Answer:
your answer should be B ANDC
Answer:
Decreasing order is as follows:
γ-rays > x-rays > red light > infrared > radio
Explanation:
Energy and wavelength are inversely related with each other.
In other words, energy decreases as the wavelength of electromagnetic radiation increases.
Order of wavelength for the given radiations are as follows:
Radio > infrared > red light > x-rays > γ-rays
So, order of the energy will be reverse.
γ-rays > x-rays > red light > infrared > radio

X: 1S²2S²2P⁶
Y: 1S²2S²2P⁶3S²3P⁶
The statement which is most likely correct about the two elements is
They will not react because both have a complete outermost shell and are stable.
<u><em>Explanation</em></u>
The P orbital can hold a maximum of 6 electrons,therefore the 2P orbital for x and 3P orbital for Y which are outermost subshell are fully filled .
This make element Y and x stable since they cannot react either by gaining or losing electrons.
Answer:
[C₆H₆] = 1.28 M
Explanation:
Let's determine the molar mass of benzene
Molar mass of benzene = 12g/m .6 + 6 . 1g/m = 78 g/m
Mol = mass / molar mass
9.99 g / 78 g/m = 0.128 mol
Molarity = mol/L
0.128 mol / 0.1 L = 1.28 M
