Answer:
4-methyl-1-pentyne or 4-methylpent-1-yne
Explanation:
presence of triple bond(alkyne)
Answer: The partial pressure of neon is 173 mmHg
Explanation:
According to Dalton's law, the total pressure is the sum of individual pressures.
Given : 
=total pressure of gases = 490 mm Hg
= partial pressure of Helium = 215 mmHg
= partial pressure of argon = 102 mm Hg
= partial pressure of neon= ?
Thus partial pressure of neon is 173 mmHg
Answer:
First, set the coefficient of C6H14 to 1, then 6CO2 and 7H2O are generated, so there are 9.5 O2, but there can be no fraction, so multiply the coefficient by 2, that is the result
2 19 12 14
Answer:
0.084g/L
Explanation:
First, let us obtain an expression for the density. This is illustrated below:
PV = nRT. (1)
V = nRT/P (2)
But n = Mass(m) /Molar Mass (M)
n = m/M
Substituting the value of n into equation 2
V = nRT/P
V = mRT/MP
Divide both side by m
V/m = RT/MP (3)
Invert equation 3
m/V = MP/RT (4)
But Density = Mass(m) /volume(V)
Density = m/V
Replace m/V with Density in equation 4
m/V = MP/RT
Density = MP/RT
The following data were obtained from the question:
P = 12 Torr
760torr = 1atm
12torr = 12/760 = 0.016atm
T = 80°C = 80 +273 = 353K
R = 0.082atm.L/K /mol
Molar Mass (M) of C10H16O = (12x10) + (16x1) + 16 = 120 + 16 + 16 = 152g/mol
Density =?
Density = MP/RT
Density = (152 x 0.016)/(0.082x353)
Density = 0.084g/L
