Carla made models of a water molecule and a hydrogen peroxide molecule. Oxygen atom Oxygen atom Hydrogen atom Hydrogen atom Hydrogen atom Oxygen atom Hydrogen atom Hydrogen peroxide Water Carla also observed some properties of water and hydrogen peroxide. She recorded her observations in this table. Carla's Observations Property Water Hydrogen peroxide Color clear clear State liquid liquid Odor none none Based on her observations, Carla concluded that water and hydrogen peroxide are the same substance. Is Carla's conclusion correct and why? O A. No, her condlusion is not correct. They are different substances because they have different names. O B. No, her conclusion is not correct. Molecules with a different number of the same atoms are different molecules. C. Yes, her conclusion is correct. They have the same properties and the same atoms. D. Yes, her conclusion is correct. Hydrogen peroxide is the scientific term for water.
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
