Answer:

The correct option is;

They can be produced at low cost

Explanation:

In comparison to several other manufacturing materials, some synthetic polymers such as plastics are more durable cost effective, flexible, faster to produce and  reliable

With regards to the cost comparison, the resins used for plastic are cheaper to obtain than mining for materials such as metals. In all quantities, it is cheaper to produce and manufacture plastics than to produce metals.

Due to the light weight and corrosion resistance of plastics, it is cheaper to store and transport plastics to several locations with different environment without the plastic requiring much effort for transportation or being affected by corrosion.

Write balanced chemical equations for the sequence of reactions that oxalic acid can undergo when it's dissolved in water.
Mashcka [7]

Answer and Explanation:

The balanced chemical equations are as follows:

The chemical formula of oxalic is  H_2C_2O_4

In the case when oxalic acts reacted with the water so here the oxalic acid eliminates one proton that leads to the development of mono acids

After that, the second step derives that when oxalic acid is in aqueous solution eliminates other proton so it represent the polyprotic acid

Now the chemical equations are as follows:

Elimination of one proton

H_2C_2O_4(aq)+H_2O(l)  \rightarrow H_2C_2O_4^-(aq) + H_3O^+(aq)

Now the elimination of other proton

HC_2O_4^-(aq)+H_2O(l)  \rightarrow C_2O_4^2^-(aq) + H_3O^+(aq)

A particular solution of NaOH has hydronium concentration of 4x10-9 M. what is the solution’s pH?
bearhunter [10]

Answer:

The pH of the solution is 8, 40-

Explanation:

The pH indicates the acidity or basicity of a substance. PH values between 0 and less than 7 indicate acidic solutions, 7 neutral and greater than 7 to 14 basic. It is calculated as

pH = -log (H30+)

pH= -log (4x10-9M)

<em>pH=8,40</em>
