The arrows in the image show the direction in which carbon is moving Which process of the carbon cycle is indicated

1 answer:

8 0

The carbon cycle involves the circulation of carbon dioxide (CO2) from the atmosphere into plants and other living organisms; the transfer of carbon from these organisms into other temporary storage pools, living or nonliving, containing organic and inorganic carbon compounds; and the return of CO2 to the atmosphere

Study the graph in Figure 6.32 and answer to these questions. (see attached image)

Hey there :)

We can see that the solubility of salt increases with increasing temperature. This happens with most substances.

To find out the maximum mass of copper sulfate that can be dissolved in water at these temperatures, just interpret the graph.

Considering Y-axis as g copper sulfate/100 g water and the X-axis as the temperature in °C:-

1)

a: 0 °C - 14 g of copper sulfate/100 g of water

b: 50 °C - 34 g of copper sulfate/100 g of water

c: 90 °C - 66 g of copper sulfate/100 g of water

2) From the graph, we can infer that temperature affects the solubility of the salt.

Compare the polymerisation reaction used to produce poly(ethene) with the

butalik [34]

Answer:

See explanation

Explanation:

Polymerization is the process whereby two or more monomers link together to form a compound of high molecular mass called a polymer.

There are two kinds of polymers;

-Addition polymers

-Condensation polymers

Addition polymers are formed by the joining of two or more monomers to form a polymer without the elimination of a small molecule.

Condensation polymers are formed by the joining of two or more molecules to form polymers with the elimination of a small molecule.

The main difference between polyethene and polyester is that polyethene is an addition polymer while polyester is a condensation polymer.

In polyethene, ethene molecules are joined together having the repeating unit as [-CH2-CH2-]n.

In polyester, the polymer arises from the reaction of carboxylic acid and an alcohol and loss of water molecules.
