Chemistry

Answer:

0.84ppm

Explanation:

  Mass of solute  = 3.8 x 10⁻⁴g

  Mass of solution  = 450g

Unknown is the concentration in ppm; parts per million

The parts per million is one of the units of representing small concentration of solutes in a solution.

Solutes are the substances dissolving in another to give solution.

Here the concentration is expressed in a million units.

Concentration in ppm  = \frac{mass of solute}{mass of solution}  x 10⁶

                                     = \frac{3.8 x 10^{-4} }{450}   x 10⁶

                                     = 0.84ppm

Formula semidesarrollada de los hidrocarburos aromáticos de 1 a 10 átomos de carbono
Tju [1.3M]

Answer:

El principal componente del gas natural es también el hidrocarburo más simple: el metano. Este compuesto está formado por un átomo de carbono y cuatro átomos de hidrógeno y se representa de dos formas:

El hidrocarburo que le sigue en simplicidad es aquel que está constituido por dos átomos de carbono. Su fórmula condensada es C2H6 y se le conoce como etano.

Si se continúan colocando átomos de carbono con enlaces sencillos entre ellos e hidrógenos en los enlaces libres, se crean largas cadenas de compuestos. Al etano le sigue el propano (C2H8) y a éste, el butano (C4H10). Todos estos compuestos forman parte de la familia de los alcanos, y sus nombres terminan con el sufijo –ano para indicar que pertenecen a la misma familia.

notsponge [240]

Blood should NOT be stored in an airtight container

<h3>Explanation:</h3>

We can store blood by dried it on a swab. To collect the dried blood, we should moisten a sterile cotton swab using distilled water or tap water, then shake the swab to remove excess water. Gently swab the stain with the moistened swab tip until the swab thoroughly absorbs the blood.

We can store blood also in the dried blood stains and as a scraping. The fresh collected blood, dried blood stains, wet blood stains are contained the DNA.

Airtight containers are the plastic used to make the durable containers and it is free from BPA and has been graded to be safe to be used with food supplies. ​The lid of this container has an innovative airtight mechanism which helps to maintain the airtight environment inside the container.

According to book "Criminal Investigation" By Ronald F. Becker on page 114, the airtight containers can cause condensation of moisture within the container and result in bacteria that can destroy, alter or contaminate the blood.

Blood components should be stored at temperatures storage in accordance with the requirements listed. Failure to follow correct storage requirements result in decreased transfusion efficacy
