Answer:
Hydrogen sulfide
Explanation:
A nonoxidizing acid is the acid which cannot act as oxidizing agent and thus furnish hydrogen ions. Example: HCl
Iron(II) sulfide reacts with nonoxidizing acid, say hydrochloric acid to give rotten egg smelling gas, H₂S (Hydrogen sulfide).
The reaction is shown below:
FeS (s) + 2HCl (aq) ⇒ FeCl₂ (s) + H₂S (g)
A general reaction is also shown below of the reaction of Iron(II) sulfide with any nonoxidizing acid, HX as:
FeS (s) + 2HX (aq) ⇒ FeX₂ (s) + H₂S (g)

srry i cant help u with this im so confuse like u just put all of it on there how would anybody answer tht!

Answer:
0.44 m is the molality
Explanation:
Molality means mol of solute in 1kg of solvent.
Solute → CdBr₂
Solvent → H₂O
Mass / Molar mass = 45.38 g / 272.21 g/m = 0.167 moles
1 g = 1x10⁻³ kg
375 g = 0.375 kg
0.167 m/0.375 kg = 0.44 m
The amino acid and which atom which has most to do with myoglobin’s ability to bind o2 is <u>histidine</u> and <u>haemoglobin</u> respectively
<h3>What is amino acid?</h3>
Amino acids simply refers to those molecular substances which combine together to form proteins. However, they are the end products of protein digestion
So therefore, the amino acid and which atom which has most to do with myoglobin’s ability to bind o2 is histidine and haemoglobin respectively
