Answer:
Avogadro's Law; 15.1L
Explanation:
Boyle's Law- Pressure and volume are <u>inversely</u> related, so an increase in pressure= decrease in volume. We see this in the equation P1V1=P2V2.
Charle's Law- Gas expands/increases in volume when temperature increases, so they are <u>proportional</u>. We see this in the formula
.
Guy-Lussac's Law- As temperature increases, pressure increases, so they are <u>proportional</u>. We see this in the formula
.
Avogadro's Law- There are equal amount of volume have an equal amount of moles, so they are proportional. We see this in the formula
.
Plugging in the values based on Avogadro's Law, we'll have:

12.6 = 
12.6 x 1.2 = V2
15.1L =V2
though alchemists were often superstitious, they left a rich legacy of modern chemists. what was their main contribution-
Explanation:
they were the first to preform experiments.
Answer: Kinetic energy is energy possessed by an object in motion. ... Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v².
Answer: idk I have that question too , sorry to get ur hopes up high thinking this was an answer. PERIOTTTT
