The features that can be observed from a substance that undergoes a chemical change is that the shape is altered. That is option D.
<h3>What is a chemical change?</h3>
A chemical change is the change in which two or more chemical substances involved in a chemical reaction rearranges their chemical bonds to form a new product.
In the chemical change, the shape of an object can be changed and the object will still remain true to its chemical composition.
Therefore, the features that can be observed from a substance that undergoes a chemical change is that the shape is altered.

Yes because Na is a metal and Cl is a nonmental, so they criss cross charges, as Na is 2+ and Cl is 2-, 2+ indicates that Na gives AWAY electrons to Cl and the 2- on Cl indicates it receiving electrons. NaCl is table salt and forms a crystal lattice structure, which is why salt is solid at room temperature.
Answer:
it will affect the mass by changing in pressure will affect the volume (and therefore density) of gases, but will not noticeably affect the volume (or density) of solids and liquids. For gases: An increase in pressure leads to a decrease in volume and an increase in density. A decrease in pressure leads to an increase in volume and an decrease in density.
Explanation:
