Answer: covalent bond
Explanation: The carbon-hydrogen bond is a bond between carbon and hydrogen atoms that can be found in many organic compounds.
A elephant egg cell has 28 chromosomes.
Both elephant egg and sperm cell make a zygote with 56 chromosomes.
Ca(OH)₂: strong base
pOH = a . M
a = valence ( amount of OH⁻)
M = concentration
Ca(OH)₂ ⇒ Ca²⁺ + 2OH⁻ (2 valence)
so:
pOH = 2 x 0.005
pOH = 0.01
pH = 14 - 0.01 = 13.99
