WHY does calcium belong in group 2?
The periodic table is organized in order of increasing number of electrons. Column-wise, the elements are divided into groups. With the exception of the transition metals in the middle of the period table, all the other groups have the same number of valence electrons within each groups.
Calcium has 2 valence electrons, meaning that there are two electrons in its outermost shell of electrons. All group 2 elements have two valence electrons. So calcium belongs in group 2. It is also there because of how the table is arranged in the order of increasing atomic number
What is the chemical equation for carbon dioxide plus oxygen equals methane?
The chemical equation for the reaction between carbon dioxide and oxygen to form methane is not possible as it involves a reduction process, which is not spontaneous under normal conditions. Methane is usually produced through other processes, such as the reaction between hydrogen and carbon dioxide known as Sabatier reaction.
Does an oil burning furnace release carbon dioxide fumes?
Yes, oil burning furnaces release carbon dioxide as a byproduct of combustion. It is important to ensure proper ventilation to prevent build-up of carbon monoxide, a potentially harmful gas produced by incomplete combustion. Regular maintenance and proper installation of the furnace are crucial for safety.
What is it called when carbon dioxide is released?
The release of carbon dioxide is called carbon dioxide emissions. This occurs when carbon dioxide gas is released into the atmosphere from various sources such as burning fossil fuels, deforestation, and industrial processes.
Yes, chacma baboons are omnivores. Their diet consists of a variety of foods including fruits, seeds, insects, small mammals, and occasionally other animals like birds or reptiles. They are opportunistic feeders and adapt their diet based on what is available in their environment.
What organisms return nitrogen back into the air?
The organisms that are involved in the movement of nitrogen between the air and soil and back to the air are plants and bacteria. When plants decompose they release nitrogen and bacteria fixes nitrogen back into the air.
When animals eat plants they use Carbon Dioxide to?
In the process of photosynthesis,plants make starch and oxygen not carbon dioxide.
After eating plant they create carbon dioxide as waste product when releasing food energy into cellular energy.So they just excrete CO2 the waste product of respiration.

What two types of stars that can form from nebula?
Two types of stars that can form from nebula are main sequence stars, like our Sun, and giant stars, which are larger and brighter than main sequence stars. Main sequence stars fuse hydrogen into helium in their cores, while giant stars have expanded and evolved from the main sequence phase.
When carbon dioxide reacts with oxygen what does it make?
If this reaction is done in the presence of O3 instead of O2, it makes highly unstable CO3 .
Added:
Its most probable molecular structure (lifetime less than 1 minute) is O=CO2 of which the CO2-part is triangular bonded, like ozone.
Carbon trioxide can be made by blowing ozone at dry ice (solid CO2).
What is the monkey with a rainbow butt called?
The monkey that is characterized by having a rainbow behind, as well as a colorful snout, is called the mandrill. This primate is closely related to baboons and is most commonly found on the African continent.
They do not belong to the same species. This is recognizable because in scientific names, the genus is first listed with a capital first letter (in this case, Papio). Next, the species name is listed uncapitalized (in this case, annubis and cynocephalus). It's written as "Genus species".
Do mitochondria release carbon dioxide?
Mitochondria do not release carbon dioxide. Instead, they consume oxygen and produce carbon dioxide as a waste product during cellular respiration. Carbon dioxide is then released into the bloodstream and exhaled by the lungs.
Where do the oxygen atoms in the carbon dioxide come from?
When Carbon reacts with Oxygen then the Carbon will react with the Oxygen and produce Carbon Dioxide
Where C is Carbon
Where O is Oxygen
Where CO2 is Carbon Dioxide
Sorry, but in a chemical equation, you should never put an equals sign '=', because you will lose marks, or not get any marks at all, if you wrote it in an Exam/Test
Here is how it works:
C + O = CO2
Where can i find a diagram of How does burning coal make carbon dioxide?
You can find diagrams illustrating the process of burning coal and producing carbon dioxide in science textbooks, online educational resources, or websites dedicated to climate change and environmental science. These diagrams typically show the combustion of coal releasing carbon dioxide as a byproduct, contributing to the greenhouse effect and global warming.
Why are carbon dioxide detectors used in border control?
they were used in border control because they were trying to stop illegal immigrints going from country to country;so the detectors monitor the level of co2 in the lorry and if it is over a certain number they searched the lorry

Why is carbon dioxide released from dead roots?
For a plant to live, it breathes in carbon dioxide. When a plant dies it still has to go somewhere if it isn't used, because the plant will start to decompose, so the carbon dioxide is released
What is the term for the land water climate plants and animals of a particular place?
The land, water, climate, plants, and animals of an area is referred to as an environment. You can use the word habitat to refer to the place where an animal or plant lives.
What biome that has the richest source of life In terms of both plants and animals?
Tropical rainforests are considered the biome with the richest source of life in terms of both plants and animals. They have high levels of biodiversity and support a wide variety of species due to their warm and wet conditions.
What volume of air that contains 450 mL of oxygen?
Oxygen comprises 20.946% of air...
therefore, the amount of air that contains 450mL of oxygen is:
(450mL) / (20.946%) = (450mL) / (0.20946) = 2148mL
Paying attention to significant figures (3) the final answer is 2.15 L of air.
****P.S.
Some teachers simplify the composition of air to contain only 20% oxygen.
If this is the case your answer becomes 2.25L of air.
.000380 is 380 millionths, ppm is to millionths what % is to hundredths. If you now move the decimal two places to the right to conver to a percentage, then 380 ppm is approximately .04%, and thus, CO2 makes up .04% of the air (which is what I assume this question is refering to)
Which cellular organelle is called the cellular power plant?
Mitochondira. This is the site of Aerobic respiration which typically yields the greatest amount of ATP.
Is the process of evaporating water from seawater a physical property?
No, the process of evaporating water from seawater is a physical change, not a physical property. Physical properties are characteristics of a substance that can be observed without changing the substance itself, whereas physical changes involve a change in the state or appearance of a substance without altering its chemical composition.
What two structures does water and minerals pass through to get to xylem?
Water and minerals pass through the root epidermis and root cortex cells to reach the xylem in plant roots. The root epidermis is the outermost layer of cells in the root, and the root cortex is a region of parenchyma cells between the epidermis and the vascular tissue (xylem and phloem).
Why are plants and animals losing their habitat in china?
Plants and animals are losing their habitat in China due to urbanization, deforestation, and pollution. Rapid industrialization and infrastructure development have encroached on natural habitats, leading to habitat loss and fragmentation. Additionally, activities like logging, agriculture expansion, and mining have further degraded the ecosystem, impacting a variety of species.
How is movement of oxygen similar and different from carbon dioxide?
Once oxygen has entered the red blood cells it begins its journey inside the body. It starts by moving through the capillaries in the lungs. Capillaries are just one of the kinds of blood vessels found in the body (The other two are Arteries and Veins). They make a network of fine tubes in organs which provide a very large surface area between the blood and the tissue in the organs. This surface area allows a large amount of substances, such as oxygen and glucose, to pass between the blood and the tissues in a short amount of time. When the blood moves away from the lungs, it travels along a larger blood vessel called the pulmonary vein. The oxygenated blood is transported to the heart in the pulmonary bein, and is then circulated around the body.
While, Carbon dioxide is a product of aerobic respiration. It leaves the cell where it is produced and passes through the walls of the cappillaries. It does not enter the red blood cells but stays in the plasma. It travels along veins which take it back to the right side of the heart. From here it enters the pulmmonary artery and travels to the lungs. It escapes through the capillary walls into the air in the alveoli.
