Based on the chemical equation, use the drop-down menu to choose the coefficients that will balance the chemical equation: ()zn
Bingel [31]

Based on the chemical equation, to balance the equation we use 2 as a coefficients of HCl on left hand side of reaction.

<h3>What is balanced equation?</h3>

Balanced chemical equations are those equation in which each entities are present in same amount on left side as well as on the right side of the chemical reaction.

Given chemical reaction is:

Zn + HCl → ZnCl₂ + H₂

Above reaction is not balanced equation as number of chlorine and hydrogen atoms are not same, so balanced equation will be:

Zn + 2HCl → ZnCl₂ + H₂

Hence we add 2 as a coefficient of HCl to balance the equation.

german
Halogens are elements that can be found in group 7 of the periodic table. They have 7 electrons in their outer shell and thus can form only a single covalent bond with other elements. Examples of halogens include chlorine, bromine and fluorine. A carbon compound that is covalently bonded with chlorine or bromine is called a halocarbon.

Angelina_Jolie [31]

Answer:

Explanation:

1 . periodicity  

   repeating nature of atomic structure

   Periodicity is the repeating nature or trend of an atom on the periodic table. Periodicity can be inform of ionization energy, atomic radius, nuclear charge etc.

2 . shell

     location of an electron

   Electrons are located in shells. It is where electrons are found in an atom and the probability of finding electrons there are high

3 . non-metals

     high ionization energies

    Non-metals have high ionization energies which is the energy required to remove a loosely bonded electron in an atom. Metals have low ionization energies.

4 . noble gases

       least reactive family

  Noble gases are called inert gases. They have complete electronic configuration and this makes them unreactive.

5 . neutral

       charge on a neutron

   Neutrons have no charge on them. They are subatomic particles found in the nucleus alongside the protons

6 . repel

         like charges

   Like charges repel one another

7 . attract

         unlike charges

  Unlike  charges attracts. Positve attracts negative charges.
