The answer would be 4 out of 10 which is 40 percent
Answer:
Yes, Lymph is another medium of circulation in the human body
Explanation:
Yes, Lymph is another medium of circulation in the human body. Lymph is part of lymphatic system which in turn is part of the circulatory system. The lymphatic circulatory system comprises of lymphatic vessels which carry clear fluid "lymph" towards the heart. The flow however is unidirectional
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
