In reversible reactions chemical reactions take place in both the forward and backward directions. For example, the reaction between gaseous hydrogen and iodine vapours to give gaseous hydrogen iodide is a reversible reaction and may be expressed as: In this reaction, the products cannot combine to..

The elements of the third period contain d-orbitals also in addition to s- and p-orbitals. The 3d-orbitals are comparable in energy to the 3s- and 3p-orbitals. These d-orbitals are also involved in the hybridization and they explain the geometries of molecules of elements of third p..
Result involving quotient of 2 observed quantities
= maximum percentage error in a + maximum percentage in b. From equations 3, 4, 5 and 6, it is seen that when the result involves the multiplication or quotient of 2 observed quantities, the maximum possible relative error in the result is equal to the sum of the relat..

very helpful of a complex problem, oh my god I would have never completed this problem with out the tutor. Tutor vista thank u so much.
Tutor is an excellent. I would say this tutor is an asset of Tutor Vista.. Excellent Job!!!!!!!
It's help ful session. I translate my book with him it was great time - William
I need tutoring from tutorvista till th end of my schooling. Tutors are not only experts they are brilliant enough to make a student like me understand the concepts of differentiation and functions.
