We have period 2 group 7, period 2 group 8, and period 1 group 8 elements. So lets go back to our definition. The ability for an atom to attract a pair of bonding electrons By looking at this …

Each element has their own charge, based on the periodic table When we talk about elements, we really want to know what an atom is. We normally think of electrons on the outside and a …

Ionic compounds do not actually satisfy the octet rule. The octet rule is that atoms of elements are most stable when the valence shell of s^2 and p^6 are filled with eight electrons, making the …

Feb 18, 2018 · The functional theories of grammar are different approaches to the study of language and its elements to understand linguistic structures and processes. With these …

44.009 "amu" To calculate the mass of one individual molecule of "CO"_2, we need to Multiply the atomic mass of carbon by however many carbon atoms are in the compound (1) Multiply the …

A block weighing #6 kg# is on a plane with an incline of # (5pi)/6# and friction coefficient of #4/5#. How much force, if any, is necessary to keep the block from sliding down?

I'd say 99. In fact, a periodic number like 0.abcabcabc... is given by the fraction {abc}/999, and in general such periodic numbers are given by the fraction with the repeating block at the …

Well,here we can apply that amount of force which is necessary just to balance the frictional force,and i.e obviously equals to the magnitude of the frictional force,so that the block will …

Read below. We have: f (x)= (x+xcos (x))/ (x-xcos (x)) We can simplify this by factoring: f (x)= (x (1+cos (x)))/ (x (1-cos (x)) We can cross out the x's. f (x)= (1+cos (x))/ (1-cos (x)) Now, a …

f' (x)= (x-3)/|x-3| f (x)=|x-3| Since |x|=sqrt (x^2), we can rewrite as f (x)=sqrt ( (x-3)^2). Use the chain rule dy/dx=dy/ (du)* (du)/ (dv)* (dv)/dx where y=sqrt ...
