Answer:k
Explanation:
Atomic theory would be the theory or explanation of the function of atoms and their relationship with each other.
First, we convert the moles of each substance into the concentration using the volume of the reactor.
[SO₃] = 0.425/1.5 = 0.283 M
[SO₂] = 0.208 / 1.5 = 0.139 M
[O₂] = 0.208/1.5 = 0.139 M
The equilibrium constant is calculated by:
Kc = [SO₃]² / [O₂][SO₂]²
Kc = (0.283)²/(0.139)(0.139)²
Kc = 29.8 = 2.98 x 10¹
The answer is C
Answer:
16
Explanation:
4 nitrogen (N) atoms and 12 (3×4) atoms in Hydrogen (H)
Total = 4 + 12 = 16 molecules
Blood should NOT be stored in an airtight container
<h3>Explanation:</h3>
We can store blood by dried it on a swab. To collect the dried blood, we should moisten a sterile cotton swab using distilled water or tap water, then shake the swab to remove excess water. Gently swab the stain with the moistened swab tip until the swab thoroughly absorbs the blood.
We can store blood also in the dried blood stains and as a scraping. The fresh collected blood, dried blood stains, wet blood stains are contained the DNA.
Airtight containers are the plastic used to make the durable containers and it is free from BPA and has been graded to be safe to be used with food supplies. The lid of this container has an innovative airtight mechanism which helps to maintain the airtight environment inside the container.
According to book "Criminal Investigation" By Ronald F. Becker on page 114, the airtight containers can cause condensation of moisture within the container and result in bacteria that can destroy, alter or contaminate the blood.
Blood components should be stored at temperatures storage in accordance with the requirements listed. Failure to follow correct storage requirements result in decreased transfusion efficacy
