ideal and real stoichiometric calculations

Ideal and Real Gases - An ideal gas is one, which obeys the general gas equation of PV = nRT and other gas laws at all temperatures and pressures. A real gas, does not obey the general gas equation and other gas laws at all conditions of temperature and press..

Most chemical reactions are carried out in solutions. It is therefore important to know how to express the concentration of the substance in its solutio..

If an imperfection causes the ratio of cations to anions to become different from that indicated by the ideal chemical formula, the defect is called non-stoichiometric..

If an imperfection causes the ratio of cations to anions to become different from that indicated by the ideal chemical formula, the defect is called non-stoichiometric. There are three types: Metal excess Metal deficiency Impurity defect..

). This means that 'K' is directly proportional to the number of moles, 'n', i.e., K n or K = nR, where 'R' is the universal gas constant of proportionality. The value of 'R' is same for all gases. However, the numerical value of 'R' varies with the units in which pressure and volume are expressed...

. In chemical calculations, volumes are often expressed in litres (L) and pressures in atmospheres (atm) in this system, to four significant digits, We can express the ideal gas equation, equation (3), in terms of the mass m t o t of gas, using m t o t =nM from equation (2): ---..

Calculate the value of m if 25 x 2 + m x + 36 = 0 has one real solution. =>± 60 or 0 or 62 or none of the above..

Which of the following represents the graph of f ( x ) = 3 x 3 -11 x + 5 and its non integral real zeros to the nearest tenth? [Use a graphing calculator.] => Figure 2; real zeros of f ( x ) are - 1.6, - 0.5 and 2.1 or Figure 1; real zeros of f ( x ) are - 2...

Which of the following represents the graph of f ( x ) = 4 x 3 - 4 x 2 - x + 1 and its real zeros to the nearest half unit?[Use a graphing calculator.] => Figure 1; real zeros of f ( x ) are - 0.5, 0.5 and 1.0 or Figure 2; real zeros of f ( x ) are - 1.0, - 0..
