Answer:
The water phase with the smallest temperature increase when adding 10 kcal of heat is solid ice.
Explanation:
The rest of the statements are incorrect. The density of ice is lower than the density of water. The heat capacity of solid ice is greater almost twice the heat capacity of the liquid water. The heat capacity of vapors is less than heat capacity of liquid.
Answer:
As you go down a group on the periodic table, you get more electron shells and therefore a larger atomic radius.
Mass/ energy can not be created or destroyed
Answer:
An atom of Bromine (Br) forms an ion and becomes Br⁻
Explanation:
- Atoms of elements gain or lose electron(s) to attain a stable configuration and form ions.
- When an atom gains electron(s) it forms a negatively charged ion called an anion.
- For example, Bromine is a halogen and its atom requires to gain one electron to attain stability and form a bromine ion (Br⁻).
- When an atom loses electron(s) it forms a positively charged ion called a cation.
- For instance, atoms of calcium(Ca) requires to lose two electrons to attain stability and form calcium ion (Ca²⁺).
