The two most abundant elements in the human body are oxygen and carbon. Oxygen plays a crucial role in cellular respiration, while carbon is the building block for all organic molecules.
No. An element is made of only one kind of atom. A compound is made of two or more elements.
A compound is made up of two or more different elements that are chemically bonded together. Each compound has a fixed ratio of elements and distinct properties different from its individual elements.
Any substance made up of two or more elements chemically combined is a compound.
Compounds are substances made up of two or more elements that are chemically bonded together. These elements combine in specific ratios to form distinct compounds with unique properties. Examples include water (H2O) and carbon dioxide (CO2).
Water (H2O), carbon dioxide (CO2), and salt (NaCl) are examples of substances made of two elements.
Lipids are mostly made of hydrogen and carbon atoms. These two elements form the hydrocarbon chains found in lipids, which provide energy storage and structural components in biological systems.
the continental crust is made up of light granitic rocks made up of mostly ________
The atmosphere is the mixture of gas molecules and other materials surrounding the earth. It is made mostly of the gases nitrogen (78%), and oxygen (21%).
Air is made mostly of oxygen (O2) and carbon dioxide (CO2).
Two or more elements.
The mass of the Earth is mostly made up of iron and oxygen. Iron is primarily found in the Earth's core, while oxygen is abundant in the planet's crust and mantle.
A penny is a compound, not an element. Pennies are typically made of a combination of mostly zinc and copper, which are two different elements.
No. An element is made of only one kind of atom. A compound is made of two or more elements.
In chemistry, a "compound" is a substance made up of two or more elements in chemical combination.
All compounds are made of two or more elements.
A compound is made up of two or more different elements that are chemically bonded together. Each compound has a fixed ratio of elements and distinct properties different from its individual elements.
Any substance made up of two or more elements chemically combined is a compound.
