Each astronaut produces 8.8 x 10^2 g CO2 per day that must be removed from the air on the shuttle. If a typical shuttle mission is 9 days, and the shuttle can carry 3.50 x 10^4 g LiOH, what is the maximum number of people the shuttle can carry for one mission

The answer to this would be:

The shuttle can carry a maximum of 4 astronauts for one mission.

2 LiOH + CO2 -----> Li2CO3 + H2O

(3.50 × 10^4 g LiOH) (1 mol LiOH/ 24 g LiOH) ( 1 mol CO2 / 2 mol LiOH) ( 44 g CO2 /1 mol CO2) = 32, 083.33 g CO2

32, 083.33 g / 9 (8.8 × 10^2) = 4

Why does warm soda go flat faster than cold soda
Solution 1
The gas comes out more quickly when the can is warm because carbon dioxide is less soluble in warmer liquids.
Solution 2
Carbonation lasts longer in colder environments.
A polar covalent bond will form between which two atoms? a. beryllium and fluorine (group 1 and group 7) b. hydrogen and chlorine (group 7) c. sodium and oxygen (group 1 and group 6) d. fluorine and fluorine (group 7)
Solution 1

Types of Bonds can be predicted by calculating the difference in electronegativity.

If, Electronegativity difference is,


                Less than 0.4 then it is Non Polar Covalent


                Between 0.4 and 1.7 then it is Polar Covalent 


                Greater than 1.7 then it is Ionic


For Be and F,

                    E.N of Fluorine          =   3.98

                    E.N of Beryllium        =   1.57


                    E.N Difference                2.41          (Ionic Bond)

For H and Cl,

                    E.N of Chorine           =   3.16

                    E.N of Hydrogen        =   2.20


                    E.N Difference                0.96          (Polar Covalent Bond)

For Na and O,

                    E.N of Oxygen          =   3.44

                    E.N of Sodium          =   0.93


                    E.N Difference                2.51          (Ionic Bond)

For F and F,

                    E.N of Fluorine          =   3.98

                    E.N of Fluorine          =   3.98

Overall mineral crystal size depends on how fast a solution _____.
Solution 1

In overall, the size of the mineral crystal depends on how fast a solution cools down. More time that is spent during cooling creates larger crystals because of the free movement of the constituent of mineral isotopes in a somewhat liquid solution.

Solution 1
Natural  gas  is primarily composed of   methane (CH4)

atural  gas  is a naturally  occurring  hydrocarbon  mixture  which  is  primarily  composed of Methane(CH4),  but it  also  contains ethane,propane and  heavier hydrocarbon. In addition  it  contain small amount  of nitrogen, carbon dioxide,hydrogen sulfide and traces amount of water.

It is necessary to have a 40% antifreeze solution in the radiator of a certain car. the radiator now has 70 liters of 20% solution. how many liters of this should be drained and replaced with 100% antifreeze to get the desired strength?
Solution 1
The answer is : 17.5 liters drained and replaced by 17.5 liters of 100% solution. 
x = amount drained and replaced
(70-x) = remaining amount of 20% solution
.20(70-x) + 1.00(x) = .40(70)
14 - .2x + 1x = 28
1x - .2x = 28 - 14
.8x = 14
x = 14/.8
x= 17,5 ( 17.5 liters drained and replaced by 17.5 liters of 100% solution)

Solution 2


17.5 litres removed and 17.5 litres of pure antifreeze added


Let k equal the amount of the solution to be removed

amount of antifreeze to be added

0.2(70 - x) + x = 0.4(70)

14 - 0.2x +x = 28

0.8x = 28 -14

x = 14/0.8 = 17.5

x = 17.5 litres removed and 17.5 litres of pure antifreeze added

How many kilojoules are required to convert 115.0 g of ice at 0.0 ∘c to liquid water at 32 ∘c? the heat of fusion of water is 334 j/g, and the heat capacity of water is 4.184 j/g ∘c?
Solution 1
The answer is 53.8 kJ.
Solution:There are two major steps in converting ice to liquid water. It begins with a phase change when ice melts at 0.0°C, and then a temperature change when the liquid water rises in temperature from zero to 32°C.
The amount of heat involved with the phase change melting is given by
     q = (mass of water) (ΔHfus)
        = (115.0 g)(334 J/g) 
        = 38410 J = 38.41 kJ
The amount of heat involved with temperature change is 
     q = mcΔT
        = (115.0g)(4.184J/g°C)(32°C - 0.0°C)
        = 15397.12 J = 15.39712 kJ
Summing up the two values gives the total heat required to convert ice to liquid water:
     q = 38.41 kJ + 15.39712 kJ= 53.8 kJ
0.50 g Al equals how many moles
Solution 1

Answer: The number of moles of 0.50 g Aluminium is 0.0185 moles.


To calculate the number of moles, we use the formula:

Moles=\frac{\text{Given mass}}{\text{Molar mass}}

In the given question:

Given mass of Aluminium = 0.50 g

Molar mass of Aluminium = 27 g/mol

Putting values in above equation, we get:

\text{Moles of Aluminium}=\frac{0.50g}{27g/mol}=0.0185moles

Hence, the number of moles of 0.50 g of Aluminium is 0.0185 moles.

Solution 2
Molar mass of aluminum ( Al ) = 26.98 g/mol

n = m / M

n = 0.50  / 26.98 

n = 0.01853 moles

hope this helps!
