See explanation below
Explanation:
The malonic ester synthesis is a commonly used reaction to form several products. In this case when we have an excess of base, in presence of an alkyl halide of 4 carbons, this will promoves the formation of a ring.
This synthesis has 4 steps:
1) Enolate formation. In this step the strong base (Such as methoxyde) will substracts the more acidic atom of hydrogen in the molecule. In the malonic ester, it would be the hydrogens from carbon 2.
2) Enolate alkylation. Once the enolate has been formed in the previous step, it will become a nucleophyle, and will attack the alkyl halide to form an enolate alkyl. Then, as we have excess of base, we are going back to step 1 to substract the remaining hydrogen, and then, step 2 again so the remaining bromine leaves the molecule. In this part, it will form the ring.
3) Ester hydrolisis. When the ring is formed, it's time to do an hydrolisis of the ester, so we can convert the ester into carboxilic acids. As we have two ester,we will have two carboxilic acids.
4) Decarboxilation. Finally, a decarboxilation occurs in presence of heat to have the final product with a ring and CO2 there as final products.

I know for a fact the answer would (not) be the last option. This would not be a way that electricity would be able to really flow.
Your correct answer would be of when the
"e<span>
lectrons flow from the negative end of a source towards the positive end."This would be because when the electrons would be free, they would have enough energy to then move from the negative side of the end, to the positive side.</span>
Answer:
a metal
Explanation:
metals are good conductors of electricity
Rutherford's gold foil experiment proved that there was a small, dense, positively charged nucleus at the center, which contained most of the mass of the atom. Which contained electrons orbiting the nucleus.
