Answer:
5.733 days
Explanation:
To convert from minuets to days we must first convert minuets to hours. To do this we divide by 60 since there are 60 minuets in one hour.
8255 min ÷ 60 = 137.6 hr
Now that we have the amount of hours we can convert to days by dividing by 24 since there are 24 hours in one day.
137.6 hr ÷ 24 = 5.733 days
Yes it is. Copper is the same mass and volume. Plus all pennies are made of copper
Answer:
CERN uses a series of particle accelerators to accelerate protons to their end speeds in the LHC. The first accelerator is the linear accelerator Linac 2. At one end of Linac 2, hydrogen from a bottle is passed through an electric field to strip off the electrons, leaving positively charged protons.
Explanation:
Answer:
89.4%
Explanation:
Initially, there is 5.0 of the acetanilide in 100 mL of water, then the solution is chilled at 0ºC. The solubility represents the amount that the solvent (water) can dissolve of the solute (acetanilide). So, at 0ºC, 100 mL of water can dissolve till 0.53 g of the compound, the rest will precipitate and will be recovered.
So, the mass that is recovered is 5.0 - 0.53 = 4.47 g
The percent recovery is:
(4.47/5)x100% = 89.4%
