Answer:

Coefficient in front of the NO in the balanced equation - 4

Explanation:

The unbalanced reaction is shown below as:-

NH_3+O_2\rightarrow NO+H_2O

On the left hand side,  

There are 1 nitrogen atom and 3 hydrogen atoms and 3 oxygen atoms

On the right hand side,  

There are 1 nitrogen atom and 2 hydrogen atoms and 2 oxygen atoms

Thus,  

Right side, H_2O must be multiplied by 6 and NO by 4

Left side, O_2 is multiplied by 5 and NH_3 by 4 so to balance the whole reaction.

Thus, the balanced reaction is:-

4NH_3+5O_2\rightarrow 4NO+6H_2O

<u>Coefficient in front of the NO in the balanced equation - 4</u>

A galvanic cell is formed when two metals are immersed in solutions differing in concentration 1 when two different metals are immersed.

<h3>What is galvanic cell?</h3>

A galvanic cell is an electrochemical device that transforms chemically generated free energy into electrical energy. A photogalvanic cell produces photochemical species that react to produce an electrical current when connected to an external circuit.

<h3>How does galvanic cell works?</h3>

In order to create a pathway for the flow of electrons via this wire, the galvanic cell makes use of the ability to split the flow of electrons during the processes of oxidation and reduction, forcing a half-reaction and linking each with a wire.

An electrochemical device known as a galvanic cell converts chemical energy from a spontaneous redox response into electrical energy. It possesses an electrical potential of 1.1 V. The anode, which is a negative plate in galvanic cells, is where oxidation takes place. It is a positive plate where lessening takes place.

Explain the process of fossil fuel formation.
topjm [15]

Explanation:

Fossil fuel is an overall term for covered ignitable geologic stores of natural materials, framed from rotted plants and creatures that have been changed over to unrefined petroleum, coal, flammable gas, or weighty oils by introduction to warmth and weight in the world's outside more than a huge number of years.

The consuming of petroleum products by people is the biggest wellspring of emanations of carbon dioxide, which is one of the ozone depleting substances that permits radiative compelling and adds to an unnatural weather change.

A little bit of hydrocarbon-based powers are biofuels gotten from climatic carbon dioxide, and consequently don't build the net measure of carbon dioxide in the environment.
