What represents chemical names of substances in a chemical equation?

In a chemical equation, each element has a symbol (in the periodic table in the elements). You use those symbols to create a chemical equation. For example, water is H2O. "H" represents Hydrogen, "O" represents Oxygen and the 2 means that there are two oxygen particles for each oxygen particle. Together, this creates one water molecule.


How do you test for oxygen concentration in water?

Oxygen concentration in water can be tested using a dissolved oxygen meter or a chemical test kit. The dissolved oxygen meter measures the amount of oxygen dissolved in the water, while a chemical test kit uses reagents to indicate the oxygen level based on a color change. Both methods provide an accurate assessment of oxygen concentration in water.


What is the hypothesis of purifying water?

The hypothesis of purifying water is that the chosen purification method, such as filtration or chemical treatment, will effectively remove contaminants and pathogens from the water, making it safe for consumption. This hypothesis can be tested through experiments that measure the water quality before and after purification to assess its effectiveness.


Chemical formulas represent the number and element of each type of atom in?

a molecule or compound. Each element is represented by its chemical symbol (e.g. H for hydrogen), and the number of atoms of each element is denoted by a subscript following the symbol (e.g. H2O for water).
