Can we change the ratio between the elements?

A compound is a combination or two or more elements held together by chemical bonds. Compounds can only be separated by chemical processes. Since chemicals are composed of different elements, determining the ratio between the elements can allow you to analyze how much of each compound is present. Such a process is also useful for analyzing chemical reactions that are being performed in chemistry experiments. Making connections between units and how elements combine to form compounds can help you to better understand their ratios.Hydrogen peroxide,H2 O2. There are 2 moles of hydrogen and 2 moles of oxygen giving us a ratio of 2:2. We can reduce this ratio by dividing both numbers by a factor of both of them.
