Answer:

Pulp and Paper technology is a specialist field of chemical engineering which involves the study of the processes required for the conversion of raw materials such as wood, into pulp and paper products.

Paper and pulp manufacturing is a growing and dynamic industry so it requires a wide variety of personnel - from unskilled and semi-skilled workers to tradesmen, technicians and engineers - to control all the processes and develop new ones.

I choose to be a chemist in the field of paper and pulp. Requirements and compulsory Subjects: Physical Sciences, Mathematics, Engiineering and Technology.

Chemists are responsible for quality control and they study the influence of various chemicals on pulp and paper. Chemical and mechanical engineers develop new production methods.

I'll like to be a chemist in the field of paper and pulp because they perform the major role in the chemical properties of the paper and pulp.

Explanation:

Hope it helps.

Water vapor is not usually seen.
xeze [42]

Answer:

True

Explanation:

Water vapor is totally invisible.

Without it, there would be no clouds or rain or snow, since all of these require water vapor in order to form. All of the water vapor that evaporates from the surface of the Earth eventually returns as precipitation - rain or snow.

Identify the oxidizing and reducing agents in the following: H2S(aq) + Cl2(g) -&gt; S(s) + 2HCI (aq)
alexgriva [62]

The oxidizing and reducing agent in the above redox reaction are hydrogen sulphide (H2S) and Chlorine (Cl) respectively.

<h3>What is an oxidizing and reducing agent?</h3>

An oxidizing agent is any substance that oxidizes, or receives electrons from another substance and as a result, becoming reduced.

On the other hand, a reducing agent is any substance that reduces or donates electrons to another and as a result becomes oxidized.

According to this reaction; H2S(aq) + Cl2(g) -> S(s) + 2HCI (aq)

  • H2S accepts electrons from Cl2 and becomes reduced to S
  • Cl2 donates electrons to H2S and becomes oxidized to HCl

Therefore, the oxidizing and reducing agent in the above redox reaction are hydrogen sulphide (H2S) and Chlorine (Cl) respectively.

Describe three characteristics of the outer core and explain why the outer core is so important to humans on earth.
iren2701 [21]

Answer:

The outer core is the only layer that is liquid. It is also mainly made from nickel and iron. The main job of the outer core is that it's responsible for the Earth's magnetic field. As the earth spins, the liquid inside this layer spins aswell, keeping it balanced.

In which phase(s) do the molecules take the shape of the container?
Katen [24]

Answer:

Liquid and gas

Explanation:

Liquid and gas are the phases of matter that take the shape of container.

This is very simple to imagine, if we have a piece of rock and we put it in a container, it will  not take the shape of container as it already has a definite shape and volume. Liquid when put in a container takes the shape of container but varies in volume as per the container.

However, the gas phases is the phase of matter that perfectly takes the shape of container and occupies all the volume of container as well.

If we recall Dalton's Law of Partial Pressures  we can see that the pressure exerted by the gas components in a container is same like the pressure exerted by the gas alone. These partial pressures of the component of gas combine in such a way that they exert total pressure equal to the constituents' pressure on the container. This way gases occupy all the volume of a container and take the shape of a container they're placed in.

Hope it help!

A gas that exerts a pressure of
Semenov [28]

Answer:

3.1L

Explanation: using Boyle's law p1v1=p2v2

p1=15.6,v1=?,p2=25.43,v2=1.895

manipulate the formula to favor so to find v1 the formula would be

p2v2/p1

25.43*1.895\15.6=3.1L
