Answer:
B. Argon has similar properties to neon.
Explanation:
hope it helps u.
The statement of element has properties similar to neon is "argon."
What is an element?A substance that cannot be split into smaller components using normal chemical processes. Elements are chemical compounds that correspond to a single spot on the current periodic table. Elements are made up of only one type of atom.
Argon, like neon, is classified as a noble gas. That is, argon is a member of the noble gas family of chemicals.
Both neon and argon are positioned in the group 8, which means they have eight electrons in their outermost electron shell, making them noble and inert gases. They are very nonreactive since they already have a complete and stable octet structure and don't need to connect to other elements.
Hence the correct option is B.

Do covalent bonds form in order to fulfill the octet rule
Answer:
YES
Explanation:
the main reason why bonds form is because the elements wants to be more stable so in a covalent bond the electrons are shared between two elements so they can fulfill or at least "feel" like they have fulfilled there outer shell.

Two students were conducting and experiment based on the ionization energy of alkali metals. The driving question for the experiment was: "What is the relationship between ionization energy and the rate of reaction (time for the reaction to be completed) using alkali metals."
Which of the following predictions would be the best option based on the student's prior knowledge learned and information provided in the graph above?
A.
Cesium will have a higher rate of reaction (faster) because it has the lowest ionization energy which indicates a higher reactivity.
B.
Cesium will have a lower rate of reaction (slower) because it has the lowest ionization energy which indicates a lower reactivity.
C.
The ionization energy of the alkali metals will not affect the rate of the reaction because the energy required to remove an electron does not affect time.
D.
Lithium will have a higher rate of reaction (faster) because it has the highest ionization energy which indicates a higher reactivity.
Answer:
A
Explanation:
Cs has a higher rate of reaction because it's easier to remove an electron from it, thereby leading to faster reactivity

– Why could a flight from California to New York be shorter than a flight from New York to California?
Explanation: Honestly, I have no idea and I've never learned this, but I think it's because of air resistance and currents? Going downwind would mean the plane's rate would be the speed of the wind + the speed of the plane itself. Going upwind, the plane's rate would be the speed of the plane - the speed of the wind. Thus, going one way (e. g. California to New York) could take less time than going the other way.
How many grams of sodium chloride decompose to yield 15 grams of chlorine gas?
2NaCl → 2Na+ Cl2
A- 12.363 9 Naci
B- 49.453 g Naci
C- 30 g NaCl
D- 0.846 g Naci
Answer:
24.6g of NaCl
Explanation:
Expression of the reaction:
2NaCl → 2Na + Cl₂
Given parameters:
Mass of Cl₂ = 15g
Unknown:
Mass of NaCl = ?
Solution:
To solve this problem, we have to use mole relationships.
Find the number of moles of the mass of the given specie;
Number of moles = [tex]\frac{mass}{molar mass}[/tex]
Molar mass of Cl₂ = 2(35.5) = 71g/mol
Number of moles = [tex]\frac{15}{71}[/tex] = 0.21mole
Now;
From the balanced reaction equation;
1 mole of Cl₂ is produced from 2 moles of NaCl;
0.21 mole of Cl₂ will be produced from 0.21 x 2 = 0.42mole of NaCl
So,
Mass of NaCl = number of moles x molar mass
Molar mass of NaCl = 23 + 35.5 = 58.5g/mol
Mass of NaCl = 0.42 x 58.5 = 24.6g of NaCl
