Question 1<br><br> Of the following which displays a positive energetic process?
TiliK225 [7]

We can describe a positive energetic process as any process which increases the internal energy of the system.

A positive energetic reaction or process is often referred to as being Endothermic. This means that the system which is performing the process absorbs energy. Some examples include:

  • Boiling an Egg
  • Roasting food over a fire (the food is the reference system)

etc

Therefore, we can confirm that a positive energetic process is one in which the system in question absorbs energy, thus increasing its internal energy.

<em>Since I could not locate the options online, I have provided a general explanation of the concept coupled with a few examples.</em>

An atom of which of these elements most likely forms an anion? A. AI B. Br C. Ca D. Mg
Papessa [141]
The answer is B. A good way determine this is how far right the element is on the periodic table. The further right the element is, the more electronegative it is meaning it is more willing to accept an electron. This can be explained using the valence electrons and how many need to be added or removed to complete the octet. The further right you are, the easier it is for the element to just gain a few electrons instead of loose a bunch. Noble gases are the exception to this since they don't normally react though.

Which answer below correctly identifies the type of change and the explanation for the boiling of water?
Lynna [10]

physical change because even though gas formation was observed, the water was undergoing a  state change, which means that its original properties  are preserved

Explanation:

The boiling of water is a physical change because the original properties of the water is preserved.

  • A physical change is the one that alters the physical properties of matter.
  • This kind of change is easily reversible as the water can be cooled back.
  • No new kinds of matter is produced in this kind of change .
  • The molecules of the matter still retains their property after.

During the boiling of water, intermolecular bonds called hydrogen bonds between the water molecules are broken. This makes the individual molecules free.
