Answer:

Galaxies rotate in their center with parts of galaxies that are far away from centre.

Explanation:

Galaxies move throughout the space. It rotates around its center with the portions of galaxy that are far from the center and moves relatively slowly from other objects near the center.

Because of the Big bang explosion because of which the Universe have expanded, galaxies are going away from other galaxies. The galaxy cluster also moves around the cluster center.

¿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
