Why is the oxidation state of carbon in carbon monoxide is 2 while in carbon dioxide is 4?
The oxidation state of carbon in carbon monoxide (CO) is +2 because it is bonded to one oxygen atom, which is more electronegative and pulls electrons away from carbon, resulting in a partial positive charge. In carbon dioxide (CO2), carbon is bonded to two oxygen atoms, each pulling electrons away, leading to a higher oxidation state of +4. Thus, the difference in the number of oxygen atoms and their electronegativity determines the varying oxidation states of carbon in these compounds.
How do substances pass through the stomata?
Substances pass through the stomata, which are small openings on the surface of leaves, through a process called transpiration. Water vapor exits the plant through the stomata, creating a negative pressure that pulls water and dissolved nutrients from the roots up through the plant's vascular system. This movement of water and nutrients is facilitated by a combination of cohesion, adhesion, and capillary action within the plant's xylem vessels. Additionally, gases such as carbon dioxide and oxygen can diffuse through the stomata to support photosynthesis and respiration processes in the plant.
How does water enter leaves?
Water enters the root cells by osmosis and enters into the xylem. The pressure of water entering the xylem creates osmotic pressure, pushing the column of water up through the stem. Water evaporating on the surface of the leaf cells pulls on other molecules and pulls the column of water up the plant and into the leaves.
How does hydrogen help the transport of water in plants?
Each water molecule pulls on other water molecules as water is transpired from the leaves of the plant. This allows free movement of water throughout the plant.
What effect does hyperventilation have on the concentration of co2 in the blood?
Hyperventilation leads to a decrease in carbon dioxide (CO2) concentration in the blood. This occurs because rapid breathing removes more CO2 than the body produces, causing respiratory alkalosis and potentially leading to symptoms such as dizziness, tingling, and muscle spasms.

What helps humans breathe?
The Respiratory System
How do mammals breathe in or breathe out?
A network of muscles above the stomach but under the ribcage, called the Diaphragm, acts as a bellows and applies pressure on the lungs. It pulls down to cause the lungs to fill with air and pushed up to expel carbon dioxide from the lungs.
Do fruit Mentos explode with Diet Coke?
Mentos look like their real smooth, but really they have lots of little small imperfections all over the surface. If you look at a glass of coke at any stage you can see the bubbles rising through it, if you put your finger into the coke you can see that bubbbles will form all over your finger. This is the carbon dioxide escaping from the coke. By putting a mentos in there all those little imperfections that are on the surface of it allow all the carbon dioxide to come out of solution, because there are so many little voids etc.. the mentos pulls a lot of carbon dioxide out fast and that's why the bottle of coke fizz's up.

What is the oxidation state of carbon in carbon monoxide?
The oxidation state of carbon in carbon monoxide (CO) is +2. In CO, carbon is more electronegative than oxygen and pulls the shared electrons towards itself, giving it a formal oxidation state of +2.
When the plant has enough waterwhat swells up and pulls open the stomata so the plant can breath?
The guard cells of the stomata swell to form the stomatal pore
What force pulls dust and gas together?
Gravity is the force that pulls dust and gas together in space. The gravitational attraction between particles causes them to clump together, eventually forming larger structures like stars and planets.
What is the evolution of Venus's?
God made the planet VenusFactCarbon dioxide, chlorine, flourine, sulferic acid, argon, helium, sulfur dioxide and many other chemicals made Venus.Evolution of Venus...compacting of the chemicals because of gravitational pulls.
What is the shrinking of plant cells called when water leaves so the cell membrane pulls away from the cell wall?
plasmolysis
How does sugar get from the water to a celery leaf?
Sugar in celery leaves primarily originates from photosynthesis, where plants convert sunlight, carbon dioxide, and water into glucose. Once produced in the leaves, this glucose is transported through the plant's vascular system, specifically the phloem, to various tissues, including roots and stems. While water is absorbed by the roots and transported through the xylem to the leaves, the sugar synthesized in the leaves does not come directly from the water; rather, it is created through the photosynthetic process using water and carbon dioxide.
