Answer:
The balanced reaction in the acidic medium is:
Explanation:
1) 
( oxidation)
Balance oxygen by adding water :
Now , balance hydrogen by adding hydrogen ions on the side where hydrogen are less.
Add electrons to balance charge where positive charge is more.

2) 
(reduction)
Balance oxygen by adding water :
Now , balance hydrogen by adding hydrogen ions by adding them on the side where hydrogen are less.
..[2]
Add electrons to balance charge where positive charge is more.

The balanced reaction in the acidic medium is:
Answer:
The correct option is;
B) 179 g
Explanation:
The parameters given are;
Mass of H₂ that takes part in the reaction = 2.23 g
Molar mass of hydrogen gas, H₂ = 2.016 g
Number of moles, n, of hydrogen gas H₂ is given by the relation;
Chemical equation for the reaction;
H₂ + Br₂ → 2HBr
Given that one mole of H₂ reacts with one mole of Br₂ to produce two moles of HBr
1.106 mole of H₂ will react with 1.106 mole of Br₂ to produce 2 × 1.106 which is 2.212 moles of HBr
The molar mass, of HBr = 80.91 g/mol
The mass of HBr produced = Molar mass of HBr × Number of moles of HBr
The mass of HBr produced = 80.91 × 2.212 = 178.997 g ≈ 179 grams
Therefore, the correct option is B) 179 g.

Answer:
Temperature is one of the major factors that affects the rate of change of the liquid colour, this is because ; like when if you freeze hot water the ice formed will be clear transparent, while on the other hand, if we freeze cold water it would be foggy inside the ice. This change occurs because of the temperature difference of the cold and hot water.
