What is the identity of a substance?
The identity of a substance (chemical compound) is defined by his chemical formula and molecular structure.
How do you recognize that two molecules are indeed isomers?
They will have the same molecular formula (or at least the same numbers of constituent atoms.)
Which formula represents an electrolyte?
NH4Cl (it stays together with ionic bonds)
How do scientists show the chemical composition of molecules?
The most common and simplified method and convention of notating elemental composition and molar quantities of molecular compounds comes through their molecular formula. In water, its formula is H2O indicating it contains a single atom of oxygen and two of hydrogen.
What is the molecular formula based upon?
The formula is based on the chemical composition of the molecule.
What are the molecules that share the same chemical composition but differ in molecular structure?
isomers
How many atoms has at least a single molecule?
Molecules are composed of atoms, not the other way around. The quantity of molecules needed for a component of a gas, liquid, or solid will depend upon the chemical composition and molecular structure.
What molecules are identical in chemical composition but differ in structure?
hydrocarbons, they are called isomers
What kind of process alters molecular composition?
A chemical reaction alters molecular composition.
Is displaces hydrogen from an atom a physical or chemical property?
Chemical because it's breaking apart the molecular structure of the water molecules.
Can molecular structure of sunlight change random?
Sunlight is not made of molecules and therefore has no "molecular structure."Sunlight can induce certain types of chemical changes in molecules that it hits; however, these are not "random" but fall into certain well-defined classes.
What are related to chemistry?
Chemistry is the study of chemical composition of materials, of chemical reactions, of the structure of molecules, of molecules synthesis, etc. Chemistry is close to physics, mineralogy, biology.
What is the identity of a substance?
The identity of a substance (chemical compound) is defined by his chemical formula and molecular structure.
How do you recognize that two molecules are indeed isomers?
They will have the same molecular formula (or at least the same numbers of constituent atoms.)
What is a key feature of a chemical change?
Any change that changes the atomic and molecular composition and structure of the substances involved. Mostly it is a physical change that cannot be reversed.
Which formula represents an electrolyte?
NH4Cl (it stays together with ionic bonds)
Is a car wreck a chemical change or a physical change?
When a car is turned into a wreck, this involves a physical change because the molecular composition of the car doesn't change. After the crash it will still consist of steel, petrol, etc. However, if one was to set fire to the car, it would undergo a chemical change: its molecular composition would change because the molecules would bind with the oxygen molecules in the air.
