Answer:
The correct answer is - 1/4096.
Explanation:
In the starting, there is that the number of atoms is N
0
.
The number of half-lives in this case, = 300/ 25 = 12
After the first half-lives or 25 days, N
1
=
N
0
/2
the half life is that time where half of the sample had decay.
After the second half-life or 50 days, N
2
=
N
1
/2 =
N
0
/4
.
There is division by two the original amount, then after four times you divide four times for 2 that means that you divide by 2
^12 =4096
.
So the final amount remain is N
12
=
N
0
/4096 or 1/4096.
Answer:
1. chemical name: Sucrose
Explanation:
the chemical´s element amount is 3
What experiment are u talking about??
1) This is a definition.
2) Protons are given by the bottom number (since atomic number = number of protons).
3) Neutrons = (mass number)-(atomic number), which are the top and bottom numbers, respectively.
4) Nuclear fusion involves combining two things together, which is only reflected by the last option.
5) This is a fact.
6) This is a fact.
7) This is a fact.
8) This is a fact.
9) The correct option is the explanation.
