Answer:B is an ionic compound
Explanation:This is because when we look at the properties of ionic compounds, we see that the form crystals just like salt(sodium chloride), they dissolve in water, have a high boiling and melting point, are hard due to the strong intermolecular forces between atoms and conduct electricity (only molten or in solution form)
Gravity is the force of attraction between two objects, and Earth's gravity pulls matter downward, toward its center. It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. ... Gravity pulls denser air and water downward, forcing less dense air and water to move upward.

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.
