Answer:
when the velocity of an object changes,it is acted upon by an external force
Answer:
The correct answer is "All chemical reactions occur at different rates".
Explanation:
The reaction speed is given by the amount of substance that is transformed into a given reaction per unit volume and time. Several factors influence the speed of a chemical reaction. One of them is the concentration of the reagents and the other the temperature, as well as the pressure.
Have a nice day!
Answer:
monochlorinated products: 4
dichlorinated products: 12
Explanation:
Chlorination of alkanes is a reaction that takes place when the chlorine is in presence of light. This actually decomposes the chlorine, and one atom of Chlorine substracts an hydrogen from the alkane. Now, this hydrogen substracted comes usually from the most substitued carbon, because it's more stable (A tertiary carbon is more stable than a secondary carbon, and this more stable than primary).
When this happens, the other chlorine atom, goes as electrophyle in that carbon and formed the chlorinated product. Now, although a tertiary carbon is more stable, we can still have (in minor quantities) chlorinated products that comes from a secondary and primary carbon. The first picture shows the general mechanism of the chlorination, and the possible products for a monochlorinated.
The second picture shows the possible dichlorinated products, which are in higher quantities than the monochlorinated basicallu because of the variety of positions the chlorine can be. So, second picture shows all the products.
Answer:
atoms. For every one mole of Aspartame there are 18 moles of hydrogen
The structure of isocynide is
N=C
What is the importance of VSEPR theory?
Valence bond theory describes the electronic structure of molecule .The theory says that electrons fills the atomic orbitals of an atom within a molecule .
In the structure of isocynide there are triple bonds between Nitrogen and carbon . The bond length is 115.8pm and the bond angle is 180°. There is two pi and one sigma bond .
