Which type of test helps forensic scientists to narrow down the possibilities of what drug a substance may be?
kobusy [5.1K]

The right answer is screening test.

In medicine, screening consists of looking for one or more diseases or abnormalities known as "at risk" in individuals of a given population.

These investigations are followed or not by medical consultations, clinical examinations and treatments.

In addition, screening is a preliminary procedure (test or examination) to detect one or more characteristic signs or symptoms of a disease or syndrome and potentially leading to further investigation.

Consider these reactions:
Virty [35]

511.2 grams of chlorine gas consumed (with excess H-) when

1,342.0 kJ of energy is released from the system.

<h3></h3><h3>What is an exothermic reaction?</h3>

In thermochemistry, an exothermic reaction is a "reaction for which the overall standard enthalpy change ΔH⚬ is negative."

Given that 1 mole of chlorine releases -184.6 energy.

Then, we have to find the number of moles of chlorine when 1,342.0 kJ of energy is released from the system.

So, calculating number of moles of chlorine.

Moles = \frac{-1,342.0 \;kJ}{-184.6\;kJ}

Moles = 7.2 mole

Now, calculating number mass of chlorine.

\rm Moles=\rm\frac{Mass}{Molar \;mass}

Mass =  7.2 mole x 71 g/mole

Mass = 511.2 gram
