What are properties of elements compounds and mixtures?
Here are some characteristics of compounds:Compounds are made up of 2 or more elements and they are all chemically bonded.The properties of a compound are different from the elements that make it up.Compounds can be broken back into elements by chemical reaction, exposure to light, etc.Compounds can be separated only chemically, not by physical meansThe mass of the compound is determined by the mass of the elements that make it up.When compounds are formed heat and light is given out or absorbed.Compounds have definite proportions.
Are the compounds often very different from those of the elements that make it up?
Yes, compounds have different properties than their constituent elements because the atoms in a compound combine to form new chemical bonds and structures. This results in unique physical and chemical properties not seen in the individual elements.
What is the equation of magnesium nitrate with an excess of sodium phosphate to make sodium nitrate and magnesium phosphate.?
The balanced chemical equation for this reaction is: 3Mg(NO3)2 + 2Na3PO4 -> 6NaNO3 + Mg3(PO4)2
Is reaction to oxygen a physical or chemical?
Reaction to oxygen is a chemical process because it involves the formation of new substances through the rearrangement of atoms. This process can result in the formation of oxides, such as rust in the case of iron reacting with oxygen.
What are minerals composed of?
Minerals are naturally occurring inorganic solid substances composed of one or more chemical elements arranged in a specific crystalline structure. They have a definite chemical composition and physical properties, such as hardness, luster, and color. Minerals make up the Earth's crust and are essential for various industrial and biological processes.
What elements make up aluminium phosphate?
Aluminium phosphate is composed of aluminium (Al), phosphorus (P), and oxygen (O) atoms. The chemical formula for aluminium phosphate is AlPO4.
What elements make up disodium phosphate?
Sodium and phospherous
Make you a sentence using periodic law?
The periodic law is a law that states that the repeating chemical and physical properties of elements change periodically.
What elements make up acetic acid in the physical and chemical changes of science?
a chemical chang is a chang that ends up in a new subtanes im in 5 grade and i know that
Is break glass a physical?
yes, breaking glass changes the physical properties of the piece, while a chemical change would be removing one of the elements that make up the glass
How does two elements make a compound?
After a chemical reaction two elements form a chemical compound.
Is combining hydrogen and oxygen to make water is a physical?
No.
Describe the processes that must occur in order to make rock phosphate available to plants again?
Rock phosphate needs to weather and break down over time due to physical, chemical, and biological processes. Physical weathering includes actions like freezing/thawing, while chemical weathering involves reactions with water and oxygen. Additionally, biological processes such as plant roots and microorganisms play a role in releasing phosphorus from rock phosphate for plant uptake.
Is decompositon a chemical property?
A physical property is part of the make up of something that has a physical mass. No decomposing is not a physical property but rather both a physical change and a chemical change hence changing the chemical properties . The physical change is when the mass changes due to the brake down of the chemical and physical properties.
Is absorbency a chemical or physical property?
Scientists make a distinction: physical absorption (without chemical reaction) and chemical absorption (involving a chemical reaction).
What is the elements make up in iron phyrophosphate?
Pyrophosphate has the chemical formula (P2O7)-4. It is a class of chemical anions that were originally formed from heating (pyro) phosphates. They are formed by esterification of two phosphates (linking them with one of the phosphate oxygen atoms).
Is boiling water to make a soup Physical or chemical change?
Physical
