Select the statement(s) that are false: Water molecules (H2O) are made up of two oxygen atoms and one hydrogen atom. If a substance is water-soluble, it will dissolve in water. Protons, neutrons, and electrons are the subatomic particles that make up an atom. Ions are atoms that have the same number of electrons and protons and therefore have a charge.
Understand the Problem
The question is asking to identify which statements about water molecules, solubility, subatomic particles, and ions are false. Each statement presents information about basic chemistry concepts, and the task requires the ability to assess the accuracy of these statements.
Answer
Statements 1 and 4 are false.
The false statements are: 1. Water molecules (H₂O) are made up of two oxygen atoms and one hydrogen atom. 4. Ions are atoms that have the same number of electrons and protons and therefore have a charge.
Answer for screen readers
The false statements are: 1. Water molecules (H₂O) are made up of two oxygen atoms and one hydrogen atom. 4. Ions are atoms that have the same number of electrons and protons and therefore have a charge.
More Information
The correct composition of water is two hydrogen atoms and one oxygen atom. Ions have an unequal number of protons and electrons, leading to a charge.
Tips
A common mistake is believing ions have equal numbers of electrons and protons. Ensure to remember the correct composition of water.
