The four (4) functions of water in the body are:

I. Site for many reactions.

II. Transport of nutrients and wastes.

III. Carries heat.

IV. Acts as solvent.

Water can be defined as a liquid molecule that comprises two (2) main chemical elements, which are hydrogen and oxygen in the ratio of two to one (2:1).

Generally, water is considered to be an important and essential chemical molecule that aids in the growth and development of the body of living organisms. The four (4) functions of water in the body of a living organism are:

It is typically a site for many reactions.

It helps in the transportation of nutrients and wastes around the body.

It carries heat from a hot region.

It acts as solvent to dissolve a solute to produce a solution.

what has 4 valence electrons, shows properties of metals and non metals, and has 32 protons in the nucleus of each atom

12345 [234]

Here is your answer

$\bold{Germanium}$

REASON:

Elements which have 4 valence electrons are generally metalloids.

The metalloids show the properties of both metals and non-metals.

We know that,

no. of protons= Atomic number

So,

Atomic no.= 32

Hence,

The element is Germanium which is a metalloid with 4 valence electrons and has 32 protons in nucleus of each atom because it has atomic no. 32

When a solution of sodium hydroxide is mixed with iron (II) chloride, a green precipitate is formed. What is the balanced equati

marshall27 [118]

The balanced chemical equation for the reaction is:

2NaOH(aq) + FeCl₂(aq) --> 2NaCl(aq) + Fe(OH)₂(s)

<h3>What is a chemical equation? </h3>

Chemical equations are representations of chemical reactions using symbols and formula of the reactants and products.

The reactants are located on the left side while the products are located on the right side.

Reactants —> Products

The balancing of chemical equations follows the law of conservation of matter which states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.

<h3>How to write the balanced equation </h3>

Sodium hydroxide => NaOH

Iron (II) chloride => FeCl₂

2NaOH(aq) + FeCl₂(aq) --> 2NaCl(aq) + Fe(OH)₂(s)
