What is a chemical property of water?
The chemical formula of a molecule of water is H2O: two atoms hydrogen (H2) linked to one atom oxygen (O) . Oxygen is more able to keep them close to it than hydrogen. ... The water molecule results to be charged negatively near the atom of oxygen and positively near the atom of hydrogen.

- Water in a pure state has a neutral pH. ...
- Water conducts heat more easily than any liquid except mercury. ...
- Water exists as a liquid over an important range of temperature from 0 – 100° Celsius. ...
- Liquid water is a universal solvent.
What are 5 physical properties of iron?
- It rusts in damp air, but not in the dry air.
- It dissolves readily in dilute acids.
- At room temperature, this metal is in the form of ferrite or α-form.
- At 910°C, it changes to γ-iron, which is much softer in nature.
- It melts at 1536°C and boils at 2861°C.
- Being a metal is magnetic in nature.
What are 3 examples of a chemical property?
The change of one type of matter into another type (or the inability to change) is a chemical property. Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion .
Is turbidity a physical or chemical property?
These properties can be physical, chemical or biological factors. Physical properties of water quality include temperature and turbidity. Chemical characteristics involve parameters such as pH and dissolved oxygen.
What are the 9 physical properties?
Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others .
Does water have a chemical property?
Water is the chemical substance with chemical formula H 2 O, one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom .
What are the physical properties of oxygen?
Oxygen is a colorless, odorless, tasteless gas . It changes from a gas to a liquid at a temperature of -182.96°C (-297.33°F). The liquid formed has a slightly bluish color to it. Liquid oxygen can then be solidified or frozen at a temperature of -218.4°C (-361.2°F).
What are four properties of water?
The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling .
What is the difference between a physical and a chemical property?
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.
Is color a physical or chemical property?
Characteristics such as melting point, boiling point, density, solubility, color, odor, etc. are physical properties . Properties that describe how a substance changes identity to produce a new substance are chemical properties.
What are the similarities and differences between physical and chemical properties?
| Physical property Chemical property | Chemical identity remains the same Chemical identity changes | Structure of material does not change Structure of material changes | No chemical reaction is needed to show the property Chemical reaction is needed to show property |
