What kinds of elements form an ionic bond?
Vanyuwa [196]
Ionic bonds usually occur between metal and nonmetal ions. For example, sodium (Na), a metal, and chloride (Cl), a nonmetal, form an ionic bond to make NaCl. In a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals.

<h3>Answer:</h3>

True, the reaction given is an example of a synthesis reaction

<h3>Explanation:</h3>
  • Synthesis reactions are reactions where two or more substances combine to form a single compound.
  • The reaction 2NO(g) + O₂(g) → 2NO₂(g) is an example of a synthesis reaction.

Other types of chemical reactions may include;

  • Decomposition reaction in which a compound is broken down into smaller compounds or individual elements.
  • Replacement reaction where reactive elements replace other less reactive elements in their salts.

10 atoms of aluminum reacts with 6 molecules of oxygen gas to produce aluminum oxide. 4 Al + 3 O2 ––&gt; 2 Al2O3 What is the exc
Mrrafil [7]

The excess reactant is Aluminum.

<u>Explanation:</u>

We have to write the balanced equation as,

4 Al+ 3 O₂ → 2 Al₂O₃

According to the molar ratio 4: 3, from the given balanced equation, we can say that 4 atoms of Al reacted with 3 molecules of oxygen.

Given that 10 atoms of aluminum reacts with 6 molecules of oxygen, as per the ratio only 8 atoms of Aluminum is required to react with 6 molecules of oxygen, so excess reactant is Aluminum.
