What are two chemical and two physical properties of water? Please help me. Thank you.

physical properties: boiling point, freezing point,density, color, electrical conductivity

chemical properties: reactivity with sodium. Reactivity and decomposition with electrictiy.

Sure! Let's start with the physical properties of water:

1. Boiling point: The boiling point of water is 100 degrees Celsius (or 212 degrees Fahrenheit) at standard atmospheric pressure. This means that when the temperature of water reaches 100 degrees Celsius, it starts to vaporize and turn into steam.

2. Freezing point: The freezing point of water is 0 degrees Celsius (or 32 degrees Fahrenheit) at standard atmospheric pressure. When the temperature of water reaches 0 degrees Celsius, it solidifies and becomes ice.

Now, let's move on to the chemical properties of water:

1. Reactivity with sodium: Water is reactive with certain metals such as sodium. When sodium comes into contact with water, a chemical reaction occurs, producing sodium hydroxide and hydrogen gas. This reaction is often accompanied by a release of heat and sometimes even a small explosion.

2. Reactivity and decomposition with electricity: Water can also undergo a chemical reaction when exposed to an electric current. This process is called electrolysis, where water molecules break down into hydrogen gas and oxygen gas. This reaction occurs in devices like electrolyzers and is used to produce hydrogen gas as a source of clean energy.

To find these properties, you can consult reliable sources such as textbooks, scientific journals, or educational websites specialized in the subject matter. These sources will provide detailed information on the physical and chemical properties of water, along with experiments and data to support the conclusions.
