Answer:
I think you meant rock defination in science
Explanation:
A rock is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. It is categorized by the minerals included, its chemical composition and the way in which it is formed. Rocks are usually grouped into three main groups: igneous rocks, metamorphic rocks and sedimentary rocks.
or
A rock is a solid made up of a bunch of different minerals. Rocks are generally not uniform or made up of exact structures that can be described by scientific formulas. Scientists generally classify rocks by how they were made or formed. There are three major types of rocks: Metamorphic, Igneous, and Sedimentary.
Mass is equal to moles x molar mass, and the molar mass of C6H12 is 84, therefore the mass is 436.8 g, but 437 rounded to correct significant figures
Answer:
25% gold.
Explanation:
6 is 25 percent of 24, so 6 karat gold would be 25% gold.
There are multiple factors that contribute to the cost of a mineral.
First of all is the demand or application, which will be related to its
physical properties. For example, nontarnishing metals like gold are
held in high value for their appearance. Second is the supply of the
mineral, those that only have a small quantity in the earth's crust are
likely to be more expensive. Third is the cost of extraction and
manufacturing. Some minerals may be abundantly found, but may be
distributed over a wide area, meaning that it is still expensive to mine
and transport.
Plants can reproduce through either sexual or asexual means. Sexual reproduction involves pollination helped by wind and or insects. Asexual reproduction involves tubers, bulbs and runners known as rhizomes and stolons as well as cuttings taken by humans.
