Answer: Water
Explanation: I don't see any graph attached, but water has a boiling point of 100C, which is where it would become gas, or water vapor. 0C is the freezing point of water, where it would become ice. Since 50C is in the middle, it would be considered liquid.
Answer:
2.29 × 10²⁴ atoms Na
Explanation:
Step 1: Define
Avagadro's Number: 6.02 × 10²³ atoms, molecules, formula units, etc.
Step 2: Stoichiometry
= 2.2876 × 10²⁴ atoms Na
Step 3: Simplify
We have 3 sig figs.
2.2876 × 10²⁴ atoms Na ≈ 2.29 × 10²⁴ atoms Na
Answer:
I'm pretty sure this is a question about your opinion so there is no wrong answer! Just think about the question and if you were in those shoes. There is no right or wrong answer! :)
Explanation:
Answer:
1) 8 valence electrons are a full shell that makes the atom more stable.
Explanation:
Due to the octet rule, atoms tend to form compounds in ways that give them eight valence electrons and thus give them the electron configuration of a noble gas, making them stable.
