pH = 9.5
Explanation:
We know that the hydronium ion concentration is [H₃O⁺] = 3.16 × 10⁻⁹ M.
The formula for pH is:
pH = -lg[H₃O⁺]
We input the known values to find the pH:
pH = -lg[3.16 × 10⁻⁹]
pH = 9.5

Explanation:
Heat energy is transformed into electrical energy.
Answer:
0.238 M
Explanation:
A 17.00 mL sample of the dilute solution was found to contain 0.220 M ClO₃⁻(aq). The concentration is an intensive property, so the concentration in the 52.00 mL is also 0.220 M ClO₃⁻(aq). We can find the initial concentration of ClO₃⁻ using the dilution rule.
C₁.V₁ = C₂.V₂
C₁ × 24.00 mL = 0.220 M × 52.00 mL
C₁ = 0.477 M
The concentration of Pb(ClO₃)₂ is:

Answer:
There are chemical cross-links between the two strands in DNA, formed by pairs of bases. They always pair up in a particular way, called complementary base pairing: thymine pairs with adenine (T–A) guanine pairs with cytosine (G–C)
