Using the Equation: PV=nRT
Where P is the pressure 60 cmHg or 600 mmHg or 600/760= 0.789 atm
V is the volume 125 ml or 0.125 L, n is the number of moles, R is a constant 0.082057, and T is temperature 25 °C or 298 K;
Therefore:
0.789 × 0.125 = n × 0.082057 × 298
n = 0.0987/24.45
= 0.004036 mol
0.004036 mole has a mass of 0.286 g
Hence; 1 mole has a mass of 0.286/0.004036
= 70.8 g /mol
Therefore the molar mass of the gas is 71 g/mol (2 sfg)
Electrolytes conduct electricity because they produce + and – ions in water
C6H12O6 and CH3CH2OH organic no ions
C6H12O6 and HCl sugar and hydrochloric acid
NaOH and HCl yields Na+1 ion and Cl-1 ion to conduct electricity
NaOH and CH3CH2OH
Hope this helps. :)
Hopefully you can understand my writing sorry I'm in the car so I don't have a surface
Answer:
A fast-moving wet slurry consisting of a mixture of water and volcaniclastic debris is termed a lahar
Explanation:
A lahar is a debris flow or mud-flow that consists of a mixture of volcanic material, rock particles and water, flowing typically along a river valley down from a volcano
Lahars can be either from either pyroclastic flows or heavy rainfall after a volcanic eruption
Lahars are hazardous as they can result in destruction, severe damage destroying buildings and some times entire small towns are wiped out. This is more so as they move silently and very fast down to the valleys
