Answer:
- Calcium is homogeneous Three percent of Earth's crust is made of calcium
Mineral
-
Glycerin is a viscous liquid
at room temperature. Non-mineral
-
Emerald is hard and does not decay. Its chemical formula is Be3Al2(SIO3)6 Mineral
- Chlorophyll is produced in plants
during photosynthesis Non-mineral
Explanation:
Minerals are generally solid and inorganic substances, with defined crystalline structures, that exist in the earth's crust, formed by one or more chemical elements.
Calcium is the fifth element in abundance in the earth's crust, it is found forming mineral compounds such as calcite and dolomite or rocks such as marble, limestone and dolomite.
Glycerin is a colorless, slimy and sweet-tasting substance that is obtained from animal and vegetable fats and oils. According to its characteristics, it does not have a solid structure, which is why it is considered a non-mineral.
Emerald is a cyclic silicate of beryllium and aluminum whose chemical formula is Be3Al2(SiO3)6, it has a well-defined crystalline structure.
Chlorophyll is a green pigment that is present in the leaves and stems of many vegetables and is responsible for the photosynthesis process; does not have a crystalline structure defined by what is considered a non-mineral.
The chemical formula of water is written as H2O we can just use the ratio of the atoms since we are not given the reaction. Hydrogen is a diatomic substance so that it exists as H2. We calculate as follows:
0.253 mol H2O ( 1 mol H2 / 1 mol H2O ) = 0.253 H2 needed
Hope this answers the question. Have a nice day.
