1 answer:

4 0

Las disoluciones son fundamentales para que se lleven a cabo las reacciones químicas que sustentan la vida. Esta es una mezcla de dos o más sustancias.

<h3>Disoluciones</h3>

Una disolución se refiere a una mezcla entre dos o más sustancias puras que da lugar a una mezcla homogénea de las mismas.

Una disolución está compuesta por al menos una sustancia conocida como disolvente (por ejemplo, agua) y al menos susutancia conocida como soluto (por ejemplo, sal).

Las disoluciones son fundamentales para una gran variedad de procesos biológicos requeridos para sustentar la vida y las reacciones metabólicas asociadas a estos procesos.

Complete and balance the molecular equation for the reaction of aqueous sodium sulfate, Na2SO4, and aqueous barium nitrate, Ba(N

Rina8888 [55]

Answer:

1. The balanced molecular equation is given below:

Na2SO4(aq) + Ba(NO3)2(aq) —> BaSO4(s) + 2NaNO3(aq)

2. The net ionic equation is given below:

SO4^2-(aq) + Ba^2+(aq) —> BaSO4(s)

Explanation:

1. The balanced molecular equation

Na2SO4(aq) + Ba(NO3)2(aq) —> BaSO4(s) + NaNO3(aq)

The above equation can be balance as follow:

Na2SO4(aq) + Ba(NO3)2(aq) —> BaSO4(s) + NaNO3(aq)

There are 2 atoms of Na on the left side and 1 atom on the right side. It can be balance by putting 2 in front of NaNO3 as shown below:

Na2SO4(aq) + Ba(NO3)2(aq) —> BaSO4(s) + 2NaNO3(aq)

Now, the equation is balanced.

2. The bal net ionic equation.

This can be obtained as follow:

Na2SO4(aq) + Ba(NO3)2(aq) —>

In solution, Na2SO4 and Ba(NO3)2 will dissociate as follow:

Na2SO4(aq) —> 2Na^+(aq) + SO4^2-(aq)

Ba(NO3)2(aq) —> Ba^2+(aq) + 2NO3^-(aq)

Na2SO4(aq) + Ba(NO3)2(aq) —>

2Na^+(aq) + SO4^2-(aq) + Ba^2+(aq) + 2NO3^-(aq) —> BaSO4(s) + 2Na^+(aq) + 2NO3^-(aq)

Cancel the spectator ions i.e Na^+ and NO3^- to obtain the net ionic equation.

SO4^2-(aq) + Ba^2+(aq) —> BaSO4(s)

low level waste

Explanation:

Low level wastes are nuclear wastes generated from hospitals and industries as well as the nuclear fuel cycle, and is comprised of paper, rags, tools, clothing, filters, etc., which contain small amounts of mostly short-lived radioactivity.

Low level wastes are typically radioactive in nature and are difficult to dispose.
They originate from radioactive processes in the hospital and nuclear reactors.
There has been growing concerns about the safe disposal of radioactive wastes over the years.

They are made up of materials with short lived radioactivity.

What coefficients can be used to balance the following equation

zheka24 [161]

The coefficient that can be used to balanced the given equation are 3, 2, 6, 1

<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 balance the equation </h3>

K₂CO₃ + FeCl₃ -> KCl + Fe₂(CO₃)₃

There are 3 atoms of C on the right side and 1 on the left side. It can be balanced by writing 3 before K₂CO₃ as shown below:

3K₂CO₃ + FeCl₃ -> KCl + Fe₂(CO₃)₃

There are 6 atoms of K on the left side and 1 on the right side. it can be balanced by writing 6 before KCl as shown below:

3K₂CO₃ + FeCl₃ -> 6KCl + Fe₂(CO₃)₃

There are 6 atoms of Cl on the right side and 3 on the left. It can be balanced by writing 2 before FeCl₃ as shown below:

3K₂CO₃ + 2FeCl₃ -> 6KCl + Fe₂(CO₃)₃

Now the equation is balanced.

Thus, the coefficients are; 3, 2, 6, 1

draw the lewis structure, including unshared pairs, of the following molecule. carbon has four bonds in the compound. propane (c

SIZIF [17.4K]

There are three carbon and 8 hydrogen present in propane molecule. The Lewis structure of propane is shown as:

Three molecules of such carbon atoms bound to eight molecules with hydrogen atoms make up the organic complex propane molecule.

It is known that carbon has 4 valence electrons and hydrogen has one valence electron. Carbon needs 4 extra electrons to complete its octet hence, it will share its electrons with with 4 hydrogen atom and complete its octet.

Carbon will be formed 4 bond . Three bond with hydrogen and one bond with carbon atom.
