How to grow geodes crystals?
Answer:
They will need to be just a touch larger than your eggshells. We loved the glass bowls because it was so much easier to watch the growth process. Carefully crack several eggs and scramble the innards for lunch. Take your shells and wash them gently under warm water.
Explanation:
Explanation:
Pour about a half cup of hot tap water into a cup.
Stir in alum until it stops dissolving. ...
Add food coloring, if desired. ...
Set your eggshell or plaster geode inside a cup or bowl. ...
Pour the alum solution into the geode, allowing it to overflow into the surrounding container and eventually cover the geode.
it takes 15 hours to complete

Water travels through many different pathways within the hydrologic cycle. For example, water vapor in the atmosphere could condense into clouds, fall to Earth’s surface as precipitation, and then accumulate in a pond. If a horse drinks the water in the pond, which of the following is a likely next step for that water in the hydrologic cycle?
A.
The water will be permanently trapped and reused inside the horse's body.
B.
The water will be absorbed by the horse's skin and turned into carbon dioxide.
C.
The water will evaporate from the horse's stomach into the air.
D.
The water will leave the horse when the horse sweats or urinates.
Answer:
D
Explanation:
it's probably D because that what happens with every living creature. The other options don't make sense.

Explanation:
In which situation would the atoms in an object begin to move closer together during a phase change?
Group of answer choices
heat is removed as a gas turns into a liquid.
heat is removed as a liquid turns into a gas.
heat is added as a liquid turns into a solid.
heat is added as a solid turns into a gas.
When heat is removed as a gas turns into a liquid. In liquid state molecules are more closer than in gases. Hence, option a is correct.
What is a phase change ?The interconversion between states of matter is called phase change. The conversion of solid to liquid, liquid to gas, etc. are examples of phase changes.
In solid state, particles are closely packed and cannot move apart. The strong intermolecular forces can be weaken by applying energy. In liquid state, particles have some more space to low and in gases they are far apart.
When gases phase converts to liquid, the heat is removed from the system and make make the intermolecular forces stronger to bring molecules closer.

The octet rule states that atoms will gain, lose, or share valence electrons to get a full outer shell (orbital). Explain in your own words why this is an important rule to determine types of chemical bonds
someone pls help me i need it by today ty :)
Answer:
In covalent bonding, the octet rule is important because sharing electrons gives both atoms a full valence shell. As a result, each atom can consider the shared electrons to be part of its own valence shell.

In covalent bonding, the octet rule is important because sharing electrons gives both atoms a full valence shell.
What are chemical bonds?A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds.
The octet rule states that atoms are at their most stable when they have the electron configuration of a noble gas.
This means having eight outer shell electrons. Because of this, atoms tend to try and gain or lose electrons until they have eight electrons in their outer shell.
As a result, each atom can consider the shared electrons to be part of its own valence shell.

How many atoms of each element are chemical formula: 3K2O3.
How many atoms of each element are chemical formula: 2H3NCH3Br.
How many atoms of each element are chemical formula: 4Ar2CO3.
Each of them are different questions pls help me!!! I need to get this right to bring my grade up from a C to an A!!!
Answer:
In 3K2O3 - 6 K atoms, 9 O atoms
In 2H3NCH3Br - 12 H atoms, 2 N atoms, 2 C atoms, 2 Br atoms
In 4 Ar2CO3 - 8 Ar atoms, 4 C atoms, 12 O atoms
Explanation:
All you need to do is multiply the coefficient by the number of each atom in the compound. For example, H3NCH3Br has 1 nitrogen, 1 carbon, 1 bromine, and 6 hydrogens. If you have 2H3NCH3Br, just multiply all those numbers by 2.
