There are 2 ideas that need to be included here :The concentration of acid decreases over time So collisions are less frequentAs the reaction proceeds more and more molecules would have collided successfu...

In pure metals the atoms are all the same size , hence the layers of atoms can slider over each other. However, in an alloy the different size atoms distory the layers in the structure hence it is difficu...

Calculate the moles of each of the 3 elements (to get C=3.03, H=6, F=3.03). Divide these by the smallest mol calculated to get the ratio of the elements. This will get C:H:F as 1:1.978:1 = 1:2:1 and so th...

As we go down group I, the ions have larger shells and the distance between the bonding electrons and positive nucleus decreases. This decreases the overall attraction forces between the two in metal latt...

A coordinate bond is a bond formed through the donation of a lone pair of electrons from an atom bonding to another atom which has an empty orbital.The lone pair from one atom is donated to the empty orbi...
