Question

Atoms are neither created nor destroyed during any chemical reaction. Write a 'balanced' equation by determining coefficients that provide equal numbers. For example, hydrogen gas (H2) can react (burn) with oxygen gas (O2) to form water (H20).

a) Hydrogen and oxygen atoms
b) Protons and neutrons
c) Electrons and positrons
d) Neutrons and electrons

Answer 1

To balance a chemical equation, you need to ensure that the number of atoms of each element is the same on both sides of the equation. The balanced equation for the reaction of hydrogen gas (H₂) with oxygen gas (O₂) to form water (H₂O) is 2 H₂ + O₂ → 2 H₂O.

Step-by-step explanation:

To balance a chemical equation, you need to ensure that the number of atoms of each element is the same on both sides of the equation. This is done by placing coefficients in front of the reactants and products. In the given example, the balanced equation for the reaction of hydrogen gas (H₂) with oxygen gas (O₂) to form water (H₂O) is: 2 H₂ + O₂ → 2 H₂O. This equation satisfies the law of conservation of matter, as it has an equal number of hydrogen and oxygen atoms on both sides.
