Question 3 is uniformitarianism
Question 4 is sedimentary rock
They are made of different color of waxes
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.
Hydrogen i suppose is the right one
I would say the answer is... <span>C. AgNO3 + LiOH AgOH + LiNO3

Good luck!!
