Compounds whose heats of formation cannot be measured directly using calorimetric methods because they cannot be synthesised from their elements easily e.g. methane, carbon monoxide, benzene etc are determined using Hess's Law. For example, the heat of formation of carbon monox..

The emission of a or b - particles from a radioactive element results in the function of new element called daughter element. If the daughter element still has unstable nucleus, it further disintegrates by emitting a or b - particle and produces a new daughter element. This process of..

If the daughter element still has unstable nucleus, it further disintegrates by emitting a or b - particle and produces a new daughter element. This process of successive di..

Nitrogen atom has five electrons in its valence shell. Thus, it requires three more electrons to acquire a stable configuration of the nearest noble gas (neon). This is done by mutually sharing three pairs of electrons as shown below: ..

The electronic configurations of carbon and oxygen are, Thus, each carbon atom requires four, and each oxygen atom requires two more electrons to acquire noble gas configurations. This is achieved as follows: ..

In 1970, there were less than 50 software companies in Smart City Software Park. The number of these software companies has changed over the years. Construct a time series graph for the data and comment on the findings. Year Software companies 1992 69 1993 79 1994 103 1995 112 1..

Modems - The 'modem' is a contraction of the term modulator-demodulator. It is a conversion that facilitates the transmission and reception of the data over the public switched telephone network (PSTN). The data of interest may be digital signals generated by computers or servic..

The damaged platelets release a substance called thromboplastin. This sets in action, a series of reactions that result in the formation of clots. These clots block the site of the injury, avoiding excess loss of bloo..

1. The mean deviation (M.D) of a statistical data is defined as the arithmetic mean of the numerical values of the deviations of the items from some average. 2. The standard deviation of a statistical data is defined as the positive square root of the A.M of the squa..
