Why does the weight of the dry ice go down while it’s sitting on the scale

Chemistry

Dry ice is colder, heavier, less messy than regular ice. If I understood your question correctly, the mass of it would decrease bc it is being dispersed into the air as carbon dioxide.

What is the reason carbon atoms are the most versatile building blocks of the molecules used by living organisms?
WITCHER [35]

Explanation:

Atomic number of carbon is 6. So, 4 valence electrons are present.

Therefore, it can form 4 covalent bonds with varying bond angles by sharing its valence electrons.

Catenation is also an important property of carbon. Catenation is bonding with atoms of same element. Carbon skeleton can be formed in any direction and can vary in length, branching, and ring structure.

Elements required for making most of the molecules in living organisms are:

C, H, N, O, P and S

Carbon easily form covalents with other 5 elements.

These properties make carbon most versatile building blocks of the molecules used by living organisms.

if the atomic number of neon is 10, how many dots would be needed to represent the outer electrons for an atom of neon in an ele
Neko [114]

Answer: 8 dots would be needed to represent the outer electrons for an atom of neon in an electron dot diagram.

Explanation:

Electron-dot diagram is also known as Lewis-dot structure. It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.  The valence electrons are represented by 'dot'.

As atomic number of neon is 10 and we know that neon has 10 electrons with electronic configuration of 2,8 and thus has '8' valence electrons.

Therefore, the total number of valence electrons is 8 and 8 dots would be needed to represent the outer electrons for an atom of neon in an electron dot diagram.

How can a substance gain energy and still be frozen
emmasim [6.3K]
When a substance is under less pressure, or is under higher heat, it is gaining energy still. The particles vibrate faster, and get slightly more spaced out. If you take a metal ball and ring that fits perfectly around the ball, then heat the ball up with a flame, you will notice that the ball doesn't fit through the ring. The ball is still solid, but because it had more heat, it had more energy.

Which element is the least reactive? Neon, Chlorine, Gallium or Tin
Katen [24]
Noble gases are supposed to be the least reactive elements so I’m assuming Neon would be the most least reactive out of all of them.
