Carbon dating relies on the ratio of Carbon-12 and Carbon-14 in an organic substance
D. NaOH + HCI NaCl + H,0
Explanation:
The last option is a double displacement/replacement reaction.
This reaction is a neutralization reaction in which an acid combines with a base to produce salt and water only.
NaOH + HCl → NaCl + H₂O
- A double displacement reaction is one that occurs between ionic compounds.
- In this reaction, there is an actual exchange of reaction partners.
One of the following conditions serves as a driving force;
- Formation of water or any other non-ionizing compound
- Liberation of gases
- Formation of a precipitate

Answer:
730.4 m
Explanation:
The sound waves travels with a uniform motion (=constant velocity), therefore we can calculate the distance it travels using the formula:
where
d is the distance
v is the speed of the sound wave
t is the time taken
In this problem we have:
v = 332 m/s is the speed of sound in air
t = 2.2 s is the time elapsed
Therefore, the distance between the tower and the person is
If you were somehow magically transported to Jupiter, your mass
would not change, but your weight would become roughly 2.5 times
your Earth weight.
