Answer:
Considering the half-life of 10,000 years, after 20,000 years we will have a fourth of the remaining amount.
Explanation:
The half-time is the time a radioisotope takes to decay and lose half of its mass. Therefore, we can make the following scheme to know the amount remaining after a period of time:
Time_________________ Amount
t=0_____________________x
t=10,000 years____________x/2
t=20,000 years___________x/4
During the first 10,000 years the radioisotope lost half of its mass. After 10,000 years more (which means 2 half-lives), the remaining amount also lost half of its mass. Therefore, after 20,000 years, the we will have a fourth of the initial amount.
Answer:
Es la capacidad, el poder de un átomo en una molécula para atraer a los electrones hacia sí.
Explanation:
Answer:
2s and 2pₓ
Explanation:
The figure below shows the orbitals of HCN.
The sp orbitals on C are formed by the hybridization of its 2s orbital and its 2pₓ orbital
.
2s + 2p ⟶ 2sp + 2sp
C or d because ik it’s not consolidated
