What are things used over and over again during photosynthesis and respiration?
During photosynthesis and respiration, key molecules such as carbon dioxide, water, and oxygen are reused in the processes. In photosynthesis, plants convert carbon dioxide and water into glucose and oxygen using sunlight. Conversely, in respiration, organisms use glucose and oxygen to produce energy, releasing carbon dioxide and water as byproducts. This cyclical exchange of these substances is essential for maintaining life on Earth.
How do oceans decrease the amount of atmospheric carbon dioxide?
Oceans absorb carbon dioxide from the atmosphere through a process called carbon sequestration. Marine plants, such as phytoplankton, also capture carbon dioxide through photosynthesis. Additionally, when carbon dioxide dissolves in ocean water, it forms carbonic acid, which then reacts with minerals in the water to create bicarbonate ions, effectively storing the carbon.
What role does carbon dioxide play when breaking down limestone?
Carbon dioxide reacts with water to form carbonic acid, which can dissolve limestone over time. This process is known as carbonation and results in the breakdown of limestone through chemical weathering.
How did the oceans reduce the carbon dioxide levels?
The oceans help to keep the carbon dioxide level in the atmosphere low by dissolving a large portion of CO2 from the atmosphere. Unfortunately, the increased CO2 in the atmosphere is causing the oceans to become more acidic.
Why does carbon dioxide have a higher bond order than water?
Carbon dioxide has a higher bond order compared to water. This is due to the stronger bond that forms between carbon and oxygen, which is greater than the bond between hydrogen and oxygen.
How is the volume of the carbon dioxide collected over water measured per Dalton's Law of Partial Pressures in Purdue edu experiment called Collection of Gas Over Water?
In the Purdue University experiment "Collection of Gas Over Water," the volume of carbon dioxide collected over water is measured by displacing the water and collecting the gas in a calibrated tube. Dalton's Law of Partial Pressures states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of each individual gas. Since the experiment involves collecting the gas over water, the partial pressure of water vapor needs to be accounted for when measuring the volume of carbon dioxide.
Why is carbon dioxide collected by downwards delivery?
Carbon dioxide (CO2) is collected by downwards delivery because it is heavier than air. Almost all of our atmosphere is nitrogen (molecular mass = 28) and oxygen (molecular mass = 32), but CO2 has a molecular mass of 40.
Which gas may be collected over water?
No, only those that do not dissolve in water, or they will dissolve in the water rather than bubble through it to be collected. Examples of gases that can be collected over water include:- Hydrogen, nitrogen, oxygen (only slightly soluble), methane, carbon monoxide. Examples of gases that can just be collected over water (quie soluble - so much will be dissolved in the water as well):- Nitrogen dioxide, carbon dioxide, chlorine Examples of gases that are too soluble to be collected over water:- hydrogen chloride, ammonia (which is the most soluble of all gases) Both of these gases are collected by displacement of air - hydrogen chloride by the gas jar being held as in a glass - with the base on the table - because it is heavier than air (chlorine and carbod dioxide can be collected like this too) and and ammonia by the gas jar being held upside down to trap the ammonia (as it is lighter than air).
How does the fish get its oxygen and how does carbon dioxide is removed?
The water that the fish swims in passes over the gills - these work like our own lungs - taking in oxygen, and expelling carbon dioxide. This is why you need to change the water in the tank on a regular basis - because the level of carbon dioxide increases daily.
Carbon dioxide and water vapor act like a blanket over the earth?
greenhouse effect
Will fizzy water bubble over like soda?
Fizzy water is soda. They are both carbonated water which is water with carbon dioxide dissolved in it.
How carbon dioxide fluctuate if monitored over coniferous forest stand?
How something reacts to Carbon Dioxide will depend on the amount of energy available, and the temperature of the Carbon Dioxide. Carbon Dioxide fluctuates more when it is over a coniferous forest stand.
Does the level of carbon dioxide rise or fall in a room over time?
The level of carbon dioxide typically rises in a room over time as people exhale carbon dioxide as they breathe.
How is the cell's use of carbon dioxide and water similar to people's recycling of paper and plastic bottles?
Cells give out carbon dioxide like people give out paper and plastic bottles. They re-use them over and over again.
What processes removes carbon dioxide from the air or water?
Photosynthesis in plants and algae is a natural process that removes carbon dioxide from the air. In water, carbon dioxide can be absorbed by algae and other aquatic plants through a process called aquatic photosynthesis. Additionally, chemical weathering of rocks can also help remove carbon dioxide from the atmosphere over long periods of time.
Aerobic respiration has the production of what over anaerobic respiration?
Aerobic respiration forms carbon dioxide and water vapour producing glucose while anaerobic respiration forms carbon dioxide and lactic acid.
Why Is Normal Rain Water Slightly Acidic?
Normal rain water is slightly acidic due to dissolved carbonic acid. Rainwater absorbs carbon dioxide from the air, leading to its slight acidity. When additional carbon dioxide or sulphur dioxide is released into the air, it is absorbed into clouds and makes rain more acidic.
