Explanation:
The rubber is a non-conductin insulator
the metal clamps with teeth and attached wires are the conductors of electrical current
Answer:
a) quadruple covalent bond
Explanation:
Quadruple covalent bonds are the strongest covalent bonds. The more the number of bonding pairs, the stronger the bond becomes.
- A covalent bond is formed by sharing of electrons between two species.
- They are usually between compound with similar electronegativities.
- The number of bonds between the atom determines the bond strength.
Single < double < triple < quadruple covalent bonds.
Answer:
1) Carbon-14 is a naturally occurring carbon isotope.
2) Carbon-14 has a known half-life.
3) Carbon-14 is present in all living organisms.
Living things have carbon-14 in their organism, but when they died, the amount of C-14 they contain begins to decrease as the C-14 undergoes radioactive decay. Measuring the amount of C-14 in a sample from a dead plant or animal when the animal or plant died.
The half-life of C-14 is about 5730 years.
Half-life is the time required for a quantity (in this example number of radioactive nuclei of carbon-14) to reduce to half its initial value.
Hope this helps and also this question was already on Brainly check it out I just copied lol :)
