Answer:
Option e and f are possible
Explanation:
Since we know that 0.264 gallon = 1L ⇒ we change this in all equations.
8.08 L * A =
a) 8.08 L * 0.264 gal / 8.08 L = 0.264 gal = 1L
b) 8.08 L * 8.08 gallon / 0.264L = (8,08/ 0.264) L/0.264 L = 30.61 / 0.264 = 115.93 L *8.08 L
c) 8.08 L * 8.08 gallon / 1L = (8,08/ 0.264) L/1 L = 30.61 L * 8.08 L
d) 8.08 L * 0.264 L / 1 gallon =8.08 L * 0.264 L / 1 gal
e) 8.08 L * 0.264 gallon / 1L = 8.08 L *1L / 1L = 8.08 L
f) 8.08 L * 1L / 0.264 gallon = 8.08L * 1L / 1L = 8.08 L
The last 2 options are possible ( e and f )
Answer:
Arrhenius acid & Bronsted-Lowry acid
Explanation:
Answer:
Significant figures are a measure of <u><em>precision</em></u>.
Explanation:
The significant figures of a number are those that have a real meaning and, therefore, provide some information. Therefore, the set of digits that are known with certainty in a measure are called significant figures and are the digits of a number considered non-null.
Any experimental measurement is inaccurate and must be expressed with its significant figures.
In this way, significant figures express the precision of a measuring tool.
Answer:
1. False
2. False
3. True
4. False
Explanation:
1. CBr4 is more volatile than CCl4 False
The molecular weight of CBr4 is is greater than the CCl4, therefore it has less tendency to escape to the gas phase. Also, the CBr4 has greater London dispersion forces compared to CCl4 since bromine is a larger atom than chlorine.
2. CBr4 has a higher vapor pressure at the same temperature than CCl4 False
For the same reasons as above, the vapor pressure of CBr4 is smaller than the vapor pressure of CCl4
3. CBr4 has a higher boling point than CCl4 True
Again, CBr4 having a molecular weight greater than CCl4 ( 331 g/mol vs 158.2 g/mol) is heavier and less volatile with a higher boiling point than CCl4.
4. CBr4 has weaker intermolecular forces than CCl4 False
Both molecules are non-polar because the dipole moments in C-Cl and C-Br bonds cancel in the tetrahedron. The only possible molecular forces are of the London dispersion type which are temporary and greater for larger atoms.
