I think how it burns is not a physical property since that involves a chemical change while all of the other properties involve the physical structure or a physical change.
I hope this helps.
D. quantitative properties
Boiling point and freezing point depression are both values that can be represented quantitatively (in number form).
Answer:
C₆H₁₈
Explanation:
Let's say x is the subscript of carbon and y is the subscript of hydrogen. We know from the empirical formula that the ratio of x to y is 2 to 6.
x / y = 2 / 6
We also know from the molar mass that:
12.01x + 1.01y = 90.21
Solving the system of equations:
2y = 6x
y = 3x
12.01x + 1.01(3x) = 90.21
12.01x + 3.03x = 90.21
15.04x = 90.21
x = 6
y = 3x
y = 18
The molecular formula is therefore C₆H₁₈.
Answer:
The male cone
Explanation:
The male cones, which produce pollen, are usually herbaceous and much less conspicuous even at full maturity.
