I think the correct answer from the choices listed above is the last option. The family that contains disinfectants is the halogens. This group includes the elements fluorine, chlorine, bromine, iodine, and astatine. Disinfectants are chemical agents that inhibit or kill microorganisms on inanimate objects.
Answer:
A population or group of populations whose members have the potential to interbreed in nature and produce viable, fertile offspring but do not produce viable, fertile offspring with members of other such groups
Explanation:
I used my bio textbook for this but basically only organisms in a group is a population and they can't produce offspring that survive or reproduce unless they are in the same population or populations. Think of like how a liger is a cross of a tiger and a lion and can't reproduce because its not fertile and its from two different species but a lion and a lion can produce a living offspring that can reproduce.

this makes sense to me but im not sure.
Answer:
5.58*10⁻³ moles of gas are in the sample.
Explanation:
The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.
Being 1000 mL equivalent to 1 L, then 125 mL is equal to 0.125 L. Then you can apply the following rule of three: if by STP conditions 22.4 L are occupied by 1 mole, 0.125 L are occupied by how many moles?

aomunt of moles= 5.58*10⁻³ moles
<u><em>5.58*10⁻³ moles of gas are in the sample.</em></u>
To make everything easier to convert so everything universal
