Is reacts with acid to form H2 a chemical or physical properties?
This is a chemical property, as it involves a chemical reaction where hydrogen gas is produced when the substance reacts with an acid. Physical properties refer to characteristics such as color, state, density, and boiling point.
Is mixing two substances and light is produced a chemical or physical change?
If light is produced when two substances are mixed, it is most likely a chemical change. Chemical changes involve the formation of new substances with different properties, whereas physical changes typically only affect the state or appearance of a substance without altering its chemical composition.
When a substance undergoes a phase change what occurs a particle change a chemical change a new substance is formed a physical change?
During a phase change, the substance transitions between different states of matter (solid, liquid, gas) without any change in the chemical composition of the particles involved. This means that there is no new substance formed and no chemical change taking place, it is solely a physical change.
Is heating KClO3 and MnO2 a chemical or physical change?
Heating KClO3 and MnO2 to form KCl and MnO2 is a chemical change as new substances are being produced.
Does smoke of a vehicle a physical or chemical change?
The smoke produced by a vehicle is a combination of physical and chemical changes. The combustion of fuel in the engine is a chemical change that produces gases, while the dispersal of these gases into the air involves physical changes such as condensation and diffusion.
What is mineral crystals of quartz biotite mica and amphibole are produced primarily by?
Mineral crystals of quartz, biotite mica, and amphibole are primarily produced by the process of crystallization from a cooling magma or lava. As the molten rock cools and solidifies, these minerals crystallize out of the melt based on their individual chemical and physical properties, forming distinct mineral crystals.
Sunlight produced into stored energy physical or chemical change?
chemical change
Are pop cans a physical or chemical change?
Pop cans are produced by physical processes.
Is the sun's energy is produced by physical and chemical changes in the interior?
False
Is reacts with acid to form H2 a chemical or physical properties?
This is a chemical property, as it involves a chemical reaction where hydrogen gas is produced when the substance reacts with an acid. Physical properties refer to characteristics such as color, state, density, and boiling point.
Are the changes produced by electrolysis chemical or physical in nature?
The changes produced by electrolysis are chemical in nature. The process involves the conversion of electrical energy into chemical energy, resulting in the decomposition of compounds into their constituent elements or ions.
When iron is immersed in a solution of hydrochloric acid hydrogen gas is produced a physical or chemical property?
This is a chemical reaction.
Is a bomb exploding a physical change?
An atomic bomb uses fission-- the splitting of atoms. It is purely a physical change, at first. Any gases produced in the air surrounding the explosion (which occurs before it touches the ground), along with the intense heat produced, causes chemical changes in the air.
Why physical changes can easily be reversed but why chemical cannot?
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
Why physical change can easily be reversed but chemical change cannot?
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
Explain Why physical changes can be reversed but chemical changes cannot?
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
