i don't really know what you are trying to say here, but what i think you are saying is what sounds like a more impressive job?? in my opinion, pseudoscience sounds more fancy and interesting. Since not a lot of people really knows what that is, it sparks conversation.

Which of the following molecules would have the strongest London Dispersion Force?
weeeeeb [17]

Answer: D

Explanation:

London forces become stronger as the atom in question becomes larger, and to a smaller degree for large molecules. [4] This is due to the increased polarizability of molecules with larger, more dispersed electron clouds. The polarizability is a measure of ease with which electrons can be redistributed; a large polarizability implies that the electrons are more easily redistributed. This trend is exemplified by the halogens (from smallest to largest: F 2 , Cl2 , Br 2 , I 2 ). The same increase of dispersive attraction occurs within and between organic molecules in the order RF<RCL<RBr<RI, or with other more polarizable heteroatoms. [5] Fluorine and chlorine are

gases at room temperature, bromine is a liquid, and iodine is a solid. The London forces are thought to be arise from the motion of electrons.

When we put energy into a substance, what
Gwar [14]

Answer:

i dunno if this helps :(

Explanation:

Heat is energy transferred between substances or systems due to a temperature difference between them, according to Energy Education. As a form of energy, heat is conserved, i.e., it cannot be created or destroyed. It can, however, be transferred from one place to another.

What is the percent rate of change in function y = \((0.99)^x\)? Determine whether the function represents exponential growth or
storchak [24]

Answer: The correct answer is 1%: exponential decay.

Explanation: We are given a function:

y=(0.99)^x   ...(1)

To determine the percentage rate of change in function, we compare the given function with the general form of exponent function, which is:

y=a(1+r)^x    ...(2)

Comparing both the equations, we get:

1+r=0.99

r=-0.01

We take 'r' in percentage, so converting this above value in percentage, we get:

r=-0.01\times 100=-1\%

As the value of 'r' is negative, it means that the exponent is decaying, so the percentage rate of change in function will be 1% and it will be exponential decay.
