<h3><u>Answer;</u></h3>
= 71.96%
<h3><u>Explanation</u>;</h3>
1 mole of CS2 = 76.133 g
1 mole of SO2 = 64.06 g
1 mole of CS2 reacts with 3 moles of Oxygen to produce 2 moles of SO2
Moles of CS2 in 12.5 g = 12.5/76.133
= 0.164 moles
Mass of SO2 = 0.164 mol × 2 × 64.06
= 21.01168 g
Therefore;
Percentage yield of SO2
= 15.12/21.01168 × 100%
<u> = 71.96%</u>
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
Answer:
D.Subduction zones are near plate boundaries
Explanation:
Subduction zones are plate boundaries where two plates meet ,one plate is thrust beneath the other.Due to this earthquakes and Volcanic eruptions occurred. this geohazard affects millions of people around the globe, specifically at edge of the Pacific Ocean.This edges consists of many subduction zones. Megathrust is the largest earthquake occurred at the interface between the boundaries of the two plates.
