Questions and answers

Which is more stable CO or CO2?

Which is more stable CO or CO2?

Answer: At room temperature, CO2 is more stable than carbon monoxide. The enthalpy of formation of carbon dioxide is more as that of carbon monoxide and hence carbon becomes more stable at higher temperature.

Which oxide of carbon is more stable?

Complete answer: Graphite is thermodynamically the most stable form of carbon. Its standard enthalpy of formation is thus taken as zero. Let us see why it is more stable than all the other given allotropes of carbon.

What is the best way to store carbon dioxide?

The most well-developed approach to storing CO2 is injecting it underground into naturally occurring, porous rock formations such as former natural gas or oil reservoirs, coal beds that can’t be mined, or saline aquifers.

What two processes keep CO2 stable?

Biology Chapter 5 Test

photosynthesis and respiration which 2 processes keeps the CO2 concentration stable
carbon dioxide plants depend on animals for the continuous supply of what
photosynthesis which process removes carbon dioxide from atmosphere
respiration which process adds carbon dioxide to atmosphere

How is CO2 stable?

Carbon dioxide (CO2) is a stable and relatively inert triatomic molecule that exists as a gas at ambient temperature and pressure. A CO2 molecule exhibits a linear structure in which the carbon is bonded to each oxygen atom via a sigma and pi bond forming two C=O. bonds.

Is carbon dioxide a stable compound?

carbon dioxide, chemical compound, CO2, a colorless, odorless, tasteless gas that is about one and one-half times as dense as air under ordinary conditions of temperature and pressure. It is a fairly stable compound but decomposes at very high temperatures into carbon and oxygen.

Why is carbon dioxide so stable?

Which of the following oxide is least stable?

Carbon dioxide is the least stable oxide.

Where is c02 stored?

Once the carbon dioxide has been transported, it is stored in porous geological formations that are typically located several kilometers under the earth’s surface, with pressure and temperatures such that carbon dioxide will be in the liquid or “supercritical phase.” Suitable storage sites include former gas and oil …

What is the storage form of carbon?

Carbon is stored on our planet in the following major sinks (1) as organic molecules in living and dead organisms found in the biosphere; (2) as the gas carbon dioxide in the atmosphere; (3) as organic matter in soils; (4) in the lithosphere as fossil fuels and sedimentary rock deposits such as limestone, dolomite and …

What is the greatest store of carbon?

What does CO2 react with?

Carbon dioxide reacts with water in a reversible reaction to form carbonic acid (H2CO3). The acid dissociation constant for carbonic acid Ka = 4.45 x 10-7 mol dm-3.
