Does carbon monoxide bond to hemoglobin more effectively then oxygen does?

Yes - haemoglobin has a higher affinity for carbon monoxide than oxygen. This means that it will bind to carbon monoxide in preference.
The binding of carbon monoxide at one site of the haemoglobin increases the affinity for oxygen at the other 3 sites - which may cause problems as the oxygen is not released when it should be.
Yes, irreversible while with oxygen reversible
Yes, that's why you suffocate if you get stuck in a car with the exhaust coming in. The Carbon Monoxide sticks to your haemoglobin so the oxygen cannot.

Does carbon monoxide bind to hemoglobin or oxygen better?
Carbon monoxide bind easily to hemoglobin.
How does carbon monoxide affect oxygen?
Carbon monoxide reduces the oxygen saturation of hemoglobin at any given PaO2.
Which gases will replace oxygen in blood hemoglobin?
Carbon monoxide will replace, and displace, oxygen on hemoglobin. This is why carbon monoxide poisoning is so dangerous as the tissues slowly lose access to oxygen.
What two gases bind to hemoglobin?
Oxygen and carbon monoxide
Which gas binds to hemoglobin more strongly than oxygen?
Carbon monoxide. It has ten times higher binding efficiency to iron in the heme group than oxygen does
Does carbon monoxide helps oxygen get into the blood stream?
No. Quite the opposite: carbon monoxide binds to hemoglobin, which prevents the blood from carrying oxygen. This condition can be fatal.
In an unventilated space carbon monoxide from smoke or car exhaust builds up in the blood combining with hemoglobin to form?
When CO is not ventilated it binds to hemoglobin, which is the principal oxygen-carrying compound in blood; this produces a compound known as carboxyhemoglobin. The traditional belief is that carbon monoxide toxicity arises from the formation of carboxyhemoglobin, which decreases the oxygen-carrying capacity of the blood and inhibits the transport, delivery, and utilization of oxygen by the body. The affinity between hemoglobin and carbon monoxide is approximately 230 times stronger than the affinity between hemoglobin and oxygen so hemoglobin binds to carbon monoxide in preference to oxygen. ~ Wikipedia.
Which gas enters the bloodstream through the lungs and binds to hemoglobin and reduces the amount of oxygen that reaches the body's organs and tissues?
Carbon monoxide
What gas blocks oxygen from combing with hemoglobin in the lungs?
carbon monoxide (CO)
Which substance binds more tightly than oxygen to hemoglobin?
carbon monoxide
Which chemical in tobacco smoke binds to hemoglobin?
The chemical from tobacco smoke that binds with hemoglobin causing red blood cells to carry less oxygen is carbon monoxide.
What is the equation for carbon monoxide poisoning?
CO Carbon monoxide is combined with hemoglobin and carboxyhemoglobin is formed; this compound block the diffusion of oxygen in blood.
