Catalytic oxidation of SO 2 to SO 3 . Catalyst - V 2 O 5 (Vanadium pentoxide) or platinum Temperature: 450 o C - 500 o C. Pressure: 760 - 1520 mm of Hg..

The oxidation number of zinc has increased from 0 to +2 while that of hydrogen has decreased from +1 to 0. However, the oxidation number of chlorine remains same on both sides of the equation. Therefore, zinc is reducing agent while HCl is oxidizing agent in reaction and the ch..

Find the squares of these deviations i.e., x 2 and obtain the sum of the square of deviation i.e..

Balance the increase/decrease in oxidation number by multiplying NO 3 - by 2 and Cu by 0..

Since both the condition are satisfied, Mean Value Theorem is applicable. \ There exist c (4, 10) such that \ f (4) = 0 f '(c) = 3c 2 - 36c + 104 Substituting these values in (1), we have ..

An equation is called a Linear equation in one variable or an equation of degree one in one variable, if only a single variable with degree one occurs in the equation. An equation is called a Linear equation i..

Which of the following is a linear inequality with two variables? => 2 x + 6 y = 0 or x + 6 = 0 or 8 x + 1 ≤ 6 or 6 x + 2 y ≥ 6..

Variable Valency - Normally metals donate electrons from their valence shell so as to form positively charged ions such that the charge on the ion is equal to its electropositive valency. However, in transition elements, an atom loses electrons from the shell next to the valence shell (pe..

Consider an example. A person was asked to measure the thickness of a coin. He recorded the following readings: (i) 0.2 cm with ruler (ii) 0.23 cm with vernier (iii) 0.231 cm with micrometer The accuracy of thickness of the coin depended on the instrument used for measuring the thickness..

The position of a point in a plane is fixed by selecting two axes of reference which are formed by combining two number lines at right angles so that their zeros coincide. The horizontal number line is called x-axis and the vertical number line is called y-axi..
