Answer:
- 19501130 dhakdjsu dhakdjsu 2
Explanation:
Answer:
When an organism dies, it is usually destroyed by other forms of life and by weathering processes. On rare occasions some body parts—particularly hard ones such as shells, teeth, or bones—are preserved by being buried in mud or protected in some other way from predators and weather. Eventually, they may become petrified and preserved indefinitely with the rocks in which they are embedded. Methods such as radiometric dating—measuring the amounts of natural radioactive atoms that remain in certain minerals to determine the elapsed time since they were constituted—make it possible to estimate the time period when the rocks, and the fossils associated with them.
The element that has the smallest atomic radius is <u>titanium</u>
<em><u>explanation</u></em>
- Calcium,potassium, scandium and titanium are in period 4 in the periodic table.
- Generally the atomic radius decreases across the period (from the left to the right) . This is because across the period there is increase in nuclear charge which make electrons been strongly attracted to the nuclear.
- Titanium is in atomic number 22 thus it has more nuclear charge that calcium,potassium and scandium therefore titanium has the smallest atomic radius.
Answer:
10.56L
Explanation:
The following were obtained from the question given :
P1 = 845mmHg
V1 = 4.6L
P2 = 368mmHg
V2 =?
We can calculate the new volume by using Boyle's law as follows;
P1V1 = P2V2
845 x 4.6 = 368 x V2
Divide both side by 368
V2 = (845 x 4.6) / 368
V2 = 10.56L
