to the HO2S11 but only indicates to the PCM that the catalyst is functioning properly. In the event that the HO2S11 fails, fuel control will be switched over to the HO2S12 and the malfunction indicator lamp (MIL) will be illuminated. This allows the vehicle to operate with fewer emissions, even with a sensor failure.
