Which statement describes a chemical property of water?

Question

Which statement describes a chemical property of water? It reacts with sodium metal. It has a melting point of 0°C. It has a density of about 1 g/mL. It is clear and colorless.

Baron Dickinson · Accepted Answer

first option, It reacts with sodium metal.Explanation:Chemical properties are those manifested only as part of a chemical reaction, which means that the composition of the molecules of water will change: some chemical bonds are broken and others are formed, transforming some pure substances (elements, like sodium, or compounds, like water) into one or more different pure substances. Water has the ability to react with sodium metal for form sodium hydroxide and hydrogen gas, according to this reaction: Na(s) + H₂O (l) → NaOH (aq) + H₂ (g).The products formed have different composition and different physical and chemical properties than the reactants from which they originated from. This is what a chemical change means.2) On the other hand, the melting point of 0°C, the density of about 1 g/mL, and that it is clear and colorless, are all physical properties, because they can be assesed without changing the composition of water.

The statement that describes a chemical property of water is this: IT REACT WITH SODIUM METAL.Substances generally have two types of properties, these are chemical and physical properties. Physical properties of matters refer to those characteristics of matter which can be observed without changing the composition or nature of the matter. Examples of physical properties are color, boiling point, melting point, etc. Chemical properties on the other hand are those properties that can only be observed by changing the chemical nature of the substance. For instance, the chemical reaction of a substance with another substance will showcase the chemical properties of those substances.

The chemical description of water is H2O, which means, it is composed of 2 hydrogen atoms and 1 oxygen atom. The answer to this item is the fourth option, " It is clear and colorless." When water is added with calcium, clear, colorless bubbles are formed. This explains a reaction of water with acid. The following are additional facts about water properties: Density: 1 g/cm³Boiling point: 100 °CMolar mass: 18.01528 g/molMelting point: 0 °CFormula: H2O
