The answer is: b. Safety glasses and acid-resistant gloves.
Battery acid (sulfuric acid) has pH = 0.
Sulfuric acid (H₂SO₄) is a strong acid, it means that the solution of sufuric acid is more acidic (pH<7) than water (pH = 7).
Chemical dissociation of sulfuric acid in water:
H₂SO₄(aq) → 2H⁺(aq) + SO₄²⁻(aq).
Sulfuric acid can come in contact with eyes and hands, so it is important to wear safety glasses and acid-resistant gloves.

The Correct Answer is Eletric Current I think
Answer:
Mass of
produced = 32 g
Explanation:
Calculation of the moles of
as:-
Mass = 82.4 g
Molar mass of
= 122.55 g/mol
The formula for the calculation of moles is shown below:
Thus,
From the reaction shown below:-

2 moles of potassium chlorate on reaction forms 3 moles of oxygen gas
So,
0.67237 moles of potassium chlorate on reaction forms
moles of oxygen gas
Moles of oxygen gas = 1 mole
Molar mass of oxygen gas = 32 g/mol
<u>Mass of
produced = 32 g</u>
I don't think the answer is in one of the options- unless I am reading it wrong and there is a 'V' option.
The volume (V) of gas increases when the pressure of the gas decreases assuming all the other variables are held constant.
I hope this helps!
