What else can I help you with?
What kind of process alters molecular composition?
A chemical reaction alters molecular composition.
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.
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 changes the molecular composition of the water, causing its boiling point to go up. That's why it takes it longer to boil.
Example of miscible?
An example of miscible liquids is ethanol and water. When mixed together, they form a homogeneous solution with uniform composition. This is because the molecular structures of ethanol and water allow them to mix evenly at the molecular level.
Is coal soluble in water?
no it is not because water is too powerful.
Why havey water is havey?
Water is heavy because it has a high density, meaning a large amount of mass is packed into a small volume. This density is a result of water's molecular structure and composition, which contributes to its weight.
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 the molecular abbreviation for water?
The molecular abbreviation for water is H2O.
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.
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.
