Answer: Correct.
Explanation: Propene reacts with bromine and add two bromine atoms give the 1,2-dibromopropane. Two bromine atoms are added to the double bond carbon. Ethene was a non polar alkene. But propene is a polar molecule. This reaction is also an electrophilic addition reaction.
Answer:
Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).
Answer: AIP
There are two types of substances mixture and pure substance. Mixture has NO chemical formula and a pure substance has a chemical formula. There are two types of pure substances, elements (mono atomic and molecular) and compounds ( covalent and ionic).
Ionic compounds do not exist in independent molecular form. They form three dimensional crystal lattice, in which each ion is surrounded by oppositely charged ion. so the ratio of ion is called the formula unit
The number of students is your independent variable
