Explanation and answer:
The molar volume of a gas is 22.4 L at 0 deg. C.
So the molar mass of the gas is, by proportion,
0.16 g * (22400 mL)/(240 mL) = 14.93 g
The molar mass of (CH4)n = 12+4(1) = 16.
So n = 15.93/16 = 1, or the molecular formula is CH4.
Note: The temperature at which the volume was observed was not given. If 240 cm^3 was observed at 20 deg.C, then the volume at 0 deg.C would be
V=240*(273+0)/(273+20) = 223.6
The molar mass = 0.16*22400/(223.6) = 16.03
which gives n = 16/16.03 = 1 again, but more accurately.
Answer:
3750 cm.
Explanation:
You multiply the three side measurements to find the volume.
25cm·10cm·15cm
375cm·10cm
3750 cm.

Answer:
Fluorine
Explanation:
Fluorine is the most electronegative element because it has 5 electrons in it's 2P shell.
Answer:
there are several types of Kinetic Energy: radiant, thermal, sound, electrical and mechanical.
Explanation:
Radiant energy is energy that travels in waves Its given off by electromagnetic radiation
Thermal energy results in an object or a system having a temperature that can be measured but it has to have motion
Sound a mechanical wave and as such consists physically in oscillatory elastic compression and in oscillatory displacement of a fluid
Electrical When you let go of that ball and let it fall, the potential energy converts into kinetic energy
Mechanical is the result of its motion
