No. Biodegradation is when something is broken down by living things (like bacteria). Stones can be broken down into smaller stones by weather, and minerals and salts can be leached out of them by water, but stones are not biodegradable.

Flooding velocity in a packed column refers to the minimum gas or liquid velocity at which the column becomes completely filled or "flooded" with the fluid, preventing effective mass transfer. At this point, the flow regime transitions from a more efficient operation to a less efficient one, often leading to reduced separation performance. Understanding flooding velocity is crucial for optimizing the design and operation of packed columns in processes like distillation, absorption, and chemical reactions.

You have to go to an explosives dealer that sells TNT. Yes, they exist. They will ask to see your explosives license before you can buy anything from them--like any business that deals strictly with "the trade," if you're not in the trade they won't even let you buy a Coke out of the vending machine in the office.

An increase in temperature will reduce the density, reduce the viscosity, reduce thermal conductivity, and increase the specific heat capacity.

A decrease in temperature will have the opposite affect.

That is the chemical formula. The name would be iron (III) oxide, or ferric oxide in the old system.

Yes. Carbon is added to iron in steel to make the steel stronger by making it more rigid. The more rigid a metal is, the less malleable it is.

Freezing water of is an example of physical change.

It won't work. The slip rings work in conjunction with the brushes to connect a rotating part of the unit with the stationary part. We need to couple current into and out of the rotor, and without the slip rings for the brushes to ride on, we can't do that, and the motor won't work.

A glass-lined reactor typically consists of a metal vessel, often made of carbon steel or stainless steel, that is coated with a layer of glass. This glass lining provides excellent resistance to corrosion and chemical attack, making it ideal for reactions involving aggressive substances. The glass is usually fused to the metal at high temperatures to create a durable, inert surface that can withstand high pressures and temperatures. The composition of the glass itself often includes silica, alumina, and other oxides to enhance its thermal and chemical stability.

Yes, there is demand for chemical engg. if he is good at thermodynamics. reaction engineering and kinetics and process calculation... a chemical engg without these subject is nothing but a coolie...

A fraction in chemistry is a quantity collected from a sample or batch of a substance during fractional distillation i.e. where a mixture is separated into different parts called fractions. A fraction can be defined as a group of chemicals that have similar boiling points.

Chemical engineers produce a huge variety of products and here are just a small sample of the list that a chemical engineer can produce:

1. Oil and gas products (gasoline, engine oil, organic solvents, etc.)

2. Food

3. Medicine

4. Plastics

5. Metals from ore refining and metallurgy

6. Inorganic solvents

7. ...and so much more!

The list goes on and on but chemical engineers are involved in many facets of society and the products we produce can be found just about anywhere.

It is 1.07 gm/cc for amorphous type..

Basicaly chlorhexidine is an antibacterial used as a disinfectant and other applications. It is also used in disinfectants (disinfection of the skin and hands). Chlorhexidine is often used as an active ingredient in mouthwash designed to reduce dental plaque and oral bacteria.

Chlorhexidine lasts longer in the mouth than other mouthwashes, which is partly why it is to be preferred over other treatments for gums. So that is the reason for chlorhexidine to be used in tootpast and mouthwash.

The raw material used for manufacture of cement are limestone and clay. They are ground to form very fine powder and then converted to slurry. The slurry is baked at very high temperature to form granular mass called kilnker. The kilnker is ground and mixed with powdered gypsum to form cement.

You want a liquid that is not compressible so polar compounds are preferres. For safety, the nontoxic and highly stable silicones are used. They have low vapor pressures and high boiling points so they remain liquid and are quite noncompressible.

This type of thermostat is filled with Alcohol, which responds well to changes in airconditioned space.

JP-8 is a fuel specified by the United States Air Force in MIL-DTL-83133E that boil in the range of 186°C (10% boiling point) to 300°C (final boiling point) using the ASTM D2887 test method. The density of JP-8 ranges from 0.775-0.840 kg/L.
