At decomposition of solid substance with formation of gas leads to increase in an entropy. For example,
60°C
NH₄NO₂(s) = N₂(g) + 2H₂O(l)
true
Answer:
Al is aluminum. Bromine gas is Br2
Explanation:
Al + Br2 = AlBr3
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
