Answer: Atoms that make up reactants rearrange into new products

Explanation:

A chemical reaction is the process of breaking down the chemical bonds of the reacting substances which are commonly called as reactants and making new bonds to form new substances commonly called as products.

The products will contain the same atoms as there are in the reactants but the bonds will rearrange to form different substances.

Every chemical reaction is accompanied with absorption or release of energy.

Is heterogeneous a mineral

Dvinal [7]

NOT MY WORDS TAKEN FROM A SOURCE!!!!

Any naturally occurring homogeneous solid that has a definite (but not fixed) chemical composition and a distinctive internal crystal structure.

Minerals are usually formed by inorganic processes.

Synthetic equivalents of various minerals, such as emeralds and diamonds, are manufactured for commercial purposes.

Although most minerals are chemical compounds, a small number (e.g., sulfur, copper, gold) are elements.

Minerals combine with each other to form rocks.

For example, granite consists of the minerals feldspar, quartz, mica, and amphibole in varying amounts.

Rocks are generally, therefore, an intergrowth of various minerals.<span> </span>

Which factors determine the length of a bond between two elements?

Tanya [424]

Answer:

The length of the bond is determined by the number of bonded electrons (the bond order). The higher the bond order, the stronger the pull between the two atoms and the shorter the bond length. Generally, the length of the bond between two atoms is approximately the sum of the covalent radii of the two atoms.
