What are four main elements from which protein is made?
All proteins contain carbon, hydrogen, oxygen and nitrogen. Most of them also contain sulfur, which is found in the standard amino acid residues cysteine and methionine (any given protein might not contain either of these, though it would be unusual).
What element is contained in proteins?
That answer would be carbon Sources: Biology teacher.
Which to atoms are the most common in the earth crust?
Hydrogen, Carbon, Oxygen, and Silica are the most common elements found in the Earth.
How would you test carbon dioxide to show that it was hydrogen?
Carbon dioxide form a milky suspension of calcium carbonate in calcium hydroxide; hydrogen doesn't react. But hydrogen react with oxygen when a flame exist.
What two atoms must organic molecules have in them?
If I absolutely had to answer with two atoms, I'd say carbon and hydrogen. This is because carbon is the absolutely indispensible atom that is the absolute basis of all organic molecules, forms they're backbones, and it is carbon's ability to make multible chemical bonds that allows for complex molecular structures. Secondly, hydrogen because any time a carbon molecule has a free chemical bond (not bound to another carbon or some other atom), it bonds to hydrogen. Hydrocarbons are entirely carbon and hydrogen. I must say however that for some organic molecules (e.g. carbohydrates) I would have to say there are three atoms which are the basis: carbon, hydrogen, and oxygen.
What elements are found in carbs?
Carbohydrates are composed of carbon, hydrogen, and oxygen atoms. They are usually classified as simple carbohydrates (sugars like glucose and fructose) or complex carbohydrates (starches like in grains and vegetables). Fiber, which is a type of carbohydrate that our bodies can't fully digest, is also commonly found in carbohydrate-containing foods.
What is the human body mostly made of a carbon oxygen nitrogen and hydrogen b oxygen calcium carbon and hydrogen c hydrogen iron nitrogen and oxygen?
The human body is made up of only mostly carbon, oxygen, hydrogen, nitrogen, calcium, and phosphorus. The top four elements are oxygen, carbon, hydrogen and nitrogen, so that would be a. on your list.

The key elements for a fire?
Fuel, Oxygen and Heat Fuel, Oxygen and Heat Fuel, Oxygen and Heat

That answer would be carbon Sources: Biology teacher.
What is a mixture of carbon dioxide oxygen hydrogen?
This would be a gas mixture containing carbon dioxide, oxygen, and hydrogen. It is important to note that this particular combination is not commonly found in nature and would likely require intentional mixing of gases by humans.
What are the 3 most common elements found in living things important to the human body?
The three most common elements found in living things and important to the human body are carbon, hydrogen, and oxygen. These elements play a crucial role in forming organic molecules such as carbohydrates, lipids, proteins, and nucleic acids essential for life processes.
What is the chemical name for Carbon 12 Hydrogen 22 and Oxygen 11?
The chemical name for Carbon 12 Hydrogen 22 and Oxygen 11 would be C12H22O11, which is commonly known as sucrose or table sugar.
What mineral that contains oxygen carbon and metallic element magnesium would be classified as?
If it contain magnesium but no calcium then it would be magnesite.
How many atoms of carbon hydrogen and and oxygen are in two molecules of pyruvic acid?
Each molecule of pyruvic acid has 3 carbon atoms, 4 hydrogen atoms, and 3 oxygen atoms. Therefore, two molecules of pyruvic acid would have a total of 6 carbon atoms, 8 hydrogen atoms, and 6 oxygen atoms.
Which to atoms are the most common in the earth crust?
Hydrogen, Carbon, Oxygen, and Silica are the most common elements found in the Earth.
What compound contains carbon hydrogen oxygen?
Any alcohol would contain these 3 elements.
