Answer: 1.56 ATM
Explanation: if we assume temperature is constant, gas obeys
Boyles law pV= constant. Then p1·V1= p2·V2. And V1 = p2V2/p1
= 3.0 atm·0,52 l / 1.0 atm
Its A. because it measures the rate of the decay of the isotope
Answer:
This is a chemical change because it has been lit on fire. When it is lit on fire, the fire has been made, heat has been made, and gasses produced from the fire have also been made. Because this introduces new matter to the pictures, it is a chemical reaction.

<u>Answer:</u> The correct answer is Option c.
<u>Explanation:</u>
Vaporization is defined as the physical process in which liquid particles get converted to gaseous particles.
The value of standard Gibbs free energy is 0 for equilibrium reactions.
To calculate 
for the reaction, we use the equation:
where,
= standard entropy change of vaporization
= standard enthalpy change of vaporization = 30.7 kJ/mol = 30700 J/mol (Conversion factor: 1 kJ = 1000 J)
T = temperature of the reaction = 353.3 K
Putting values in above equation, we get:
Hence, the correct answer is Option c.
