Answer:
4.23.
Explanation:
<em>∵ pH = - log[H⁺].</em>
<em>For weak acids:</em>
∵ [H⁺] = √(ka)(c).
∴ [H⁺] = √(3.5 × 10⁻⁸)(0.10 M) = 5.92 x 10⁻⁵.
∴ pH = - log[H⁺] = - log(5.92 x 10⁻⁵) = 4.2279 ≅ 4.23.
Answer:
The answer is a carbon isotope.
Explanation:
Carbon has 6 protons and electrons so the atom is neutral.
However it is a carbon isotope because it has more neutrons than protons so be aware of that
Answer:
C.) Chromosomes
Explanation:
Nucleotides are made up of three parts: a deoxyribose sugar, a phosphate, and a nitrogen base.
Chromosomes are long, condensed strands of DNA.
Ga’s electronegativity is 1.81 and Ca’s is 1.00 . Does that help?
