Physical and chemical properties can be used to identify an unknown substance by comparing its characteristics to known standards. Physical properties, such as boiling point, melting point, density, and solubility, provide measurable data that can help narrow down possibilities. Chemical properties, including reactivity with acids or bases and behavior under specific conditions, can further confirm the identity of the substance. By systematically analyzing these properties, one can make an informed identification of the unknown substance.

Is zonrox is a sustance or mixtures?
Zonrox is a substance. It is a brand of liquid bleach commonly used for cleaning and disinfecting purposes.
What happen in terms of kinetic theory when you heat a sustance?
When you heat a substance, the kinetic energy of its particles increases, causing them to move faster and collide more frequently with each other. This leads to an overall increase in the substance's temperature and can result in changes such as a phase transition from solid to liquid or liquid to gas.
How cold is something when it feels cold to the touch?
Any substance having temeperature less than body is felt as cold. You appreciate it better if the sustance is having temperature much lower than body temperature and is good conductor of heat. This valid in naturaly found substances like ice. Very cold substances like liquid nitrogen will kill the body cells and are used in cryosurgery.
Does vinegar freeze faster than saltwater?
Hot water will freeze faster than vinegar because the hot water atoms will slow quickly and the vinegar will take longer to freeze because it contains an oil like sustance which take lionger to freeze.
Is a boiling point a chemical property of a sustance?
No, boiling points and freezing points are physical properties.

Is it true that you can touch hardware because it has no sustance?
This statement is not accurate. Hardware, such as computers and electronic devices, is made of physical substances like metals, plastics, and silicon, which have tangible properties. While the term "substance" can refer to various contexts, hardware is indeed physical and can be touched and interacted with in the real world.
The sustance that reduces surface tensin in the alveoli is?
Surfactant is a substance which lines the inside of alveoli. It is composed of a phospholipid bilayer, which have hydrophyllic and hydrophobic properties. This allows it to reduce surface tension.
What type of sustance is crude oil?

What is a measure of movement particles in a sustance?
Temperature.
Is bleach a pure sustance or a mixture?
Bleach is a mixture, typically made up of sodium hypochlorite and water. It is not a pure substance because it contains more than one type of chemical component.
