Explanation:
Immunofluorescence or immunoperoxidase assays are commonly used to detect whether a virus is present in a tissue sample. These tests are based on the principle that if the tissue is infected with a virus, an antibody specific to that virus will be able to bind to it.
Answer:
120 gramos de CO₂
Explanation:
La ecuación química balanceada para la combustión del hidrocarburo propano (C₃H₈) es la siguiente:
C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O
Por lo tanto, 1 mol de C₃H₈ produce 3 moles de CO₂. Para convertir las moles a gramos usamos el peso molecular (PM) de cada compuesto:
PM(C₃H₈)= (3 x 12 g/mol C) + (8 x 1 g/mol H) = 44 g/mol
masa de C₃H₈ = 1 mol x 44 g/mol = 44 g
PM(CO₂) = (1 x 12 g/mol C) + (2 x 16 g/mol O) = 44 g/mol
masa de CO₂ = 3 mol x 44 g/mol = 132 g
Ahora podemos ver que se producen 132 gramos de CO₂ (3 moles) a partir de 44 gramos de C₃H₈ (1 mol) ⇒ 132 CO₂/ 44 g C₃H₈
Multiplicamos la relación estequiométrica por la cantidad de propano que tenemos para calcular la cantidad de CO₂ producida:
40 g C₃H₈ x 132 CO₂/ 44 g C₃H₈ = 120 g CO₂
Entonces, se producen 120 gramos de dióxido de carbono al quemar 40 gramos de hidrocarburo C₃H₈.
The answer is d because it makes sense
What I did was I said the plates moved 3 centimeters per year and and times it by 100 million years and you get how far the plates have moved against each other. When they move that far against each other, the land would break and pile up to create mountains. Under the sea, the earth would collide and and create a chain of volcanoes. I got a 4/4 for this question, hope this helps you. Good luck!
C. 50%. The tall pea plant is Tt and the short pea plant is tt. If you cross both plants together there will be two Tt and two tt.
