Convert 150 kPa to atmospheres. *
lakkis [162]

Answer: 1.48 atmosphere

Explanation:

Pressure in kilopascal = 150

Pressure in atmosphere = ?

Recall that 1 atmosphere = 101.325 kilopascal

Hence, 1 atm = 101.325 kPa

Z atm = 150 kPa

To get the value of Z, cross multiply

150 kPa x 1 atm = 101.325 kPa x Z

150 kPa•atm = 101.325 kPa•Z

Divide both sides by 101.325 kPa

150 kPa•atm/101.325 kPa = 101.325 kPa•Z/101.325 kPa

1.48 atm = Z

Thus, 150 kPa is equivalent to 1.48 atmospheres

A container holds 100.0 mL of nitrogen at 21° C and a pressure of 736 mm Hg. What will be its volume if the temperature increase
devlian [24]

Answer:

V₂ = 104.76 mL

Explanation:

Given data:

Initial volume = 100.0 mL

Initial temperature = 21°C (21 + 273.15 K = 294.15 K)

Final temperature = 35°C (35 + 273.15 K = 308.15 k)

Final volume = ?

Solution:

Charles Law:

According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.

Mathematical expression:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume  

T₂ = Final temperature

Now we will put the values in formula.

V₁/T₁ = V₂/T₂

V₂ = V₁T₂/T₁  

V₂ =100.0 mL × 308.15 K / 294.15 K

V₂ = 30815 mL.K /294.15 K

V₂ = 104.76 mL

If an element A has 3 shells and has 3 valence electrons, write formulas for the following:
Ilya [14]

Electron configuration

an element A has 3 shells and has 3 valence electrons

so electron configuration of A: 1s², 2s², 2p⁶, 3s², 3p¹

will tend to lose 3 electron to form a cation: A³⁺

a. Nitrate of A

A(NO₃)₃

b. Chloride of A

ACl₃

c. Oxide of A

A₂O₃

Which among the following statements is FALSE? Group of answer choices None of the above A liquid has a definite volume; but it
Vesna [10]

Answer: None of the above statements is false.

Explanation:

In a solid substance, particles are closely held together due to which a solid substance has definite shape and volume. Therefore, solids are also incompressible in nature.

In liquids, the molecules are slightly away from each other due to which they can slide past each other. Hence, liquids do not have a fixed shape but they have a definite volume. Liquids are also incompressible in nature.

In gases, the particles are held by Vander waal forces due to which they move rapidly from one place to another. Hence, gases are highly compressible in nature.

Thus, we can conclude that none of the given statements are false.

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
Sever21 [200]
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
