How does certain metal and rocks create sparks?
The sparks are created from the rapid oxidation of small particles of reactive elements.
What are the similarities between electronic structure of sodium and fluorine?
There is no particular similarity between the electronic structure of the elements sodium and fluorine. Their electronic structures are similar only to the extent that all elements have certain features in common. The electrons form shells around the nucleus. This is true of sodium and fluorine as well as all other elements.
A certain igneous rock contains about 25 percent dark silicate minerals The remainder of the rock is mostly plagioclase feldspar What type of composition does tthis igneous rock have?
ultramafic
What is mean by a potential difference?
Another name for potential difference is voltage.
What does the word campy mean?
It means an exaggeration of certain elements, almost always intentional, to create a satirical environment. It mostly pertains to certain films or television shows. A good example of a campy film would be an early James Bond film, where espionage activities are exaggerated to the point where they become funny.
Is it that a mineral always contains certain elements in definite proportions?
yes, it is true!
Is there fowlloing sentence true or false?
A mineral always contains certain elements in definite proportions
When geologist say that a mineral always contains certain elements in the definite proportions they mean that the mineral has a definite?
A chemical formula.
Is it true that a mineral always contains certain elements in definite proportions?
Yes, minerals have a specific chemical composition, meaning they contain certain elements in definite proportions. This is a characteristic feature of minerals that distinguishes them from other natural substances.
Does a mineral always contain certain elements in definite proportions?
No, a mineral does not always contain certain elements in definite proportions. While minerals have a specific chemical composition, the proportions of elements can vary within certain limits and still be considered the same mineral.
When geologists say that a mineral always contains certain elements in definite proportions they mean that the mineral always has what?
When geologists say that a mineral always contains certain elements in definite proportions, they mean that the mineral always has a specific chemical composition. This composition is a key characteristic that helps identify and classify minerals. Minerals are composed of specific elements arranged in a precise crystal lattice structure.
Is the sentence true or false each piece of mineral has the same crystal structure?
that question iz absolutely trueFalse
Does a mineral always contain certain elements definite composition?
yes
What do scientists use to calculate the age of an object by measuring the proportions of the radioactive isotopes of v equals certain elements?
See the link below.
Why do elements join to form compounds in specific ratios?
Elements join to form compounds in specific ratios due to the laws of chemical combination, namely the law of definite proportions and the law of multiple proportions. These laws dictate that elements react in consistent and predictable ratios based on the number of atoms involved in the reaction. This results in compounds with fixed compositions.
Who wrote the law of definite proportions and Law of multiple proportions?
The Law of Multiple Proportions was developed by John Dalton based on the Law of Definite Proportions, was part of what laid the groundwork for his atomic theory, and for the basis of chemical formulas for compounds.English chemist John Dalton
What do Chemical composition describes?
Chemical composition describes the types and relative quantities of elements that make up a substance or material. It provides information about the arrangement and bonding of atoms within the substance, which influences its physical and chemical properties. Analyzing the chemical composition of a substance can help scientists understand its behavior and potential uses.
