Answer : The balanced chemical reaction will be:
Explanation:
Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.
As we know that perbromic acid is considered a strong acid that means it will completely dissociate in water.
The balanced chemical reaction will be:
Mitosis hope that helps i tried:)
Answer:
The elements in same period have same principle quantum number or energy shell.
The elements in same group shows similar chemical and properties.
Explanation:
Inn group:
The elements in same group i.e present in vertical column shows similar chemical properties.
The elements in same group having same number of valance electrons. while in chemical reaction bonds are break and formed and valance electrons are involved. That's why elements in same group having same number of valance electrons and shows similar chemical properties.
In period:
While as we move from left to right the number of valance electron increase by one in every element. But the electron is added in same shell which means that their physical and chemical properties are different but principal quantum number is same.
Answer:
The Aufbau Principle
Explanation:
In the ground state of an atom or ion, electrons fill atomic orbitals of the lowest available energy level before occupying higher-energy levels.
Answer:
b. 0.50 moles
Explanation:
To solve this problem we use <em>Avogadro's number</em> (6.023x10²³ atoms/mol).
By <u>dividing the number of atoms (or molecules) by that number</u>, we can calculate how many moles they represent.
- 3.01x10²³ atoms ÷ 6.023x10²³ atoms/mol = 0.50 moles
So the answer is option b. 0.50 moles.
