A sample of an ideal gas at 1.00 atm and a volume of 1.87 L was placed in a weighted balloon and dropped into the ocean. As the
Ludmilka [50]

Answer:

Volume of sample after droping into the ocean=0.0234L

Explanation:

As given in the question that gas is idealso we can use ideal gas equation to solve this;

Assuming that temperature is constant;

Lets P_1 and V_1 are the initial gas parameter before dropping into the ocean

and P_2 and V_2 are the final gas parameter after dropping into the ocean

according to boyle 's law pressure is inversly proportional to the volume at constant temperature.

hence,

P_1V_1=P_2V_2

P1=1 atm

V1=1.87L

P2=80atm

V2=?

After putting all values we get;

V2=0.0234L

Volume of sample after droping into the ocean=0.0234L

Identifying Characteristics of Atoms
Anon25 [30]

Explanation:

The number of protons in an atom is the atomic number.

Mass number is the number of protons plus neutrons in an atom.

  Mass number  = number of protons + number of neutrons

Atomic number  = number of protons

Atomic number gives the symbol of the element

Number        Number      Atomic      Mass          Symbol

 Protons       neutrons     Number    Number

     A                    7                 B              15                C

     D                   E                 26             56               F

A, number of protons  = B

 Mass number  = protons + neutrons

          15  = protons + 7

          Protons  = 15 - 7  = 8

Atomic number 8 is for oxygen = C

Atomic number  = number of protons  = D = 26

Number of neutrons ;

          E =    Neutrons  = mass number - protons  = 56  - 26  = 30

Atomic number 26 is for Iron = F

Which law relates to the ideal gas law?​
ella [17]

Answer:

equation (4.16) depends on Boyle's law and Charles' law. The above relates the adjustment in perfect gas volume to the progressions in winning weight and temperature, separately. Moreover, equation (4.16) is alluded to as the condition of state for a perfect gas.

hope it helps:))
