The diatomic molecule H2 has an extremely low boiling point because only weak Vander waals forces are present between the atoms of hydrogen molecule. This weak inter-molecular forces are easily broken when heat is apply resulting in low boiling point.
Answer:
i think so 1 and 3 is the correct answer...................
The answer to your question is B
A kilometer is equal to 1000 meters and a meter is equal to 100 centimeters, so:
1 km = 100000 cm
1 cm = 0,00001 km
Just multiply or divide it by 100000.
The time taken for Hydrogen-3 to decay from 88 g to 11 g is 36.9 years.
<h3>Half-life:</h3>
This can be defined as the time taken for half the sample of a substance to decay or disintegrate
To calculate the time it will take Hydrogen to decay from 88g to 11 g we use the formula below.
Formula:
- R = R'(
)................ Equation 1
Where:
- R = Original sample of Hydrogen
- R' = Sample of Hydrogen left after decay
- T = Total time of decay
- n = Half-life of hydrogen.
From the question,
Given:
- R = 88 g
- R' = 11 g
- n = 12.3 years.
Substitute these values into equation 1
- 88 = 11(
)
Solve for T.
= 88/11
= 8
= 2³................ Equation 2
Equating the base in equation 2 above,
- T/12.3 = 3
- T = 12.3×3
- T = 36.9 years.
Hence, the time taken for Hydrogen-3 to decay from 88 g to 11 g is 36.9 years
