solving one step equations

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..

Use the assumption p(r) is true, to prove p(r+1) is true. ..

The value of n is obtained through the relation,..

For the third term, take coefficient as increase the power of x by 1. Thus, the third term is Repeat this process repeatedl..

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 ..

Formation of solid sodium chloride from Na + ( g ) and Cl - ( g ) . In this step, energy equal to the lattice energy is released. Total energy released per mole of NaCl formed = 776+349.4 kJ= 1125.4 kJ Total energy absorbed in step (1) = 495.8 kJ Therefore, N..

We have the following conditions on the variables x and y. a) Sum of the numbers is atleast 15 i.e., x + y 15 b) Difference of the numbers is at most 7 i.e., x - y 7 c) Since the x and y should be positive, we have two more conditions x > 0, y > 0 We call Z as objective function and the l..

Andy wanted to find the area of the large rectangle ABEF. She used distributive property to solve the area of the rectangle ABEF. Which of the methods shows Andy′s steps? => Method 1 or Method 2 or Method 4 or Method 3..

The earth when it was formed about 4.8 billion years ago, was a hot revolving ball of gas consisting of atoms of various elements. Heavy elements such as iron and nickel were found in the center while comparatively lighter ones like those of aluminium and silicon formed the middle layer. ..
