Hi :)
I would say it’s C) A nurse forgets to feed a patient
Because, the patient may be unable to eat on his/her own, and it could need the energy from the food
Hope this helps!
There are three variables independent, dependent ,and controlled
Answer:
Chemical formula for the black iron oxide sample is FeO
Explanation:
<u>Given:</u>
Mass ratio of black iron oxide sample, Fe/O = 3.491
<u>To determine:</u>
The chemical formula
<u>Calculation:</u>
The mass ratio is Fe:O = 3.491 : 1
Mass of Fe = 3.491 g
Mass of O = 1.000 g
Atomic mass of Fe =55.85 g/mol
Atomic mass of O = 16.00 g/mol
Therefore, the molar ratio of Fe:O = 1:1
Hence, chemical formula is FeO
