The changes that cannot be reversed is known as chemical changes. For ex: Convertion of milk into curd,rusting of iron,etc.

The changes that can be easily reverse is known as physical changes. For ex: Evaporation, freezing of water,etc.

Dilute acid is one which contains much more of water in it. It is obtained by mixing the concentrated acid with water. The process of mixing concentrated acid with water is highly exothermic reaction. So, when a concentrated acid and water are mixed together, a high amount of heat is involved.

IF the system is released from a horizontal position,what is the angular velocity w of the rod when it becomes vertical?

World-agriculture-70% & in industry-25%& domastic use-5%& in India-90%.

For naming problems, give the IUPAC name. For reaction problems, complete the reactions by drawing skeletal structures and mechanisms if needed. For everything else, read the instructions and answer. All work should be done on paper using pen or pencil.

clearly , isomerism means same formula but different structue

Im in need of help with Organic Chemistry. I uploaded a practice exam that Im needing help with. I need you to really know Organic Chemistry, as Ill be needing help all month.

18.02 g/mol, calculated as (21.008)+16.00=18.01618.02(2 times 1.008) + 16.00 = 18.016 approx 18.02(21.008)+16.00=18.01618.02.
