Answer:
your at the sun
Explanation:
it's very hot and super dense
The Half life is the time taken for a radioisotope or a radioactive substance to decay by half its original amount. The half life of carbon 14 is 5600 years.
Original mass is 100%
Remaining amount is 24%
Therefore; 0.24 = 1 × (1/2)^n
n = log 0.24/log 0.5
= 2.06
therefore, the age of the fossil is 5600×2.06
= 11529.8
≈ 11529 years

Answer:
Iodine has more electron levels (rings) than fluorine.
Explanation:
On the periodic table, fluorine is on period 2 so it has 2 outer rings, iodine is on period 5 so it has 5 outer rings. The more rings the higher radius.
Solubility is the amount of solute that can dissolve in a given solvent at a specified temperature or pressure. Therefore, solubility is affected by pressure and temperature such that increase in temperature increases the rate of solubility of substances. In additional solubility depends on the molecular size of the solute such that when other factors are kept constant then a solute with small particles will dissolve more faster. Therefore, to increase the rate of solubility Ryan may; increase the temperature of water.
