Explanation:
The given data is as follows.
mass of gasoline = 595.0 lb
volume of gasoline = 
As it is known that density is the amount of mass of a substance divided by its volume.
So, density of gasoline will be as follows.
Density = 
= 
= 42.5 
As, 1 lb = 0.4536 kg and 1 ft = 0.3048 m. Now, putting these values into the above equation (1) as follows.
Density = 42.5
= 
= 680.792 
= 680.8 (approx)
Density of water is 1000 . To measure specific gravity of gasoline, the formula will be as follows.
specific gravity of gasoline = 
= 
= 0.681
Thus, we can conclude that the specific gravity of gasoline is 0.681.

Answer:
A. To focus on only those ions that form the precipitate
Explanation:
Net ionic equations cancel out the ions that appear on both sides of the reaction because they essentially don't participate in the reaction. This is very useful when dealing with redox reactions because are complicated enough without spectator ions being in the way, so they help focus on those ions that actually form the precipitate.
Key Terms
- Spectator Ions: an ion that does not take part in the chemical reaction.
- Net ionic equations: a equation where ions that appear on both sides are canceled out.
- Redox reaction: an oxidation-reduction reaction.
It is a multiply question but your didn't include the choice in this question but the answer in this question is only so3 or s03 only. So3 is the only one that must exist as a set of resonance structures. So3 may be refer to a sulfur trioxide wich means a chemical compound of both trioxide and sulfur.
Answer: The original volume in liters was 0.0707L
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 0.85 atm
= final pressure of gas = 456 mm Hg = 0.60 atm (760mmHg=1atm)
= initial volume of gas = ?
= final volume of gas = 94.0 ml
= initial temperature of gas = 
= final temperature of gas = 
Now put all the given values in the above equation, we get:
(1L=1000ml)
Thus the original volume in liters was 0.0707L
