<em>Reasons why a 100% yield is not obtained in actual chemical manufacturing processes may be;</em>

- The reactor has a certain capacity to produce a certain yield  

- There is a limiting reactant that runs out and the reaction can not proceed any further

It may also be because the reaction is reversible or because of loses of desired product during isolation and purification.

What is the capillary rise of ethanol in a glass tube with a 0.1 mm radius if the surface tension of ethanol is 0.032Jm2 and the
iragen [17]

Answer:

Explanation:

Expression for capillary rise is as follows

h = 2T / ρ g r where T is surface tension , ρ is density of liquid and r is radius of capillary tube.

T = .032 J m⁻²

ρ = .71 g / cm³

= 7100 kg / m³

r = .1 x 10⁻³ m = 10⁻⁴ m

h = 2 x .032 / (7100 x 9.8 x 10⁻⁴ )

h = .0092 m

= 9.2 mm .

Astronomers studying the planet of Rhombus have detected sedimentary rock on its surface. One astronomer wonders if material in
Fed [463]

Answer:

igneous rock CAN become sedimentary rock through a process called ROCK CYCLE.

Explanation:

Rocks can be defined as solid structures of minerals that are formed naturally over a period of time. They are grouped into three main types which includes the following:

- igneous rock

- sedimentary rocks and

- metamorphic rocks.

Rocks are capable of transforming from one type to another through a process known as rock cycle. There are two forces that brings about this process which includes:

- The internal force : this is the Earth’s internal heat engine, which moves material around in the core and the mantle and leads to slow but significant changes within the crust.

- The external force: this is the the hydrological cycle, which is the movement of water, ice, and air at the surface, and is powered by the sun.

Molten magma cools to form either extrusive igneous rock or intrusive igneous rock. With time they undergo weathering, eroded, transported, and then deposited as sediments which are being compressed and cemented into SEDIMENTARY ROCKS. Again through the above mentioned forces, different kinds of rocks are either uplifted, to be re-eroded, or buried deeper within the crust where they are heated up, squeezed, and changed into METAMORPHIC ROCK.

Therefore the material in this sedimentary rock found in Rhombus planet used to be in igneous rock deep in Rhombus's interior due to continuous rock cycling on the planet. I hope this helps, thanks.

Write out the recipe and list all the ingredients (including the measures) of your favorite dish.
arsen [322]

The recipe for an omelet are:

<u>Ingredients</u>

  • 1 Egg
  • Salt and pepper ( 1 tablespoon )
  • Butter ( 1 tablespoon )

<u>Recipe:</u>

  • Turn on the heat and place a pan on it.
  • Add butter to the pan.
  • Crack the egg and whisk it properly.
  • Add the whisked omelet onto the pan and stir.
  • Add salt and pepper.

<h3>How to illustrate the information?</h3>

When we turn on the heat and place the pan, a heat transfer takes place and heat transfers from one body to another.

When we add butter to the pan, then the temperature of the pan was more than that of the butter.

Since the melting point of butter was less than the temperature of the pan, the the melting of butter takes place.

When we add the egg, the evaporation of the liquid present in the egg yolk and the egg white takes place.

These are the chemical reactions depicted.
