  3. Use forceps, tongs, scoops, or other mechanical devices for removing or retrieving broken glass from the work area or a fume hood.
  4. A dustpan and brush should be used to clean up shards/small pieces of broken glass, Pasteur pipettes, or shards of glass.

Explanation:

Never use broken or chipped glassware. ... Dispose of the glassware in the proper container. Glassware that is chipped, cracked or broken can cause cuts. Material placed in broken or chipped glassware may leak.

Hope this helps!!!!!!!

Forever friend and helper,

The rate at which the concentration of a drug in the bloodstream decreases is proportional to the concentration at any time t. I
Westkost [7]

Answer:

C(t) = C_oe^{-kt}

Explanation:

From the given information:

At any given time (t), let c(t) represent the concentration of the drug present in bloodstream.

Deriving the equation:

\dfrac{dC}{dt} decrease proportionally to Concentration C

i.e

\dfrac{dc}{dt} \alpha - C

\dfrac{dc}{dt} = -k C

\dfrac{dc}{c} = -k dt

\int \dfrac{dc}{c} = -k \int dt

㏑(C) = -kt + λ

where,

λ is the integration constant.

Integrating at t = 0, concentration of blood = Co g/mL

C(0) = Co

㏑(C₀) = 0 + λ

λ = ㏑(C₀)

From ㏑(C) = -kt + λ

㏑(C) = -kt + ㏑C₀

㏑(C)  - ㏑C₀ =  -kt

\dfrac{C}{C_o} = e^{-kt}

C(t) = C_oe^{-kt}

∴

The concentration of drug in blood at any time t is:

C(t) = C_oe^{-kt}
