260 miles with 12 gallons of gas
260 miles/12 gallons=21.6667 miles/1 gallon
286 miles/(21.6667 miles/1 gallon)=13.2 gallons of gas
Answer:
The number of electrons in the outermost shell of an atom determines its reactivity. Noble gases have low reactivity because they have full electron shells. Halogens are highly reactive because they readily gain an electron to fill their outermost shell.
Explanation:
Answer:
the first energy level is closest to nuclear the second energy level is a little farther away than the first
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
