Biochemistry is becoming more and more important in pharmacy. Biopharmaceuticals are methods that use biological organisms to produce drugs. Biopharmaceuticals are manufactured using the principles and methods of microbiology, chemistry, biochemistry, biotechnology, and pharmacy. A class of drugs used to prevent, treat, and diagnose diseases. For example, ox bile extract (Ox … Read more
Chain-growth polymerization or chain polymerization is a polymerization technique where unsaturated monomer molecules add onto the active site of a growing polymer chain one at a time. Growth of the polymer occurs only at one (or possibly more) ends. Addition of each monomer unit regenerates the active site. Pls visit@ www.iiscm.org/
can any body tell me why we not live without oxgen.
Nowadays, college diplomas are very important in the society. Big companies require to see the diplomas before they hire someone. The college diplomas are regarded as the proof of capability . No college diplomas, no good job. In the official department, everyone needs to get a diploma. How to buy it online? We can help … Read more
Chemistry is really most important for health care services as it is because of chemistry all the medicines are made
Modern glass is made by melting together several minerals at very high temperatures. Silica in the form of sand is the main ingredient and this is combined with soda ash and limestone and melted in a furnace at temperatures of 1700°C. Other materials can be added to produce different colors or properties.
The crust is made up of much lighter rock containing many elements, particularly oxygen and silicon, as well as aluminum, iron, calcium, sodium, potassium and magnesium, in order of their abundance. Oxygen and silicon, both nonmetallic elements, make up about three fourths of the total crust by weight and 93 percent by volume. Then there … Read more
To go from grams to atoms you first need to convert to moles. To convert to moles you divide the number of grams by the molar mass of calcium which is about 12. So dividing 12 by 12 gives you 1. So you have 1 mole of calcium. Then you convert to atoms by multiplying … Read more
If the water not agitated it would take a while to dissolve.
What shift of laser?
As I recall, a photon has no mass, and energy equals kilogram-meters squared per second squared. If the photon has no mass, then the energy must equal zero.

Yes, very important.
Polymer chemistry has contributed to clothing technology by providing man-made polymers to replicate or replace natural polymers such as silk, cotton, wool, etc. Dr. Wallace Hume Carothers (et al.) invented most of the synthetic polymers used in clothing today, including neoprene (wet suits), nylon (panty hose), and polyester (you name it), while working for DuPont … Read more
Just look around you, metals and nonmetals are all around.
Glucose is the simplest form of carbohydrate i.e. Energy. In a healthy body, after eating, food breaks down into smaller form in order to release energy. But in unhealthy body especially patients, this breakage process gets slower as digestion affected due to illness
Since many inorganic compounds contain some type of metal (alkali, alkaline, transition, etc.), they tend to be able to conduct electricity. For example, while in the solid state, inorganic compounds are poor conductors of electricity. However, in the liquid phase, inorganic compounds are highly conductive. In this phase, inorganic compounds' electrons are able to move … Read more
The radius of a single atom of a generic element X is 187 picometers (pm) and a crystal of X has a unit cell that is a simple cubic. Calculate the volume of the unit cell.
According me water has higher freezing point and lower boiling point than other thermometric liquids.
