How many times larger in the number of hydrogen atoms than oxygen atoms in all carbohydrates?
2 times larger
What is the chemical equation for an imperfect perfect burn?
An imperfect burn of a hydrocarbon like methane can produce carbon monoxide (CO) instead of carbon dioxide (CO2), due to insufficient oxygen. The chemical equation for an imperfect burn of methane is CH4 + O2 → CO + H2O.
Percentage of carbon in human body?
Every human cells, and in fact all living organic matter, contains carbon. It is the basis for the life cycle of living things. Carbohydrates (containing carbon, hydrogen, and oxygen) provide the structural parts and the energy supply of living cells.
Why plant can take in the same molecule of carbon dioxide more than once?
Carbon dioxide is biologically recycled. Plants make sugar with it, by means of photosynthesis, and then animals may eat that plant or the part of the plant that contains the sugar, and they metabolize the sugar and produce carbon dioxide as a waste product, which gets exhaled into the air. Plants can then absorb that same carbon dioxide molecule from the air, and use it to make sugar again. There is no limit to the number of times that this can be repeated.
How many times per minute does the exchange of carbon dioxide for oxygen in the body normally occur?
The exchange of carbon dioxide for oxygen in the body normally occurs about 12-20 times per minute at rest during breathing. This allows for the uptake of oxygen by the lungs and the release of carbon dioxide as a waste product.
How many atoms are there in a sugar cube?
n = amount of mole
How many times larger is the number of hydrogen atoms than oxygen atoms in disaccharide?
the basic formula is C6H12O6, so there are twice as many number of hydrogen-to-oxygen atoms. This applies to carbon atoms as well when compared to hydrogen atoms.
What is evidence that supports the law of constant composition?
The mass ratio of carbon to oxygen in carbon dioxide is always 3:8 In a molecule of water, the mass of oxygen is always 8 times the mass of hydrogen
How many times larger is the number of hydrogen atoms then oxygen atoms in all carbohydrates?
The number of hydrogen atoms is typically twice the number of carbon atoms in carbohydrates, while the number of oxygen atoms is similar to the number of carbon atoms. Therefore, the number of hydrogen atoms is usually larger than the number of oxygen atoms in carbohydrates.
How percentage of oxygen is more in water than hydrogen?
This is true for mass-%. Oxygen is 16 times heavier than hydrogen, that outfigures the double elemental ratio for hydrogen to oxygen (2:1) by factor 8 times.
Which two elements make up three-fourths of the human body?
There is sixty percent water in your body. Water is made up of oxygen and hydrogen. There are double the number of hydrogen atoms or molecules as compared to oxygen in the water. But you have the mass of oxygen atom or molecule is 16 times more than that of hydrogen atom or the molecule. In case of water hydrogen to oxygen mass is one to eight, in proportion.
How are word equations written to describe chemical reactions?
Word equations use words to represent the reactants, products, and conditions of a chemical reaction. For example, the reaction between hydrogen and oxygen to form water can be written as "hydrogen + oxygen --> water." The arrow signifies the direction of the reaction and usually indicates the formation of the products from the reactants.
Which element is 16 times heavier that hydrogen?
Carbon
What is the 2 in H20 called?
Hydrogen times Oxygen
How many atoms are represented in the formula 6C6H12O6?
Multiply the coefficient in front of the formula times the subscript for each element. This gives 36 carbon atoms, 72 hydrogen atoms, and 36 oxygen atoms.
How many times larger in the number of hydrogen atoms than oxygen atoms in all carbohydrates?
2 times larger
