Answer:

21H deuterium (D), 31H is tritium (T), 11H is hydrogen

Explanation:

11H: it has the greatest abundance, it has only one proton (it does not have neutrons).

 21H (D): it has a proton and a neutron in its nucleus.

 31H (T): it has a proton and two neutrons in its nucleus.

Remember that isotopes have the same atomic number, but a different mass number (elements in the number of neutrons differed).

Answer:

See below.

Explanation:

They are Hydrogen 1 , Hydrogen 2 (also called deuterium) and Hydrogen 3 (tritium)

Hydrogen has no neutrons in the nucleus while deuterium has 1 and tritium has 2.

Deuterium has been used in the nuclear industry ( as heavy water , deuterium oxide) and  as a compound lithium deuteride in the H bomb. Tritium  is also used as a fuel in nuclear fusion reactions,  and as a radioactive tracer.

The amount of substance present in a certain object with a given half-life in terms of h can be expressed through the equation,

     A(t) = (A(o))(0.5)^(t/h)

where A(t) is the amount of substance after t years and A(o) is the original amount. In this item we are given that A(t)/A(o) is equal to 0.89. Substituting the known values,

     0.89 = (0.5)(t / 5730 years)

The value of t from the equation is 963.34 years.

<em>Answer: 963 years</em>

A 2.4L balloon filled with helium at room temperature 25oC is put into liquid nitrogen
Stels [109]

Answer:

V₂ = 0.62 L

Explanation:

Given data:

Initial volume = 2.4 L

Initial temperature = 25°C

Final temperature = -196°C

Final volume = ?

Solution:

Initial temperature = 25°C (25+273 = 298 K)

Final temperature = -196°C ( -196+273 = 77 K)

The given problem will be solve through the 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 = 2.4 L × 77 K / 298 k

V₂ = 184.8 L.K / 298 K

V₂ = 0.62 L
