Volume of O2 = 22.4 x moles of O2
= 22.4 x 1.2
= 26.88L
11 lb = 4.99 kg.
So, 74.85 mg should be given to the infant. Thus 0.75 mL of the suspension should be given.
Answer: 3.29 × 1023 atoms

B.) Mechanical
C.) Thermal
D.) Potential
Hope this helps!
Answer is: tin and zinc, because they standard potential as less than zero.
Tin and zinc are oxidized to tin and zinc cations (with +2 charge) and hydrogen anions are reduced to hydrogen molecules with neutral charge.
Zn → Zn²⁺ + 2e⁻; 2H⁺ + 2e⁻ → H₂.
<span>Oxidation is increase
of oxidation number and reduction is decrease
of oxidation number.</span>
