Answer:
Explanation:
4FeS₂ + 11O₂ → 2Fe₂O₃ + 8SO₂.
4 moles of FeS₂ reacts with 11 moles of O₂
8 moles of FeS₂ reacts with 22 moles of O₂
Moles of O₂ available is 15 .
So O₂ is in short supply .
So O₂ is the limiting reagent.
Option (c) is the right choice.
Answer:
The number of active sites enzyme have is 1.
Explanation:
Mass of penicillinase = 4.10 μg =
1 g = 1000000 μg
The turnover number of the enzyme at 28 °C =
Moles of penicillinase =
Mass of antiboitic-amoxicillin =2.83 mg =
Moles of amoxicillin =
Moles of reactant which are converted into product per second:
=
Moles of product converted in 29.6 seconds:
Number of sites:
Answer:
8.2×10¯⁵ L
Explanation:
82 μL.
We can convert 82 μL to L by doing the following:
To convert from microlitre (μL) to litre(L), we need to know how many microlitre (μL) that makes up a litre (L)
Recall:
1 μL = 1×10¯⁶ L
Therefore,
82 μL = 82 μL × 1×10¯⁶ L/1 μL
82 μL = 8.2×10¯⁵ L
Therefore, 82 μL is equivalent to 8.2×10¯⁵ L
