problems involving measurements

. In such irreversible reactions, the reactions occur only in the forward direction. These reactions go to completion and no starting materials are left. However, reversible reactions do not go to completion. When these reactions are performed in closed containers, a stage is reached at which the r..

Suppose X = a - b Let D a and D b be absolute errors in measurements of quantities a and b, values of a and b and D X be maximum error in X. Maximum absolute error in X = Maximum absolute error in a + Maximum absolute error in b From equations (1) and (2) it is evident that, when ..

Let D a and D b be absolute errors in measurement of quantities a and b and D X be maximum possible error in X. ..

Processes Involved in Transport - There are some physical principles and biological processes that explain the transport of materials across the plant body. They are as follo..

It is a physical process that involves the movement of solute particles from the region of their higher concentration to the region of their lower concentratio..

It is a physical process that involves the movement of solute particles from the region of their higher concentration to the region of their lower concentration. Transport of materials within the cell is by diffusion. The entry of carbon dioxide into the stomata is by diffusio..

Equilibrium Involving Physical Changes - Substances exist in three states: solids, liquids and gases. The following types of equilibriums exist in three state..

Photosynthesis has two main reactions: Light reaction Dark reacti..

On hydration silicates and aluminates of calcium get converted to their respective hydrated colloidal gels. At the same time, hydrolysis precipitates calcium hydroxide and aluminium hydroxide. This calcium hydroxide binds calcium silicate particles together. On the other hand, alumi..
