Answer:
MgF₂
Explanation:
Fluorine only has a 1- charge, so to satisfy the 2+ charge on magnesium–– you need 2 fluorine atoms to balance out the charges.
In an endothermic reaction products are <u>HIGHER </u>than reactants in potential energy and <u>LESS </u>stable.
Explanation:
Energy is input into the reaction in an endothermic reaction. This means the products are of a higher energy level than the reactants. Therefore the reaction increases Gibb's free energy and reduces entropy. Remember in thermodynamic stability involves an increase in entropy and a decrease in Gibbs free energy. Therefore the products are less stable than the reactants. This is why endothermic reactions do not occur spontaneously like exothermic reactions.
The answer is C, the particles collide more and have more energy
One of the hydrogens in the NH3 is replaced in the first reaction by the methyl group, or -CH3. The NH3 can have more than one H substituted for it, therefore the final product frequently comprises a blend of methylamine, dimethylamine, and trimethylamine.
A halogenoalkane and ethanolic ammonia can be used in a nucleophilic substitution process to produce primary aliphatic amines like methylamine (CH3NH2).
NH3 + CH3Cl = HCl + CH3NH2
The process is challenging because any unreacted ammonia can react with the generated HCl:
NH3+HCl yields NH4Cl.
Since the N in CH3NH2 still has a single pair of electrons, it can act as a base and interact with the HCl that is created in one of the following ways:
CH3NH2+HCl becomes CH3NH3+Cl.
or as a nucleophile and react with any chloromethane that hasn't been reacted:
(CH3)2NH + HCl = CH3NH2 + CH3Cl
