Answer is number 4.
The above diagram shows a part of our solar system.The planet which is very close to the sun is Mercury. Hence, No.1 is Mercury and 2 and 3 are Venus and Earth respectively. Moon is an astronomical body which orbit planet Earth. Hence moon should be shown near to the planet Earth.
Answer:
gas
Explanation:
the liquid evaporates and has heat is given to the particles, their kinetic energy increases and they bounce off one another
First let us compute for the number of moles of butane
(molar mass = 58.12 g/mol)
number of moles = 145 g / (58.12 g/mol) = 2.49 mol
<span>We use the ideal
gas equation to calculate the volume:</span>
<span> V = n R T / P</span>
V = 2.49 mol * 62.36367 L torr / mol K * 308.15 K / 745
torr
<span>V = 64.35 L</span>
the cathode is where reduction occurs!
