Chemistry
2 answers:
Maslowich2 years ago
6 0

Minerals are inorganic solids that develop in nature and have a crystalline structure as well as a specific spectrum of chemical formulas. Ores are areas of mineral concentration in rock that may be economically mined for use. Lodestone is one of the iron ores. The mineral known as ore is where metal is easily and affordably mined. The composition of ore is known. Minerals are naturally occurring metals that are found in the crust of the planet. Ores are minerals that can be utilized to profitably extract metal.

Answer:

<em>Minerals are naturally occurring inorganic solids with a crystalline structure and a definite range of chemical formula. Ores are concentrations of minerals in rock that are high enough to be economically extracted for use. All ores are minerals, but all minerals are not necessarily ores.</em>

Hope its helpful!

Calcum chloride contains only calcum and chloride What is the fomula for this compound? fou need the Peodie Table for thia quest
mafiozo [28]

Answer:

CaCl_2

Explanation:

Calcium is the element of the group 2 and period 4 which means that the valence electronic configuration is [Ar]4s^2.

Chlorine is the element of the group 17 and period 3 which means that the valence electronic configuration is [Ne]3s^23p^5.

Thus, calcium losses 2 electrons to 2 atoms of chlorine and these 2 atoms of chlorine accepts each electron to form ionic bond. This is done in order that the octet of the atoms are complete and they become stable.

Ca         Cl

2            1

Cross multiplying the valency, We get, CaCl_2

Thus, the formula of calcium chloride is CaCl_2.

Fluorine (F) has seven electrons in its outermost shell. Fluorine _____.
kow [346]
Fluorine is a nonmetal and as such it would need to take in or obtain an electron from a metal to have a stable octet, or full number of 8 electrons in its valence shell. Thus due to the indifference of electrons and protons it becomes an anion, a negatively charged ion.
