V(rms) = √(3RT/M)
Where R is the molar gas constant with value 8.314 and T is the temperature in Kelvin and M is the molar mass
v(rms F₂) = √(3 x 8.314 x 304 / 38)
v(rms F₂) = 14.1 m/s

v(rms Cl₂) = √(3 x 8.314 x 304 / 71)
v(rms Cl₂) = 10.3 m/s

v(rms Br₂) = √(3 x 8.314 x 304 / 160)
v(rms Br₂) = 6.88 m/s

What is the name for this type of reproduction?​
mario62 [17]

Answer:

----------------------------------------------

Reproduction is defined as the production of individuals of the same species, that is the next generation of the species.

----------------------------------------------

There are basically two types of reproduction - asexual and sexual.

----------------------------------------------

Asexual reproduction involves only one parent and the offspring is

genetically similar to the parent ...

----------------------------------------------

The different types of asexual reproduction are fission, budding, fragmentation, spore formation and vegetative propagation.

----------------------------------------------

Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete (such as a sperm or egg cell) with a single set of chromosomes combines with another to produce a organism composed of cells with two sets of chromosomes .

Asexual reproduction is a type of reproduction which does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from a single cell or from a multicellular organism inherit the genes of that parent.

Your very welcome!!! :) :) :)
