question 1 of 3 Which of the following choices is expressed by pKa? The equilibrium constant of an acid The equilibrium constant of a base The magnitude of the strength of an acid The magnitude of the strength of a base Next Worksheet 1. Which of the following wo...
In contrast, the surface atoms will have an incomplete, unbalanced set of interactions, and therefore have unrealised bonding energy. Surface energy is a relative measurement of the energy at the surface (which is a result of this incomplete bonding). It is positively correlated to the strength ...
torque is the expression of a rotational or twisting force. the engines in vehicles rotate about an axis, thus creating torque. it can be viewed as the strength of a vehicle. torque is what rockets a sports car from 0-60 kmph in seconds. torque is also what powers big trucks hauling...
As shown by the equation for the ionization constant, - the formula characterizes acid dissociation in terms of the relationship between an acid and its conjugate base. Based on this relationship, the {eq}K_a {/eq} value can be used to estimate the strength of the acid and its conjugate ...
