Spectroscopic studies show that li can have electrons in its 1s, 2s, and 2p hartree orbitals, and that zeff(2s) 5 1.28 for the 1s22s1 con guration. estimate the energy of the 2s orbital of li. calculate the average distance of the electron from the nucleus in the 2s orbital of li.

Step-by-step explanation:

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
