Creativity is a phenomenon whereby something somehow new and somehow valuable is formed. The created item may be intangible (such as an idea, a scientific theory, a musical composition, or a joke) or a physical object (such as an invention, a printed literary work, or a painting).
Scholarly interest in creativity is found in a number of disciplines, primarily psychology, business studies, and cognitive science, but also education, the humanities, technology, engineering, philosophy (particularly philosophy of science), theology, sociology, linguistics, the arts, economics, and mathematics, covering the relations between creativity and general intelligence, personality type, mental and neural processes, mental health, or artificial intelligence; the potential for fostering creativity through education and training; the fostering of creativity for national economic benefit, and the application of creative resources to improve the effectiveness of teaching and learning.

A picture of a lightbulb is associated with someone having an idea, an example of creativity.

How would the number of atoms in a 2.02g sample of hydrogen compare to the number of atoms in a 32.00g sample of oxygen
Answer:
Number of atoms is equal.
Explanation:
1 mol of anything contains NA particles.
NA is known as Avogadro's number, 6.02×10²³
We determined the moles of each compound. Both molecules are dyatomic,
H₂ → 2.02 g . 1mol / 2.016 g = 1 mol
O₂ → 32 g . 1mol / 32g = 1 mol
Both have the same amount of moles.
In conclussion, the number of atoms is the same in both samples.
What is natural gas and how does it work
Answer:
Natural Gas is a fossil energy source that formed deep beneath the Earth's surface. It is used in power plants to generate electricity by burning natural gas as their fuel.
Explanation: I hope this helped :)
Answer:
A molecule of natural gas is made up of carbon and hydrogen. When the hydrogen is segregated from the carbon and filled into a fuel cell, it fuses with oxygen to produce water, electricity, and heat. The carbon is released as carbon dioxide in smaller quantities than from gas turbines.

How much Pb(NO3)2 would need to be added to 100 mL of water to make a saturated solution at 40°C.
Answer:
70g of Pb(NO3)2 would need to be added
Explanation:
As you can see in the solubility graph of lead nitrate, Pb(NO₃)₂, the solubility of this salt (That is, the maximum amount of the salt that can be dissolved in 100g of the solvent producing a homogeneous solution) is 70g in 100g of water = 70g of the salt in 100mL of water.
A saturated solution is also defined as solubility: The maximum amount of a solute that can be dissolved in a solvent.
That means:
70g of Pb(NO3)2 would need to be added
what is the molarity of a solution prepared dissolving 317 g of CaCl2 into enough water to make 2.50 L of solution?
Answer:
1.14 M
Explanation:
Step 1: Calculate the moles corresponding to 317 g of calcium chloride (solute)
The molar mass of calcium chloride is 110.98 g/mol.
317 g CaCl₂ × 1 mol CaCl₂/110.98 g CaCl₂ = 2.86 mol CaCl₂
Step 2: Calculate the molarity of the solution
Molarity is equal to the moles of solute divided by the liters of solution.
M = moles of solute / liters of solution
M = 2.86 mol / 2.50 L = 1.14 mol/L = 1.14 M
Describe how the Sun and Earth formed.
Answer:
When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle and a solid crust.

Natalia dipped two feathers in oil. Then she dipped one feather in cold water and the other feather in hot water. She swirled both feathers around for 20 seconds, then removed them. Her results are in the table. Cold Water Hot Water Before Oil After Oil After Water Before Oil After Oil After Water Mass 1.2 g 4.5 g 4.2 g 1.2 g 4.4 g 3.5 g She also took a picture of each feather after swirling it in water. two feathers, each with oil and beads of water Was either the cold water or the hot water able to remove the oil? Explain your reasoning.
Answer:
The hot water was better for removing the oil.
Explanation:
You can see that because the mass went down more with the hot water. So, that means that more oil was taken out of the feather with hot water.
Answer:
The mass changed from 1.1grams to 4.5 grams. The appearance is another thing that changed when it got dipped in oil. The feather look like it lost some feathers or the feathers became transparent. The feather just looks soggy and heavier overall. I believe that if Natalia dips the feather covered in oil in cold water, the feather will remain the same. If she were to dip it in hot water, the feather will get rid of the oil mostly. Think about it, in the ocean the water is cold right? So when oil spills in the ocean it will stay there. Hot water is the best to remove the oil from the feather.

Students were given a sample of an unknown metal and told to determine
its density. They measured its mass as 26.4 g and its volume as 3.0 cm?
Use the chart to determine which metal the students were given.
Answer:
mass(m)=26.4g
volume (v)=3.0cm²
we have
density =m/v=26.4/3=8.8g/cm³
since it is equal to density of nickel.

Which of the following is an acid-base neutralization reaction?
A
Mg + 2 HCl → MgCl2 + H2
B
SiCl4 → Si + 2 Cl2
C
AgNO3 + KCl → AgCl + KNO3
D
HCl + KOH → KCl + H2O
Answer:
D
Explanation:
The reaction in which an acid reacts with a base to form salt and water is called acid base reaction.
here, HCL ( strong acid) reacts with KOH (strong base) and KCL (salt) and H2O (water) is formed.
The reaction between HCl and KOH is an example of acid-base neutralization reaction. Thus, the correct option is D.
An acid-base neutralization reaction refers to the reaction between an acid and a base that react to form a corresponding salt and water.
The anion from the acid and the cation from the base combine to form the salt. In this case, chloride ions (Cl⁻) and potassium ions (K⁺) combine to form the salt potassium chloride (KCl).
Salt formation leads to neutralization of the charge in the molecule, and also, the pH of the solution gets neutralized whose extent depends upon the strength of the acid and base used.
The hydrogen ions (H⁺) from the acid and hydroxyl ions (OH⁻) from the base combine to form water.

Alguien sabe como puedo saber si la bebida (gaseosa) al contener agua carbonatada, ¿esta pasa por electrolisi?, ya que el H2O, podria ser que puede ser de reaccion de sintesis, que seria H2+02------>H20? Seria hidrogeno gaseoso y pxigeno gaseoso formaria el agua carbonatada?, ayuda tengo esta duda >_
Answer:
Por formación de burbujas.
Explicación:
La presencia de burbujas en la superficie de la bebida ayuda a determinar si la bebida tiene gas carbonatado o dióxido de carbono. El gas de dióxido de carbono no se puede mezclar con agua ni disolver en agua normalmente. Se puede agregar mediante alta presión al agua para que cuando se coloquen en condiciones normales, el dióxido de carbono se libere en forma de burbujas. No, el gas hidrógeno y el gas hidrógeno no podrían formar agua carbonatada porque ambos son átomos diferentes. El agua carbonatada tiene gas dióxido de carbono, no gas hidrógeno.
