Describe how the stone could change and what types of wheathering will cause these changes?
Stones can change through physical weathering, where processes like freeze-thaw cycles or abrasion break them down into smaller pieces. Chemical weathering can also alter stones by reacting with minerals in the stone, causing them to dissolve or change composition. Biological weathering, such as the growth of plants or organisms on the stone, can also cause changes over time.
Which one of the following contaminantes is a physical contaminant?
A physical contaminant is typically a foreign object that can cause harm or injury when ingested or encountered. Common examples include glass shards, metal fragments, stones, or pieces of plastic. Unlike chemical or biological contaminants, physical contaminants result from human error or mishandling rather than from chemical reactions or microbial growth.
What are the Basic chemical types of urinary calculi?
The basic chemical types of urinary calculi are calcium stones, which are the most common and can be either calcium oxalate or calcium phosphate; struvite stones, which are made of magnesium, ammonium, and phosphate; uric acid stones; and cystine stones.
How do you separate beans and stones using chemistry ways?
To separate beans from stones using chemistry, you can utilize the differences in density and solubility. One method involves creating a saltwater solution: when the mixture is added, the beans will float while the stones sink, allowing for easy separation. Alternatively, if the stones are soluble in certain solvents while the beans are not, you could dissolve the stones in the appropriate solvent and then filter out the beans. Both methods leverage the distinct physical and chemical properties of the materials involved.
Can precious stones be melted together?
Yes, some precious stones can be melted together to create a new material, usually known as a synthetic or composite gemstone. However, the process can be complex and may alter the physical and chemical properties of the stones involved. It is important to consult with a professional gemologist before attempting to melt precious stones together.
Is testing stones with acid to see if they are marble a chemical change?
No, testing stones with acid to see if they are marble is a physical change. The acid reacts with the marble to produce a fizzing or bubbling reaction, indicating the presence of calcium carbonate in the marble. This reaction does not change the fundamental chemical composition of the marble.
Are stones abiotic and biotic?
Stones are abiotic, just as soil is. Abiotic factors are the physical and chemical factors in an ecosystem whereas biotic factors are the living (or once living) factors in an ecosystem. Therefore, as stones have never been living, they are NOT BIOTIC.

What is your weight in stones?
I do not have a physical form or weight, as I am a virtual assistant.

What are Mount Rushmore physical characteristics?
Mt. Rushmore IS a physical feature BECAUSE, it is rocks and stones.
What are the 3 types of food contamination and give example to each?
Within USDA FSIS (Food Safety and Inspection Service), there are three categories of hazards that must be addressed within the regulated establishment's HACCP plan - chemical (cleaners, sanitizers, preservatives, etc.), biological (E. coli, Salmonella, Listeria monocytogenes, etc.), and mechanical (foreign particles, wood chips, metal flakes, etc.).
How are kidney stones formed?
Kidney stones are hard crystal-like structures that are formed in the kidneys from chemical elements in urine. More men are affected by kidney stones than women.
What are some good effects of physical change?
Some good effects of physical changes: Material or substance remains unchanged, Castings, Sculptures, Shaping of metals, Shaping of stones for building, Polishing of metals and stones.
What is the chemical name for kidney stones?
normally it is calciun oxilate(check my spelling).
