Answer: The energy of an electron depends on its location with respect to the nucleus of an atom. The higher the energy of an electron in an atom, the farther is its most probable location from the nucleus.
Answer:
To convert a decimal into scientific notation, move the decimal point until you get to the left of the first non-zero integer. The number of places the decimal point moves is the power of the exponent, because each movement represents a "power of 10".
The solution for this problem is:
C6H5NH3Cl is a strong salt: C6H5NH3+ + Cl- C6H5NH3+ + H2O <-----> C6H5NH2 + H3O+
K = Kw/ Kb= 1.0 x 10^-14 / 3.8 x 10^-10= 2.6 x 10^-5
=2.6 x 10^-5 = x^2 / 0.240-x
x = [H3O+] = 0.00251 M
pH = 2.60 is the concentration
Na2CO3 Na= 23*2=46 C=12 O=16*3=48. Na2CO3=106. 46/106*0.175=0=403
The empirical formula of the compound is C₄H₅O₃.
<u>Explanation</u>:
If hydrogen % = 5.98823, the Sum of C+O = 94.01177% or 47.005885% each
The original mass of 300 g is not important
C = 47.005885 / 12.011 = 3.913569
H = 5.98823 / 1.008 = 5.94070
O = 47.005885 / 15.999 = 2.93805
Divide by the smallest number:
C =1.33
H = 2.022
O = 1
Multiply through by 3
C = 4
H =6
O = 3
The empirical formula of a compound = C₄H₆O₃
Do not be confused by the 300 g. It is totally irrelevant to the question because you are dealing with % amounts. It would only have been of importance if you were given some mass values.
