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
Answer:
it is option 2.
Explanation:
when balancing equations, both sides need to have the same number of the element.
4As + 3O2 - -> 2As2O3
4 as. 4 as (2×2=4)
6 o (because 3×2=6) 6 o (2×3=6)
since there are the same amount of each element on both sides, the equation is balanced.
