olga nikolaevna [1]3 years ago
4 0

Sr is  below Ca and to the right of Rb in the Periodic Table (see the attached image).

Reactivity increases from <em>top to bottom of a Group</em>. Sr is below Ca, so it is <em>more reactive</em> than Ca.

Reactivity decreases from <em>left to right in a Period</em>. Sr is to the right of Rb, so it is <em>less reactive</em> than Rb.

kolbaska11 [484]

The correct answer is option C, that is, hypothesis.  

The hypothesis is the starting building block in the scientific method. It is also illustrated as an educated guess, based on previous observation and knowledge. A hypothesis refers to a recommended solution for an unexplained event, which does not fit into the present accepted scientific theory.  

The fundamental concept of a hypothesis is that there is no pre-determined result. For a hypothesis to be considered as scientific hypothesis, it has to be something, which can be refuted or supported via carefully crafted observation or experimentation.

a 160 milligram sample of a radioactive isotope decays to 10 kilograms in 12 years. what is the half life of this element
Shkiper50 [21]

Answer:

3 years

Explanation:

Given data:

Initial amount of sample = 160 Kg

Amount left after 12 years = 10 Kg

Half life = ?

Solution:

at time zero = 160 Kg

1st half life = 160/2 = 80 kg

2nd half life = 80/2 = 40 kg

3rd half life = 40 / 2 = 20 kg

4th half life = 20 / 2 = 10 kg

Half life:

HL = elapsed time / half life

12 years / 4 = 3 years
