Answer:
It is the closest sir.
Have an amazing day and enjoy. P.S Good luck!
Explanation:
1. 1/16 x 1 000 000= 62500
2. Each half life is 5750 years long
3. The end of a half life is found by dividing the beginning of the half life by 2.
4. The number 62500 is between the 7th and the 8th half lives (refer to the number of 14C atoms on my table)
5. The 7th half life is 40250 years, and the 8th half life is 46000 years.
6. Therefore, your estimate would be a number roughly in the middle of 40250 and 46000 (for example: 43000)
Hope this helps :)
Answer: In the reaction rate law the rate is expressed in terms of concentrations of species. It is important to know how much time a reaction will take to complete itself. It depends on some factors. Temperature, concentration of component, catalyst and pressure. On increasing these factors the rate of reaction of a respective reaction increases. It doesn't depends upon reactor type.
Molecules in food contain chemical energy that cells use to produce ATP = adenosine triphosphate.
The Atomic nucleus has a charge of 0.
Explanation: an atom consists of of positively charged nucleus, surrounded by one or more electrons (which are negatively charged.) The positive charges equal the negative charges so the atom ends up having no charge.
