Physical Properties: Sodium bicarbonate is an odorless, white crystalline solid or fine powder. It has a slightly alkaline taste. Its density is 2.20 g mL-1 and it decomposes in temperatures above 50 ºC. The decomposition yields to sodium carbonate. It is highly soluble in water and poorly soluble in acetone and methanol. It is insoluble in ethanol.
Chemical Properties: Sodium bicarbonate is an amphoteric compounds, it means the compound has a character acids an basic at the same time. It is highly soluble in water, resulting in a slighty alkaline solution.
i hope this part helps i will continue to research on Toothpaste's properties
We have to discuss here whether mole should be considered as a base unit in SI system or not.
The answer is- mole is considered as base unit in SI system.
There are seven base units in the SI system. They are- kilogram (kg) for mass, second (s) for time, kelvin (K) for temperature, ampere (A) for electric current, mole (mol) for the amount of substance, candela (cd) for luminous intensity and meter (m) is for distance.
Mole is defined as the amount of substance that contains as many elementary entities as there are atoms in 0.012 kilogram of carbon-12. One mole contains exactly 6.022 X 10²³ elementary entities.
This number 6.022 X 10²³ is the fixed numerical value which is called Avogadro number which is universally accepted number. Hence mole is also base unit in the SI system.
Their is 2 valence electrons
Gasoline and motor oil are chemically similar. They are both mixtures of nonpolar hydrocarbons containing carbon and hydrogen atoms. However, motor oil is much more viscous Motor Oil
A chef is using honey in a recipe. The honey is too thick to pour out of the jar. How could the chef make the honey easier to pour? heat it
Water’s molar mass is 18.01 g/mol. The molar mass of methanol is 32.01 g/mol. At room temperature, water is 64% more viscous than methanol. Which substance has the stronger intermolecular attraction? water
Answer:
2D structure is based on skeletal formula and
3D structure is based on ball and rod model
Explanation:
Please find the attached image of 2 D and 3 D structure of cis-4-nonene
The 2D structure of Cis-4 nonene resembles the shape of skeletal formula. Almost every organic molecule has notation of skeletal formula. Each carbon atom is connected to sufficient number of hydrogen atom so that the valence of each carbon atom is satisfied.
The carbon atom is located at the corner while the hydrogen atom are not indicated.
The three dimensional structure of Cis-4 nonene is based on stick and ball model where ball represents the various types of atoms and the rod length represents the bond. White ball represents the hydrogen atom and grey ball represents the carbon atoms.
