3 O2 + CS2 = CO2 + 2 SO2
That is the balanced equation!
I may be late lol!!
Hope it helps
Answer:
mass is the amount of substance contained in matter while volume is the space occupied by matter
in other words , mass talks about how heavy a body is while volume deals with the space covered by a 3- dimensional body. note : A 2- dimensional body can't occupy volume
Answer:
0.0630
Explanation:
The molar mass of urea = 60 g/mol
we all know that:
Then; the number of moles of urea
=
= 0.0667 mol
Similarly; the number of moles of methanol
=
= 0.9988 mol
The total number of moles = (0.0667 + 0.9988) mol
= 1.0655 mol
Finally,the mole fraction of urea =
=
= 0.0630
The answer is B because atoms and molecules are too small to count one by one
.3999 moles
The ideal gas law: PV = nRT
155 degrees Celsius = 428 Kelvins
n = PV/RT
n = 2.80 atm x 5.00 L/0.0821 (gas constant) x 428 K
= 0.398 moles
