The elements can be classified as metals, nonmetals, or metalloids. Metals are good conductors of heat and electricity, and are malleable (they can be hammered into sheets) and ductile (they can be drawn into wire). How many types of elements are? At present, 118 elements are known to us. All these have different properties. Out […]
What is KH in chemistry equilibrium? Kh is hydrolysis constant is an equilibrium constant for a hydrolysis reaction. For eg: Al3+ + 2H2O โ AlOH2+ + H3O+ The hydrolysis constant for this reaction is as shown: Kh = [H3O+] * [AlOH2+] / [Al3+] How do you calculate pH in chemistry? To calculate the pH of […]
Becoming an associate professor requires a four-year bachelor’s degree, six years (on average) of doctoral work to get your Ph. D., and an average of seven years as an assistant professor before getting promoted – which amounts to 17 years in total. This time can vary depending on how long it takes to complete your […]
A primary excitatory neurotransmitter in the nervous system is glutamate, and there are several excitatory amino acid (EAA) toxins that can cause seizures. Kainic acid and a similar EAA domoic acid activate NMDA and AMPA subtypes of glutamate receptors, and cause an influx of excessive calcium. How seizures are generated? Seizure initiation is characterized by […]
noun. a number of sheets of paper, formerly 480 sheets (short ream), now 500 sheets (long ream) or 516 sheets (printer’s ream or perfect ream). One ream is equal to 20 quires. (often plural) informal a large quantity, esp of written matterhe wrote reams. How many moles are in A ream? The number 6.02ร1023 is […]
Vaporization Examples The surface of a water puddle evaporates during the day. Water is turned into steam when it comes to boiling. What is the vaporization in chemistry? vaporization, conversion of a substance from the liquid or solid phase into the gaseous (vapour) phase. If conditions allow the formation of vapour bubbles within a liquid, […]
In general, a good private organic chemistry tutor will have a good grasp of math and science topics. They may have experience as a teaching assistant in graduate school or a bachelor’s degree in organic chemistry. Who is the owner of Organic Chemistry tutor? Julio Gonzales, better known online as The Organic Chemistry Tutor, is […]
Medicinal chemistry plays an important role in teaching pharmacy students critical thinking and evidence-based problem-solving skills, allowing them to make the best patient-specific treatment decisions possible.

HISTORY OF CHEMISTRY. The Greek philosopher Empedocles, a native of Sicily, introduces a theory which will be accepted in Europe until the 17th century. He states that all matter is made up, in differing proportions, of four elemental substances – earth, air, fire and water. How did Greece contribute to science? It was the Greeks […]
The value of E indicates the willingness of a half-cell to be reduced (i.e. it is a reduction potential). It shows the how many volts are required to make the system undergo the specified reduction, compared to a standard hydrogen half-cell, whose standard electrode potential is defined as 0.00 V. How is E standard calculated? […]
