BIOLOGY - Carbon-14 is a radioisotope of carbon that has a half-life of about 5,730 years. A geologist is using carbon-14 dating on charcoal samples to find the age of ancient forest fires. Match the approximate age to each charcoal sample in the following two questions. Charcoal Sample #1 has 50% of its carbon-14 remaining.
What is the approximate age of Charcoal Sample #1?
Group of answer choices:
A: 12000 years old
B: 3000 years old
C: 6000 years old
D: 18000 years old



Charcoal Sample #2 has 6% of its carbon-14 remaining.

What is the approximate age of Charcoal Sample #2?
Group of answer choices
A: 18000 years old
B: 6000 years old
C: 24000 years old
D: 12000 years old

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
