Answer: similarities
- there are some cases where the element confer some of its own properties to the compound, so there are properties which are similar between the element and the compound, for example when an element is strongly charged with electrons, the element confer this property to the compound, and this similar between them.
- the other similarity is that both, the compound and element are formed of atoms, electrons and neutrons.
differences
The principal difference is that a element is conformed only by one element but a compound can be conformed for more than two elements.

isotopes have the same atomic number because they are the same element but have a different atomic mass because they contain a different number of neutrons.

Answer:
Gases can be compressed easily because there is a large amount of space between the individual molecules, which are very active and move around at high speed.
Explanation:
When gas is compressed, the particles are forced much closer together, allowing a huge amount of particles to fit in a small space.
You cant its not really that possible there diffrent elements to gather them into one source would be difficult more than likely a scientific explanation would answer this based upon test and research
Answer is: D. It is not sodium bicarbonate.
Balanced chemical reaction of heating sodium bicarbonate: 2NaHCO₃ → Na₂CO₃ + CO₂ + H₂O.
This is chemical change (chemical reaction), because new substances are formed (sodium carbonate, carbon(IV) oxide and water), the atoms are rearranged, so there is no sodium bicarbonate (NaHCO₃) in the test tube.
