Answer:
Suggest a structural reason why carbonic anhydrase synthesized with Ni2+, Fe2+, or Mn2+ in place of Zn2+ gives an enzyme with less catalytic efficiency.
Answer:
D.) molecule
<h3>When the same or different atoms combine together they for a molecule</h3>
Atomic number is the number of protons in an atom and is equal to the number of electrons also.
Atomic number = 44.
Hence number of electrons in an atom of this element (with atomic number 44) = 44 electrons.
Answer:
13
Explanation:
Let's consider the unbalanced equation for the combustion of propane.
C₃H₈ + O₂ ⇒ CO₂ + H₂O
We will begin balancing H atoms by multiplying H₂O by 4.
C₃H₈ + O₂ ⇒ CO₂ + 4 H₂O
Now, we balance C atoms by multiplying CO₂ by 3.
C₃H₈ + O₂ ⇒ 3 CO₂ + 4 H₂O
Finally, we get the balanced equation multiplying O₂ by 5.
C₃H₈ + 5 O₂ ⇒ 3 CO₂ + 4 H₂O
The sum of the coefficients is 1 + 5 + 3 + 4 = 13.
Answer:
90.5g de NOCl en 2500 g de solución blanqueadora.
Explanation:
Una solución de concentración 3.62% en peso de hipoclorito en una solución blanqueadora contiene 3.62g de NOCl por cada 100g de solución. Con esta relación, podemos encontrar la masa de NOCl en 2500g de solución, así:
2500g de solución * (3.62g NOCl / 100g solución) =
<h3>90.5g de NOCl en 2500 g de solución blanqueadora.</h3>
