Answer: wait im gonna search some info.
Explanation:I come back with an asnwer for you
H:O = 4:5;
(UO₂)₂ = 4 O atoms;
(PO₄)₂ = 8 O atoms:
8H₂O = 16 H atoms + 8 O atoms;
Total = 16 H atoms + 20 O atoms;
H:O = 16:20 = 4:5
Answer:Then a few days later the activity of the sample will be due to have more of Nuclides Y than X
Explanation:
This is because half life of nuclide X is about a day which is less than Y having half life of about a week, After a few days, we would observe that X would have disintegrated more while Y will still be predominant since it disintegrate slower than X. The time it takes for X to disintegrate will always be faster than Y.
Answer:
d. 26.0 km
Explanation:
If the temperature in the region increases with depth by about 25 °C /km, then at a depth of 2 km the temperature would be 50 °C higher, at a depth of 3 km the temperature would be 75 °C higher and so on.
<u>The only way for finding melted quartz would be if the temperature is at least 650 °C.</u>
- Temperature = 25 °C /km * Depth
We put the data given by the problem and <u>solve for Depth</u>:
- 650 °C = 25 °C /km * Depth
