Answer:
the carbon atoms in the double bond cannot rotate
Explanation:
Isomers refer to molecules that have a distinct arrangement of the atoms in the molecule but have the same molecular formula.
Alkenes refer to a series of unsaturated hydrocarbons that contain ethylene and propylene.
Some alkenes have geometric (cis-trans) isomers because <u>the carbon atoms in the double bond cannot rotate</u>.

Answer:
Double displacement chemical reaction.
Explanation:
Hello,
In this case, for the given reaction we firstly balance it:
Then, since the lithium and potassium cations are being exchanged to each other from bromide and carbonate, we are talking about a double displacement chemical reaction.
Best regards.
Answer:
CaCl2 (aq) + K2CO3(aq) ---------> CaCO3(s) + 2KCl(aq)
Explanation:
We have the reactants as calcium chloride and potassium carbonate. Recall that we are expecting that the reaction will yield a precipitate. We must keep that in mind as we seek to write its balanced chemical reaction equation.
So we now have;
CaCl2 (aq) + K2CO3(aq) ---------> CaCO3(s) + 2KCl(aq)
Recall that the rule of balancing chemical reaction equation states that the number of atoms of each element on the right side of the reaction equation must be the same as the number of atoms of the same element on the left hand side of the reaction equation.
