kakasveta [241]
<span>The correct answer is that an ionic bond forms between charged particles. To form this bond, the particles transfer valence electrons (those in the outermost orbit). Specifically, in ionic bonding, the metal atom loses its electrons (thus becoming positive) and the nonmetal atom gains electrons (thus becoming negative).</span>

The substances sodium (Na), oxygen (O2), and sodium oxide (Na2O) participate in this chemical reaction:
Andrews [41]

The chemical reaction involving sodium and oxygen as given in the reaction: 4Na + O2 → 2Na2O is a synthesis reaction.

<h3>What are chemical reactions?</h3>

Chemical reactions are changes which occur in the chemical composition of atoms of substances which results in the formation of new substances.

There are different types of chemical reactions such as:

  • synthesis reaction
  • displacement reaction
  • double displacement reactions

A synthesis reaction is a reaction in which two or more substances combine to form a new product.

Therefore, the chemical reaction involving sodium and oxygen as given in the reaction: 4Na + O2 → 2Na2O is a synthesis reaction.

Calculate the mass of silver bromide produced from 22.5 g of silver nitrate.
Orlov [11]
Equation is as follow,

<span>                     2 AgNO</span>₃<span>  +  MgBr</span>₂<span>    </span>→    <span>2 AgBr  +  Mg(NO</span>₃<span>)</span>₂

According to eq.

    339.74 g (2 moles) AgNO₃ produces  =  375.54 g (2 moles) of AgBr
So,
                    22.5 g AgNO₃ will produce  =  X g of AgBr

Solving for X,
                             X  =  (22.5 g × 375.54 g) ÷ 339.74 g

                             X  =  24.87 g of AgBr
