I believe the correct answer from the choices listed above is the third option. Water is necessary for living organisms because all organisms need water to transport chemicals into their cells. Hope this answers the question. Have a nice day.

The answer is: All organisms need water to transport chemicals into their cells.

For example, supplies the body with oxygen and nutrients, and picks up carbon dioxide wastes.

The blood transports:

1) oxygen from the lungs to the cells of the body.

2) carbon(IV) oxide from metabolism to the lungs, where it is exhaled.

3) nutrients, transports hormones and removes waste products.

The compound FeCl3 is made of one atom and three atoms of chlorine

explanation

FeCl3 is made up of two elements.

that is iron with Fe chemical symbol and chlorine with Cl chemical symbol.

There are 3 atoms of chlorine in FeCl3 because the subscript in front of Cl in FeCl3 is 3.

Answer:

The top layer is the Aqueous layer, and the benzoic acid is contained in the non-aqueous layer/oil phase.

Explanation:

A separating funnel is a very important piece of laboratory glassware that is used to separate the components of liquid-liquid mixtures which are immiscible. This technique is used in the extraction of the components of mixtures.

The liquids separate into two phases. The separation is based on the differences in the liquids' densities, where the denser liquid settles below and the lower density liquid stays afloat. Liquids used for this kind of separation are usually different liquids, one is the aqueous layer and the other, a non-aqueous layer.

Partition coefficient or distribution coefficient is defined as the ratio of the concentrations of a compound in two immiscible solvents at equilibrium.

Organic solvents (except halogenated organic compounds) with densities greater than that of water i.e 1g/mL ( usually called the oil phase) settle at the bottom of the aqueous phase.

Benzoic acid. will settle at the bottom layer ( i.e the lower phase).

Ray Of Light [21]

Answer:

El volumen del gas era 12.95 L

Explanation:

Se relaciona la presión y el volumen mediante la ley de Boyle, que dice:

“El volumen ocupado por una determinada masa gaseosa a temperatura constante, es inversamente proporcional a la presión”

La ley de Boyle se expresa matemáticamente como: P*V=k

Por otro lado, la Ley de Charles consiste en la relación que existe entre el volumen y la temperatura absoluta de una cierta cantidad de gas ideal, el cual se mantiene a una presión constante. Esta ley dice que cuando la cantidad de gas y de presión se mantienen constantes, el cociente que existe entre el volumen y la temperatura siempre tendrán el mismo valor:

$\frac{V}{T}=k$

Por último, la Ley de Gay Lussac dice que la temperatura absoluta y la presión son directamente proporcionales. Es decir, cuando se mantiene todo lo demás constante, mientras suba la temperatura de un gas subirá también su presión. Y mientras la temperatura del gas baje, lo mismo ocurrirá con la presión:

$\frac{P}{T}=k$
