Answer:
Br2(l) + 2 KI(aq) → 2 KBr(aq) + I2
Explanation:
In this reaction, the solution will have a slight change in color to a different shade of Brown since Bromine and Iodine solution are both in a different shade of brown. (KI and KBr are both colorless, its the Br2 and I2 that has color)
thanks me later :)
Answer:
The reactión is exothermic
Explanation:
The change in enthalpy follow the next equation:
ΔH = ΔH(products) - ΔH(reactants)
If the products have a lower enthalpy means that ΔH<0; this mean that the reaction gives heat to the environment
Answer:
An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. Ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal. A covalent bond involves a pair of electrons being shared between atoms.
If the totaling of bromine to cis-cinnamic acid uses the
same mechanism or device as the addition to trans-cinnamic acid, addition of
bromine only transpires on the top (syn) and not the bottommost face (anti). Therefore,
bromine added to cis-cinnamic only adds to the same face (syn addition) as a
result producing only threo dibromides.
