What elements did John Dalton discover the atomic weights of?
John Dalton determined the atomic weights of several elements, including hydrogen, oxygen, carbon, nitrogen, and sulfur, among others. He used hydrogen as the reference point with an atomic weight of 1, assigning relative weights to other elements based on their combinations with hydrogen. Dalton's work laid the foundation for the modern understanding of atomic theory and the relative weights of elements. His findings were crucial in advancing the field of chemistry in the early 19th century.
Do carbon and oxygen have the same atomic mass?
They don't contain the same number of particles because some particles are more dense than others making one atom and another atom the same mass but not have the same number of particles.
A form of an element that differs in its atomic weight from other forms of that same element is?
Elements that differ in atomic weight from other atoms of the same element (ie their atomic masses are different to each others due to a different number of neutrons) are known as isotopes. Example: carbon-14 which has 6 protons and 8 neutrons in its nucleus and an atomic mass of 14, as opposed to regular carbon (carbon-12) which has 6 protons and 6 neutronsin its nucleus, and an atomic mass of 12. Carbon-14is an isotope of carbon.
What is the atomic mass of milk?
Milk is a solution of many different atoms. Atomic mass only refers to the mass of a single type of atom. Milk may have a "molecular mass" but you need to determine all of the different atoms in milk and then add their masses together.
How many protons are in a tree?
The number of protons in a tree depends on its specific molecular composition. Trees, like all living organisms, are primarily made up of elements such as carbon, hydrogen, oxygen, nitrogen, and others, each with a distinct number of protons in their atomic structure. For example, carbon has 6 protons, oxygen has 8, and hydrogen has 1. To determine the total number of protons in a specific tree, one would need to analyze its molecular makeup and calculate accordingly.

What elements are found in a candy cane?
Carbon Hydrogen and Oxygen (with very small traces of others).
What cotains two or more elements?
A water molecule is composed of elements hydrogen and oxygen. H2O Carbon dioxide is composed of carbon and oxygen. CO2 Methane, ethane, propane, butane and many others are composed of just carbon and hydrogen.
What is the element on wich life is based?
Carbon mostly, we are made of carbon chain molecules with things like oxygen, hydrogen, and Nitrogen (there are others as well)
What element is the main component of carbohydrates?
The word "carbohydrate" is made up of the names of three elements: carbon, hydrogen and oxygen. Which is the main one? Well, the hydrogen will outnumber the others but carbon is the backbone of these molecules, so you pick.
Why did America keep in secret the development of atomic and hydrogen bombs?
Britain and Germany, amongst others, were also developing atomic bombs. You don't allow your enemies in a war know what you are doing!
What chemical elements are in hay?
Carbon, hydrogen, oxygen, nitrogen, and traces of all the others.

Is helium or carbon or hydrogen or beryllium the best ideal moderator for use in the core of a nuclear reactor?
Carbon is a very good moderator, for use in gascooled reactors, the others not.

What element is needed for living organism to survive?
Oxygen, but we also need carbon, hydrogen, nitrogen and many others as well.
