What kind of process alters molecular composition?
A chemical reaction alters molecular composition.
Can there be more than the 3 main atoms in water?
Water's molecular composition is H20 which is 2 hydrogen atoms and 1 oxygen atom. The molecular composition cannot change for if it did it would be a different substance.
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.
Can you determine the molecular formula of a substance from its percent composition?
Not completely. The empirical formula of a substance can be determined from its percent composition, but a determination of molecular weight is needed to decide which multiple of the empirical formula represents the molecular formula.
Why does plain water boil faster than salt water?
Salt changes the molecular composition of the water, causing its boiling point to go up. That's why it takes it longer to boil.
Why does plain water boil faster than '?
Salt changes the molecular composition of the water, causing its boiling point to go up. That's why it takes it longer to boil.
Which pair of molecules share the same chemical composition but differ in molecular structure?
Lactose and sucrose share the same chemical composition but differ in molecular structure. Such molecules are called isomers.
What is the Primary molecular composition of chromatids--in addition to protein?
ATP
What properties can help you determine whether a substance is molecular or ionic?
Examples: melting and boiling points, solubility in water or organic solvents, chemical composition.
Is water vapor condensing to form rain a physical or chemical change?
Condensation is a purely physical process (a change of phase). Water evaporating or condensing does not change its molecular composition (H2O).
What is it called when a mixture that appears to the same composition color and density and is mixed at the molecular level?
Solution: A mixture that appears to have the same composition, color, density, and taste, and is mixed at the atomic or molecular level.
What is the chemical composition of earth?
The earth is actually composed of a total of 90 chemical elements. 81 of them have at least one stable isotope.
