Crushing a rock does not change the chemical identify of it's constituent compounds. Therefore, crushing a rock is a physical change.

O dropping a penny into a glass of water crushing of stone a burning candle O dissolving sugar in water O melting of lead Question 8 If the radius of a silicon atom is 1.18 x 108 cm, what is the radius in nm?

Answer and Explanation: Crushing is a physical property. Physical properties are those that can be measure without changing the chemical composition of the substance being studied. The property of a substance to be crushed would not change its chemical composition when it is measured.

Crushed stone is obtained quite simply by crushing various rocks, such as gravel, boulders, and various simultaneously mined interfering rocks or waste from non-conditioning. Crushers of different designs are used to produce crushed stone: roller, cone, cheek crushers [3-6]. Roll plants crush stone as a result of its crushing.

These are not definite indicators; a chemical reaction may not be occurring. A change in color is not always a chemical change. If one were to change the color of a substance in a non-chemical reaction scenario, …

There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as " clinker," together with some 5 percent of gypsum (to control the time of set of the cement).

The process involves grinding silicate minerals to a powder and spreading it on the land surface where it reacts with CO 2 and removes it from the atmosphere—a process known as the abiotic ...

In certain cases, stone washing is required to meet particular end product specifications or demands as with concrete aggregate processing. Crushed and broken stone normally is not milled but is screened and shipped to the consumer after secondary or tertiary crushing. 11.19.2.2 Emissions And Controls1-8

Answer. Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve.

Physical Change – does not produce a new substance (e.g., phase changes, crushing a can) stone Change – produces a new substance (e.g., burning, rusting, photosynthesis)

A chemical reaction produces new substances, unlike the chopping process which only changes the wood's physical form. Explanation: In the given list, only chopping a log into sawdust is not an example of a chemical reaction. A chemical reaction is characterized by the production of one or more types of matter that differ from the matter …

A more convenient way to express a chemical reaction is to use the symbols and formulas of the substances involved: Zn + S → ZnS (10.4.2) (10.4.2) Zn + S → ZnS. The substance (s) to the left of the arrow in a chemical equation are called reactants. A reactant is a substance that is present at the start of a chemical reaction.

I don't think so. A chemical change implies changing molecular-level structure usually accompanied by transferring electrons. When you squish an avocado you're only rearranging the fats, carbohydrates, and fiber in it - I don't think a chemical reaction occurs. If you left it out, and it turned brown (oxidized), that would be a chemical change!

Mechanochemistry also offers possibilities for manufacturing pharmaceutical molecules, continuing the long history of connections between crushing and medicine. A twin-screw extruder grinds together solid reactants, triggering a chemical reaction without liquid solvents. Scientists have used extrusion to make muscle relaxants and antibiotics.
