What do you mean? Is this for anyone stuck on the same question cause I don’t think that’s how it works lol
Answer:
C. 101.2 L
Explanation:
N2 + H2= NH3
Balancing it,
N2 + 3 H2 = 2.NH3
(1 mol) (3 mol) (2 mol)
which means
1 molecule of nitrogen reacts with 3 molecule of hydrogen to form ammonia.
Likewise,
50.6 l of nitrogen reacts with 50.6 × 3= 151.8 l of hydrogrn to form 50.6 × 2= 101.2 l of ammonia.
Answer:
Δ should be 0.1009
Explanation:
The change in the units volume when temperature change can be expressed as:
∆v = v0Δ
with v0 = the initial volume
with = the volumetric temperature expansion coefficient
with Δ = the change of temperature.
To calculate the final volume vf we'll get:
v = v0 + ∆ = v0(1 + Δ)
The liquid just begins to spill out if v(benzene) = :
v()(1 + Δ) = = v() (1 + Δ)
(v(cavity)-v(benzene))/(((benzene) -(copper)) = Δ
((1.22*10^-3)-(1.1*10^-3))/((1240*10^-6)-(51*10^-6)) = Δ
Δ = 0.1009
Δ should be 0.1009
The ratio of the diffusion rate of Cl2 and O2 is 1.5
calculation
rate of diffusion Cl2/ rate of diffusion O2 =√ molar mass of Cl2/ molar mass of O2
molar mass of Cl2 = 35.5 x2 = 71 g/mol
molar mass O2 = 16 x2 =32g/mol
that is rate of diffusion Cl2/ rate of diffusion of O2 =√ 71/ 32= 1.5
