For the reaction PCl5(g) + heat PCl3(g) + Cl2(g), what will happen when the pressure is increased? There will not be a shift in
Tamiku [17]
When the pressure is increased, the equilibrium will shift to the left to offset the pressure increase. Equilibrium shifting to the left side is favored because the left side has fewer moles of gas than the number of moles of gas on the right-hand side and because it exerts less pressure. Therefore, the answer is there will be a shift toward the reactants.

The half-life of Co-59 is 35 days. How much of a 610.0-gram sample will remain after 140 days?
vitfil [10]

Answer:

Amount left after 140 days is 38.125 g.

Explanation:

Given data:

Half life of Co-59 = 35 days

Total mass of sample = 610.0 g

Sample remain after 140 days = ?

Solution:

Number of half lives passes during 140 days:

Number of half lives  = T elapsed / Half lives

Number of half lives  = 140 days / 35 days

Number of half lives  = 4

Amount left:

At time zero = 610 g

At first half life = 610 g/2 = 305 g

At second half life = 305 g/2 = 152.5 g

At 3rd half life = 152.5 g/2 = 76.25 g

At 4th half life = 76.25 g /2 =38.125 g

Amount left after 140 days is 38.125 g.

Each astronaut produces 8.8 x 10^2 grams of CO2 per day that must be removed from the air on the shuttle if typical shuttle miss
iris [78.8K]
M₀(CO₂)=8.8*10² g
m(LiOH)=3.5*10⁴ g
x=9 d

2LiOH + CO₂ = Li₂CO₃ + H₂O

m(CO₂)=M(CO₂)m(LiOH)/2M(LiOH)

N=m(CO₂)/xm₀(CO₂)=M(CO₂)m(LiOH)/{2M(LiOH)xm₀(CO₂)}

N=44.01*3.5*10⁴/{2*23.95*9*8.8*10²}=4

The maximum number of people is 4.

It is also possible the reaction:
Li₂CO₃ + CO₂ + H₂O = 2LiHCO₃
