Answer:
A chemical change is a change in the chemical makeup of a substance and results in a new substance. Ice and water both have the same chemical makeup - ice is just a different state and has the same atoms but in an expanded form.
Explanation:
Answer: None of the above
Explanation: It is not possible for any of these animals to undergo metamorphosis.
The atoms are all electrically neutral because the number of protons is equal to the number of electrons.
<h3>What is electrical neutrality?</h3>
An atom is electrically neutral when the number of protons is equal to the number of electrons.
In the cases of H-1, H-2, and H-3, the nuclides have one electron an one proton. The different mass numbers arise from differences in the number of neutrons. Hence in all cases, the nuclides are electrically neutral.

Answer:
hydroperoxyethane
Explanation:
tomsFor the Lewis structure we have to remember that all the atoms must have <u>8 electrons</u> (except for hydrogen). In this structure, we have three types of atoms, Carbon, Hydrogen and Oxygen. So, we have to remember the <u>valence electrons</u> for each atom:
-) Carbon : 4 electrons
-) Hydrogen: 1 electron
-) Oxygen: 6 electrons
We can start with the "
" part. We can put 3 hydrogen bond arroun the carbon. We can use this same logic with "
". Finally for oxygens, we can put it one bond with and a bond between oxygens with a final bond with hydrogen to obtain <u>hydroperoxyethane</u>.
See figure 1 for further explanations.
