How does food get digested step by step? The processes […]

Why is Aluminium 27 atomic mass? Aluminium is a monoisotopic element and its atomic weight is determined solely by its isotope 27Al. Al is radioactive with a half-life of 0.705(24) Ma, too short for survival of a detectable amount of primordial isotope. However, 26Al is recognized as a spallation product of argon from cosmic rays. […]

What are three types of compounds? Types of Compounds – Categories – Ionic, Molecular and Acids Most types of compounds fall in to one of three categories called ionic compounds, molecular compounds, or acids.

In the 19th Century, Hermann von Helmholtz estimated this to be 35 […]

What is the advantage of single fixed pulley? Answer: Mechanical advantage of a single fixed real pulley is less than one. Change in the direction of force occurs and to overcome the friction in pulley some work is done. So, the force used to pull the rope at your end will be more than the […]

A right angle triangle is an irregular shape, because although it is a shape that we recognise instantly, it has different length sides and different inside […]

What are the quantifiable properties of matter? They include properties such as color, length, volume, odor, and density. These properties are extensive if they depend on the amount of the substance being used or intensive if they do not depend on the amount of substance being used. What are the common properties of matter? The […]

Why does DMSO give Quintet? I learned that dmso peak in 1H NMR caused by proton exchange. So the peak at 2.5 ppm indicates dmso-d5 not d6. Also the dmso which have more exchanged proton like d4 or others can be shown but it is out of normal range. How do you write DMSO-d6? Deuterated […]
