What is double substitution

Chemistry
1 answer:
seropon [69]3 years ago
7 0

Answer:

In Tcl the words in a command are always exposed to two layers of interpretation: First, Tcl interprets them and prepares them as arguments to a routine. Second, the routine interprets those arguments according to its own principles. double substitution occurs when Tcl performs substitutions on original command and a routine then performs substitutions on the resulting arguments. Care is required in these cases to avoid errors, including vulnerability to injection attacks.

Vedmedyk [2.9K]

An osmolarity of saline solution is 308 mosmol/L.

m(NaCl) = 9 g; the mass of sodium chloride

V(solution) = 1 L; the volume of the saline solution

n(NaCl) = 9 g ÷ 58.44 g/mol

n(NaCl) = 0.155 mol; the amount of sodium chloride

number of ions = 2

Osmotic concentration (osmolarity) is a measure of how many osmoles of particles of solute it contains per liter.

The osmolarity = n(NaCl) ÷ V(solution)  × 2

The osmolarity = 0.154 mol ÷ 1 L × 2

The osmolarity = 0.154 mol/L × 1000 mmol/m × 2

The osmolarity of the saline solution = 308 mosm/L.

The answer is <span>non-biodegradable and subject to bioaccumulation and/or bioamplification.


DDT (dichlorodiphenyltrichloroethane) is persistent, non-degradable insecticide and organic pollutant readily accumulated to soils and consequently affects organisms.
DDE (</span><span>dichlorodiphenyldichloroethylene) is non-degradable pesticide toxic to birds at the first place.
PCBs (polychlorinated biphenyls) are non-degradable organic compounds  very toxic to the environment.
PBDEs (polybrominated diphenyl ethers) are non-degradable compounds very toxic to environment, even able to affect brains of animals in the development period.</span>
