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 formula for phosphorus is P4
Answer:
Na(OH)4
Explanation:
Look at the charges and add them up
Na(OH) Na(OH)
Answer:
Explanation:
The stoichiometry for this reaction is
The rate for this reaction can be written as
![-r_{NO_2}=-\frac{d\left[NO_2\right]}{dt}=\frac{(0.01-0.008)M}{100s}=2\times{10}^{-5}\frac{M}{s}](https://tex.z-dn.net/?f=-r_%7BNO_2%7D%3D-%5Cfrac%7Bd%5Cleft%5BNO_2%5Cright%5D%7D%7Bdt%7D%3D%5Cfrac%7B%280.01-0.008%29M%7D%7B100s%7D%3D2%5Ctimes%7B10%7D%5E%7B-5%7D%5Cfrac%7BM%7D%7Bs%7D)
This rate of disappearence of 
can be realated to the rate of appearence of 
as follows (the coefficients of each compound are defined by the stoichiometry of the reaction)
