A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity.
Examples of chemical changes are burning, cooking, rusting, and rotting.
Examples of physical changes are boiling, melting, freezing, and shredding.
Answer:
This formula contains 12 oxygen atoms.
1-They will form the weakest bond.
2-The energy between them begins to decrease as they get closer, and it reaches the minimum when the two atoms are at an optimum distance apart.
3-But once the two atoms forced closer together, So the energy rapidly increases
Considering that the water is at atmospheric pressure, its density at 21°C is still about 0.99 g/mL. The volume of the water is calculated by dividing the given mass by the density. That is,
Volume = mass / density
Substituting the known values to the equation,
volume = 23.2243 grams/ 0.99 g/mL
Simplifying,
volume = 23.46 mL
<em>Answer: 23.46 mL</em>
