The Sea and the ocean are just different terms that mean same thing
Answer:
I know its not Oxygen (O2) because we need that gas to breath if not more of that gas! and i know its not helium because it is not very toxic and not a crisis in the world
Your answers are going to be B. and D.
have a nice day!
The answers to the questions are as follows;
- It would gain three electrons
- The difference in their electronegativities.
- The elements have filled Valence levels
- potassium (K) with a 1+ charge
- ClO-
Question 1:
- How would the electron configuration of nitrogen change to make a stable configuration?
Since Nitrogen has 5 Valence electrons, it needs 3 electrons to attain it's octet configuration. As such, it gains 3 electrons.
Question 2:
- Which quantity determines how two atoms bond.
The quantity which determines how two atoms bond is The difference in their electronegativities.
Question 3:
- Which statement best explains why the elements in Group 18 do not have electronegativity values.
This is because the elements have filled Valence levels.
Question 4:
- Based on patterns in the periodic table, which ion has a stable valence electron configuration
The ion which has a stable Valence electron configuration is potassium (K) with a 1+ charge
Question 5;
- Which chemical formula represents a polyatomic ion?
The chemical formula which represents a polyatomic ion is; ClO-
The continental drift is what caused plate tectonics
Answer:
The mass of the surrounding is 
Explanation:
From the question we are told that
The mass of 
is 
The mass of water is 
The chemical equation for the dissociation process is
The specific heat capacity of the mixture is 
The combined mass of the solution is
The mass of the surround here is the mass of the coffee-cup calorimeter and this contain the mixture ( water and the NaOH ) so the mass of the surrounding is
