Water
Water is the most abundant compound in the vast majority of cells. It forms about 60 to 90% of the total chemical content of the cell. Water accounts for about 65% of the chemical composition in the human body. In a jellyfish, the water content in the body is more t..

Molecules having three bond pairs and one lone pair
> molecule, the bond pairs are pushed slightly inwards due to greater lone pair- bond pair repulsions. Thus, the ideal bond angle of 10928' for a tetrahedral arrangement in such molecules is lower, the actual HPH angle, being 104 o . Thus, PH 3 is a trigonal pyramidal ..

Tutors are AMAZING, and They helped me understand every single part of the problem and because of the way they explained everything, i had no questions to ask. It was a learning experience to remember. :)
This tutor is very good. Tutor help you to understand the concept of the problem rather than just complete the problem.
Hard work will pay im confident to go ahead and focus on my studies with help of Tutor Vista
very patient tutor, explained everything step by step did not loose patience when i was not understanding and did not give up till i understood, 5 star i give coz she rocks.Highly recommend Tutor Vista
