Answer:
2.13L
Explanation:
first you must find the amount(mols) of HCl in the solution. then you can use that to find the volume of the solution.
we know the:
mass m = 9.35g
molar mass M = 1 + 35.5=36.5 g/mol ( <em><u>check</u></em><em><u> </u></em><em><u>pe</u></em><em><u>riodic</u></em><em><u> </u></em><em><u>table</u></em><em><u> </u></em>)
concentration c = 0.120 mol/L
amount ( mols) of HCl:
n= m/M
n(HCl) = 9.35/36.5
= 0.2561644 mol
concentration of HCl in solution:
n= cV
V(HCl) = n/c
= 0.2561644/0.120
= 2.1347
= 2.13 L (<em>3sf</em><em>)</em><em> </em>
Carbon monoxide poisoning has certain symptoms in order to detect its presence but development of mees lines on the figer and toe nails does not include on its symptoms.

Hope this helps. pls mark me brainliest :)
Answer:
its called TAXON0MY
Explanation:
they are classified in eight steps namely doma!n, k!ngdom, phylum, class, order, family, genus, and spec!es
but sometimes we do not include doma!n
if you want to name an organism you use both the genus group and the spec!es group
Example:
The scientific name for humans like us is h0m0 sap!ens
H0m0- This is our genus group
sap!ens- This is our spec!es group
