Can something be created without atoms?

Actually, most things are made up of atoms. Aside from the obvious (atoms themselves, their components and their components relatives), the particles that mediate the fundamental forces (gravitons, photons, gluons, and W and Z bosons, though to be fair only the last two have any actual mass), dark matter, and dark energy are not made up of atoms.

Hope this helps

Answer:

Actually, most things are not made up of atoms. Aside from the obvious (atoms themselves, their components and their components' relatives), the particles that mediate the fundamental forces (gravitons, photons, gluons, and W and Z bosons, though to be fair only the last two have any actual mass), dark matter, and dark energy are not made up of atoms. Light, an electromagnetic radiation, is not made of atoms. The plasma in stars is not technically made of atoms because electrons and nuclei are not combined into atoms. In fact, since dark energy is theorized to make up some 3/4 of the universe and we're fairly certain that there's more dark matter than there is of the more familiar sort, it's possible - even likely - that atomic matter comprises less than 10% of the universe. So yeah, most of the universe is made up of non-atoms.

hope this helps:)

What evidence has allowed scientists to conclude that the common ancestor of modern chimps and humans lived around 7 million yea
tatyana61 [14]

Biological molecules such as proteins and DNA reveal differences between humans and chimps that would have taken around 7 million years to accumulate.

<h3>What is DNA?</h3>

All known animals and viruses have genetic information in the form of deoxyribonucleic acid, a polymer consisting of two polynucleotide chains that coil around one another to form a double helix. Ribonucleic acid is a type of nucleic acid, as is DNA.

The two DNA strands are known as polynucleotides because they are constructed from simpler monomeric units called nucleotides.

The four nucleobases that contain nitrogen—cytosine (C), guanine (G), adenine (A), or thymine (T)—along with deoxyribose and a phosphate group—make up each nucleotide. The sugar of one nucleotide and the phosphate of the following make covalent bonds, creating what is known as the phospho-diester linkage, which results in an alternating sugar-phosphate backbone.

¿Cuántos gramos de dióxido de carbono (CO2) se producen si se quema 40 gramos del hidrocarburo ( C3H8 )?
Valentin [98]

Answer:

120 gramos de CO₂

Explanation:

La ecuación química balanceada para la reacción de combustión del hidrocarburo C₃H₈ (propano) es la siguiente:

C₃H₈ + 5O₂ → 3CO₂ + 4H₂O

Por lo tanto, 1 mol de C₃H₈ produce 3 moles de CO₂. Ahora debemos convertir las moles a gramos utilizando el peso molecular (PM) de cada compuesto:

PM(C₃H₈)= (3 x 12 g/mol) + (8 x 1 g/mol) = 44 g/mol

1 mol C₃H₈ = 1 mol x 44 g/mol = 44 g

PM(CO₂) = 12 g/mol + (16 g/mol x 2) = 44 g/mol

3 mol CO₂ = 3 mol x 44 g/mol = 132 g

Por lo tanto, se producen 132 gramos de CO₂ a partir de 44 gramos de C₃H₈ y la relación estequiométrica es:

3 mol CO₂/1 mol C₃H₈ = 132 g CO₂/44 g C₃H₈

Finalmente, para calcular cuántos gramos de CO₂ se producen al quemar 40 g de C₃H₈, multiplicamos la relación estequiométrica por la masa a quemar:

masa CO₂ producida = 40 g C₃H₈ x 132 g CO₂/44 g C₃H₈= 120 g
