Answer:
The answer to your question is: letter C) 5730
Explanation:
Data
Originally Carbon - 14 254 g
Currently Carbon - 14 127 g
Half-life of Carbon -14 is when half of the original amount of Carbon disintegrates.
Then, if originally there were 254 and now there are 127, only one half life passed.
Half life of carbon -14 is 5730 years old.
Answer:
because of the material, they are made of
Explanation:
like a paperclip and a car door maybe they both are metal or steel whatever they both can conduct energy. because of what they are made of.
i hope this helps and sorry i am rushing, i also just woke up

Answer:
2H₂O (l) ⇄ H₃O⁺ (aq) + OH⁻(aq)
Explanation:
The autoionization of water is defined as a chemical reaction where there is an equilibrium in which two water molecules react producing an hydronium ion and a hydroxide ion. This is also defined as the autoprotolysis of water, and is based on its amphoteric nature.
The substance that can donate protons as well as receive them is defined as amphoteric. In this way, the water behaves amphoteric as it donates a proton as an acid of Brownsted Lowry or if it receives a proton, being a base.
NH₃ + H₂O ⇄ NH₄ + OH⁻ Kb
In this case, water behaves as an acid, it donates the proton to ammonia (a base)
CH₃COOH + H₂O ⇄ CH₃COO⁻ + H₃O⁺ Ka
For this case, water behaves as a base, it recieves the proton from the acetic acid (acid)
