In chemistry, a chemical change is a change which involves the production of new chemical substances. Frying an egg is an example of a chemical change because of the reaction between the oil and the substance in the presence of supplied heat.
Answer:
C6H12O6.
Explanation:
Adding up the relative atomic masses of the elements
C + 2H + O
= 12 + 2*1 + 16.
= 30.
180 / 30 = 6 so the molecular formula is:
C6H12O6.
A solid is an object that has definite shape, volume, and mass. This means that the shape, volume, and mass will never change.
A liquid is something that has definite volume and mass, but it does not have definite shape because a liquid is the shape of its container.
A gas <span>does not have a definite shape, mass, or <span>volume because a gas is able to spread around.</span></span>
