Master Combination Reactions

A combination reaction is a chemical reaction where two or more substances combine to form a single product.

One example of a combination reaction is the reaction between hydrogen gas and oxygen gas to form water.

The general equation for a combination reaction is A + B → AB, where A and B are the reactants and AB is the product.

<p>The modern periodic table is organized based on the atomic number of elements and their properties. It consists of rows called periods and columns called groups.</p> Signup and view all the answers

<p>The periodic law states that the properties of elements are periodic functions of their atomic numbers. This law helps in predicting the properties of elements based on their position in the periodic table.</p> Signup and view all the answers

<p>The modern periodic table is based on the atomic number of elements, whereas Mendeleev's periodic table was based on atomic masses. Additionally, the modern periodic table has a more precise arrangement of elements and includes the noble gases.</p> Signup and view all the answers

<p>The periodic law states that the physical and chemical properties of elements are periodic functions of their atomic numbers. The modern periodic table is organized based on this principle, with elements arranged in order of increasing atomic number.</p> Signup and view all the answers
