When exploring periodic tablewithoxidation numbers, it's essential to consider various aspects and implications. Question #021e1 - Socratic. One way we have of differentiating between various nuclides of the same element is by writing the name of the element followed by a hyphen and the mass number of the nuclide. In your case, you would have zinc-66, a nuclide of zinc that has a mass number equal to 66. Now, an atom's mass number, A, tells you the number of protons, which is given by the atomic number, Z, and neutrons ... Site Map - Electronegativity Questions and Videos | Socratic.
It's important to note that, what is #"electronegativity"#? Question #89780 Is electronegativity quantifiable on an absolute scale? Question #eefa2 How does #"electron gain enthalpy"# evolve with respect to the PeriodicTable?
Building on this, explain electronegativity? and how it can justify why a metal will lose electrons and a nonmetal will gain electrons. Why can you have atomic mass not as a whole number for ... It's because of the whole average of all the isotopes.
Equally important, the reason for this is because an atom can have lots of different isotopes, so the atomic mass calculation will be the average of all those isotopes' masses. Two numbers total 71 and have a difference of 11? Using some linear algebra, you can put two equations representing the above statement to find that one number is 41 and the other is 30. let f_1 = (x+y) and f_2 = (x-y) f_1 = 71 f_2 = 11 f_1 + f_2 = 71 + 11 = 82 f_1 + f_2 = (x+y)+(x-y) = 2x 2x=82 x=82/2 = 41 41+y=71 y=30 ans: x=41, y=30 From another angle, friedel Crafts Acylation - Organic Chemistry II | Socratic.
Friedel Crafts acylation is the acylation of an aromatic ring using a strongly acidic catalyst. Moreover, these reactions are usually done with an acyl chloride or acid anhydride molecule. Answers created by reudhreghs - Socratic. What is the oxidation number of oxygen in peroxides?
How do you determine whether the sequence #1/8, 1/4, 1/2, 1,...# is geometric and if it is, what is the common ratio? Given the specific heat of lead is 0.129 J/g#*#K and that it takes 93.4 J of energy to heat a sample of lead from 22.3°C to 40.°C, how do you find the mass of the lead.? Explanation: Write the equation in standard form: #sqrt3tan^2 x - tan x = 0# #tan x (sqrt3tan x - 1) = 0# Either tan x and # (sqrt3tan x - 1)# must be zero.
tan x = 0 --> x = 0, and #x = pi, and x = 2pi# b. In this context, #sqrt3tan x - 1 = 0# #tan x = 1/sqrt3# Trig table and unit circle give --> #x = pi/6# and #x = pi/6 + pi = (7pi)/6# The co-terminal of # (7pi)/6# is # (-5pi)/6# Answers for # [-pi , pi ... The original cost of the item was $460.24 The question tells you that $57.53 is a small part of some larger number. In fact, $57.53 is exactly 12.5% of some larger number. Or in other words, $57.53 is 12.5% of x (x is "the larger number") You can turn that into a math sentence which is easy to solve. [ $57.53 ] "is" [ 12.5% ] "of" [x] [.
