Answer:

Sand - A network

Dry Ice - Molecule

Lime - Ionic

Gold bar - Metallic

Explanation:

The items are;

dry ice (CO2)

lime (CaO)

gold bar (Au)

sand (SiO2)

The options are;

molecular,

an ionic,

a network,

or a metallic solid

Among the items, the only metal present is the gold bar. So it makes sense that the gold bar is matched with 'Metallic solid'.

The Calcium oxide is an 'ionic' compound as it contains the calcium ion and the oxygen ion bonded by an electrovalent bond.

Dry Ice, CO2 is a molecule composed of one carbon atom bonded to two oxygen atoms via two double bonds. So it is matched with 'Molecular'

The only option left is 'A network' and it is matched with Sand (SiO2).

The result is given as;

Sand - A network

Dry Ice - Molecule

Lime - Ionic

Gold bar - Metallic

4. Synthesis problems. Propose a synthetic route from the starting material to the product. In your answer, show each individual
Troyanec [42]

The reduction of alkyne to an alkene in the first step allows the best reagent to be chosen for each subsequent step.

Describe reagents.

A reagent is merely an essential component of a chemical reaction, it should be mentioned. It is an ingredient that speeds up the reaction.

With H2 and Lindlar's catalyst, an alkyne is reduced to alkene as the initial step in this process. Alkene will then be brominated to produce allyl bromide as the next step.

In this instance, the required allyl alcohol will be produced via the reaction of allyl bromide with NaOH.

Explain how energy can be absorbed in a chemical reaction
bonufazy [111]

Answer:

Energy is used to break bonds in reactants, and energy is released when new bonds form in products. ... In other chemical reactions, it takes more energy to break bonds in reactants than is released when bonds form in products. These reactions, called endothermic reactions, absorb energy.
