Answer:
Explanation:
The MSDS is Material Safety Data Sheet of HCl. Among the major hazards of hydrochloric acid is corrosive and irritant to skin and eye contact. Permanent damage may be in case.
What are the precautions to be taken while handling chemicals?
General rules for handling chemicals
Do not return chemicals to their original packaging. ...
Keep chemical containers closed. ...
Never use a wrong or an unmarked reagent. ...
Never put spatulas, stirrers or other objects into a storage container for chemicals.
What are the major hazards and what precautions would you take when handling HCl?
.Handling. Wear a chemical-resistant apron, chemical-resistant gloves and chemical splash goggles at all times when handling HCl to protect your eyes and skin. Concentrated hydrochloric acid is toxic if inhaled, so avoid breathing it in and always handle it while under a fume hood.

My solving is a bit messy tho....HOPE I HELPED
Answer:
2 CO + O2 ———————-> 2 CO2
Mass of CO = 174 g
First change it into moles
No of moles = (mass in grams)/molar mass
Molar mass of CO = 30 g/mol
No of moles of CO = 174/30 = 5.8 mol
2 CO + O2 ———————-> 2 CO2
Equation shows that
2 moles of CO react with moles of O2 = 1 mol
1 mole of CO react with moles of O2 = 1/2
1 mole of CO react with moles of O2 = 0.5 mol
5.8 mole of CO react with moles of O2 =0.5x5.8
5.8 mole of CO react with moles of O2 = 2.9 mol
No of moles of O2 used = 2.9 mol
Then change it into no of molecules
No of molecules of O2 = 2.9x6.02x10^23
No of molecules of O2 used = 17.45x10^23
