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.
Answer: For the given reaction an increase in the forward reaction rate due to increase in the number of effective collisions.
Explanation:
According to the rate law, rate of a reaction depends on the concentration of its reactants. So, more is the number of reactants then more will be the number of collisions taking place.
As a result, more will be the amount of product formed. For example, in the reaction 
an increase in 
means an increase in the number of reactants.
Hence, more is the number of collisions taking place leading to more amount of formation of products.
Thus, we can conclude that for the given reaction an increase in the forward reaction rate due to increase in the number of effective collisions.
rate 1 of the reaction = k [A]²
rate 2 of the reaction = k [A/2]² = k[A]² /4
We can see that rate of the reaction will be 4 times less.
Answer:
The new pressure will be
1000 L, rounded to one significant figure.
Explanation:
Boyle's law states that when a gas is held at a constant temperature and mass in a closed container, the volume and pressure vary inversely. The equation to use is p1v1=p2v2
