Answer:
Explanation:
Intravenous (IV) tubing or valves can prevent back flow and contamination of injection devices. This is also false! The truth is that everything from the syringe or medication bag to the patient's IV catheter is a single interconnected unit.
The amount of grams of hydrogen that are in the water sample is;
3.985 g
<h3>Avogadro's number</h3>
We are given that;
Number of moles of oxygen in a sample of water = 12 × 10²³
- Now, the chemical formula of a molecule of water is H₂O. This means that for every 1 atom or molecule of oxygen, there must be 2 hydrogen atoms or molecules present.
Since Number of moles of oxygen in the sample is 12 × 10²³, then number of moles of hydrogen will be twice that = 2 × 12 × 10²³ = 24 × 10²³ moles
Now, molar mass of hydrogen is 1 g/mol and we know that;
Molar mass = Avogadro's number(6.023 × 10²³) moles
Thus;
6.023 × 10²³ moles = 1 g/mol
Thus; 24 × 10²³ moles of hydrogen = ( 24 × 10²³ × 1)/(6.023 × 10²³)
⇒ 3.985 g

SAT tests are created to confuse you, but don't worry! Here's my answer: Identifying an alternate route before you need one. Every Uber or Taxi driver is forced to do so before taking a road. Hope this helps!
Stories could either have a single or multiple narrator(s). Hence, stories having multiple narrators would usually have a non-linear plot.
- Multiple narrators in a story means that characters in the story are numerous, hence, acts and scenes would have to be passed on to these characters from time to time.
- As for single narrator, this is not the case as the number of actors are very limited.
Hence, because multiple narrators often hinders a story to be chronologically ordered, then it would result in a non-linear plot.
