Answer:
I think the insect would be the one in the second photo reading from left to right
Explanation:
the other insects:
the first of the first photo is a change of what would be the external surface of the insect, it is not the insect itself.
In the third photo, the insect has short legs with little grip, which indicates that it does not climb large areas on top, and finally, the 4 image is of an insect that lives in desert areas and is poorly coordinated in areas of high heat. and sand.
These are the reasons why I chose photo number two reading from left to right
They are different because of the number of electrons and protons and heir composition
<u>Answer:</u> D represents 222, E represents 86, F represents 234 and G represents 90.
<u>Explanation:</u>
The two given chemical reactions are a type of alpha decay processes. Alpha decay process is defined as the process, in which a heavier nuclei decays into lighter nuclei emitting alpha particle. The alpha particle released has a charge of +2 units. and is also known as a helium nucleus.
The isotope formed has atomic mass reduced by 4 units and atomic number reduced by 2 units.
So, for the chemical equations:
1.
D represents 222, E represents 86.
2.
F represents 234 and G represents 90.

Explanation:
Molality is the moles of solute per kg of solvent.
Moles of NH₄Cl = 2.4 / (14 + 4 x 1 + 35.5)
= 0.0448 mole
Molality = 0.0448 / (19.4 / 1000)
= 2.31 m
