Answer:
Physical change
Explanation:
The molecules are being rearranged as the water changes phases from liquid to gas, but this doesn't change the chemical structure of the water.
The energy produced in the burning of gasoline = 45 kJ/g. So, amount of energy produced by burning 48 L gasoline = 45 kJ/g×36960 g = 1663200 kJ.
The partial pressure of the N2H4 gas is 1.50 atm.
<h3>Dalton's law of partial pressure</h3>
From the Dalton's law of partial pressure, the total pressure of a mixture of gases is the sum of the individual partial pressures of all the gases present in the mixture.
We have the following;
C2H2F4 = 3.00 atm
N2H4 = c
Total pressure = 3.00 atm + 1.50 atm = 4.50 atm
Hence, the partial pressure of the N2H4 is N2H4.

A salt would be left over. For example, if you reacted NaOH with HCl, your products would be NaCl, a salt, and water.
