To solve this problem, we can simply calculate for the
dose by multiplying the volume of solution containing Selenium 75 and the
activity of the Selenium 75. That is:
dose = 4.1 mL * (45 μCi/mL)
dose = 184.5 μCi
Answer:
There are 19 atom sin total in antimony silicate, 
.
Explanation:
Number of antimony atoms = 4 × 1 = 4
Number of silicon atoms = 3 × 1 = 3
Number of oxygen atoms = 3 × 4 = 12
Number of atoms in antimony silicate:
= 4 + 3 + 12 = 19
There are 19 atom sin total in antimony silicate, .
Answer:
The log will float on the water because its density is lower than the liquid, so it will stay at the top due to Archimedes' principle.
Answer:
you have to attach the diagram
Explanation:
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.
