A protein molecule is a polymer which means it is built when lots of smaller molecules join together in a chain, like building blocks. These smaller molecules are called amino acids. There are are 20 diff...

The trick here is similar to remembering all complicated formulas in science: Assign some meaning to all letters that make some sense, and is easier to remember. Our formula here is pV=nRT, where p-pressu...

All 3 compounds are basic structures in Organic Chemistry, more precise: Aromatic Chemistry, as all of them have a benzene ring (having a benzene in compound is definition of Aromatic compound). That give...

We approach this problem using the conservation of linear momentum, which tells us that m1 x v1 = m2 x v2. We substitute the values of m1, v1 and v2, and solve for m2: 48x1.2=m2x16; m2=57.6/16=3.6 kg.

In 1936 Hans Selye developed his theory of the General Adaptation Syndrome (GAS), which is a stress model that explains the body's physiological response to stress. These stress responses are divided into...
