700 milliion years. The definition of half-life is the period of time during which one-half of the atoms of an element undergo decay into other elements.

How long does it take for light and sound to reach earth?
The length of time it takes light to reach earth has a lot to do with where it starts out from. If it starts from the moon, it takes about 1.5 seconds. If it starts from the sun, it takes about 8 and 1/3 minutes. If it starts from the nearest star, it takes about 4.4 years. If it starts from the North Star, it takes about 230 years. If it starts from the Andromeda Galaxy, it takes about 2.5 million years. Sound can't reach the earth from any other body. Sound needs air to travel through, and there's no air past a couple hundred miles above earth's surface. Sound can't even travel between two astronauts standing on the moon 2-ft apart.
Why should the endpoint be taken as the faint pink color of the indicator?
The faint pink color indicates that the solution is nearing the endpoint of the titration, where the reaction is nearly complete. Taking the faint pink color as the endpoint ensures accurate results without risking over-titrating the solution, which could lead to inaccurate readings.
How far is the Andromeda?

The halflife of Na24 is 15 hours When there are 1000 atoms of Na24 in a sample a scientist starts a stopwatch The scientist stops the stopwatch at 45 hours there are atoms of Na24 rema?
There will be 125 atoms of Na24 remaining in the sample after 45 hours. This calculation is based on the fact that after 3 half-lives (45 hours/15 hours per half-life), the original 1000 atoms would have reduced by a factor of 2 three times, resulting in 1000/2/2/2 = 125 atoms remaining.
