Answer:
Explanation:
If this is a double replacement reaction or salt metathesis, then I have taken the liberty of including the symbol representing an aqueous solution, (aq), to the formulas in the equation written as CuCl2(aq)+2NaNO3(aq)→Cu(NO3)2(aq)+2NaCl(aq).
In order for a double replacement reaction to occur, one of the products must be a solid precipitate (a salt), an insoluble gas, or water. Since all species are in aqueous solution, none of these products occur, which means there is no reaction. The result is an aqueous solution containing Cu2+, Cl−, Na+, and NO3− ions.
The equation should be written as CuCl2(aq)+2NaNO3(aq)→No Reaction

A quantitative observation must be a measurement of some sort. (Something including numbers). Qualitative, on the other hand, is when you are using words to describe what has happened.
Answer: 16.7 gallon
Explanation:
Given: The car can drive 30.3 miles when 1 gallon of gasoline is used.
Distance covered = 506.3 miles
Thus for 30.3 miles, the amount of gasoline used= 1 gallon
For 506.3 miles, the amount of gasoline used=
Thus the amount of gasoline used is 16.7 gallons.
