lab behavior problems

All gases, irrespective of their chemical composition, obey certain laws that govern the relationship between the volume, temperature and pressure of the gases. A given mass of a gas, under definite conditions of temperature and pressure, occupies a definite volume. When any of the three vari..

Anomalous Behavior of Boron and Resemblance with Silicon - Because of extremely small size of its atom and high electronegativity, boron differs in its properties from other elements of the group. On the other hand, it resembles silicon to some extent due to diagonal relationship. The fol..

Anomalous behavior of Lithium - Lithium displays most of the characteristic properties of group to which it belongs i.e. the alkali metals group (Group 1). However, it differs in many respects from the remaining characteristic properties of the metals of Group 1, due to the following reas..

Like all other first elements of the groups, oxygen also differs from its family members. The anomalous behavior of oxygen is due to its (i) small size (ii) high value of ionization energy and electronegativity (iii) absence of d-orbitals in the valence shell. Some of the important differ..

Lithium displays most of the characteristic properties of group to which it belongs i.e. the alkali metals group (Group 1). However, it differs in many respects from the remaining characteristic properties of the metals of Group 1, due to the following reasons: The size of lithium atom and ion is v..

Stability of a Molecule We have learnt that the electrons in bonding molecular orbitals contribute to attraction between the atoms and thereby help in the formation of bond. On the other hand the electrons in antibonding molecular orbitals contribute to repulsion between the atoms and,..

Because of extremely small size of its atom and high electronegativity, boron differs in its properties from other elements of the group. On the other hand, it resembles silicon to some extent due to diagonal relationship. The following properties illustrate the anomalous behavior of boro..

Which of the following is not true regarding the end behavior of of the given graph? => f ( x ) → - ∞ as x → - ∞ or f ( x ) → - ∞ as x → + ∞ or f ( x ) → + ∞ as x → + ∞ or None of the above..

A college computer lab wants to identify each computer system by a letter followed by a digit. How many different choices are available to choose to give the identities to each computer system? => 36 or 16 or 260 or None of the above..

The lowest temperature in a lab setting is about 2.8 × 10 - 10 o k. Write this number in standard form. => 0.000000000028 or 0.00000000028 or 0.0000000028 or 0.000000028..
