Answer:
c. Atoms of two or more elements bond together
Explanation:
a chemical reactions forms products ( new substances); where it rearranges themselves to form new bonds.
Answer:
Option A
Explanation:
An intensive property is a bulk property, meaning that it is a local physical property of a system that does not depend on the system size or the amount of material in the system. Examples of intensive properties include temperature, T; refractive index, n; density, ρ; and hardness of an object,specific heat, η.
Physical properties can be observed or measured without changing the composition of matter. Physical properties are used to observe and describe matter. Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, specific heat and many others.
No, I don’t think so. My reason being that some of these viruses are not harmful, an example is bacteriophage which kills bacteria.

At first we thought atoms were just electrons and were negatively charged, but now we’ve learned that is can create different and many more substances.
