writing balanced equations

. There are 2 positive charges (in 2H + ) on the left side but there are 3 positive charges (in Al 3 + ) on the right side. Now, to have equal charges on both sides, multiply 2H + by 3 and Al 3 + by 2, so that both sides get 6 positive charges each. Thus, the above equation becomes: Thoug..

Write the skeleton redox reaction. Indicate the oxidation number of atoms in each compound above the symbol of the element. Identify the element or elements, which undergo a change in oxidation number, one whose oxidation number increases (reducing agent) and the other whose oxida..

This balance consists of a beam and two scale pans (shown in figure below), the beam being balanced at its mid point on a knife-edge. The scale pans also hang on knife edges and rest on the base board. When the balance is not in use the beam rests on the beam support...

Balanced Diet - The human body requires various types of nutrients in order to keep the body healthy and fit. These nutrients should be taken appropriately in our diet. The diet that we follow should be balanced. Balanced diet is a diet, which provides all the nutrient..

Two large spheres of masses M are brought near m as shown in the figure. The gravitational attraction between m and M turns the system through an angle measured by the reflected light beam. The force per unit twist is calculated by preliminary experiments. Since F, m, M and the distance between m ..

Rules for Writing Equilibrium Constant Expressions - Expression for the equilibrium constant of a reaction is written in the form of a ratio. The numerator consists of the molar concentration (or partial pressure) terms of the products each raised to a power equal to its stoichiometric co..
