According to Diagram B, look at the 1600 elevation until you see the descending air line touches it. Then look down at the temperature at the bottom of the graph. It is between 0 degrees to 5 degrees.
The only number that is between that range is 2 degrees C.
Lithium fluoride is the compound name
17) 8.4 / 20 x 100
18) 20 . 0.5150
19) 6,50% because (as you said) the law of definite proportions states that regardless of the amount, a compound is always composed of the same elements in the same proportion by mass
Answer: 25°C=77°F
Explanation:
FORMULA
F=9/5 C+32
-----------------------------------
Given: C=25°
F=9/5 C+32
F=9/5 (25)+32
F=45+32
F=77°
