Nitric acid is often manufactured from the atmospheric gases nitrogen and oxygen, plus hydrogen prepared by reforming of natural

hoa [83]

Answer: The net chemical equation is given below.

Explanation:

To determine the net chemical equation, we will look into the intermediate steps:

Step 1: Formation of ammonia from hydrogen and nitrogen gas.

$N_2(g)+3H_2(g)\rightarrow 2NH_3(g)$ ......(1)

Step 2: Formation of nitric acid from ammonia and oxygen gas.

$NH_3(g)+2O_2(g)\rightarrow HNO_3(g)+H_2O(g)$ .....(2)

The net chemical equation for the formation of nitric acid from hydrogen gas, nitrogen gas and oxygen gas follows by adding both the equations, we get:

$N_2(g)+2O_2(g)+3H_2(g)\rightarrow HNO_3(g)+H_2O(g)+NH_3(g)$

By Stoichiometry of the reaction:

1 mole of hydrogen gas reacts with 2 moles of oxygen gas and 3 moles of hydrogen gas to produce 1 mole of nitric acid, 1 mole of water and 1 mole of ammonia.

Hence, the net chemical equation is given below.

Which part of the amino acid helps identify features that differentiate one amino acid from another

Natasha_Volkova [10]

The part of the amino acid which helps to identify features that differentiate one amino acid from another is the SIDE CHAIN OF EACH AMINO ACID.
Amino acids are made up of five basic parts, these are:
1. A central carbon atom
2. A hydrogen atom
3. An amino group
4. A carboxyl group and
5. A R group, also known as a side chain.
The side chain distinguishes one amino acid from the other; different amino acids have different side chains.

____________ use cleaning solutions that eventually become spent and must be disposed of properly.

Elanso [62]

The answer is- Part washers use cleaning solutions that eventually become spent and must be disposed of properly.

Cleaning solutions: Cleaning solution is a liquid solvent or solution used to clean the working surfaces and the parts of a machine.

What type of cleaning solution is Part washers?

Parts washers are mechanical devices that are designed to be cleaned to remove debris, dirt, oil, paint, and other substances that could potentially contaminate parts to prepare them for assembly, packaging, or even painting.

They are basically used to clean parts to make them ready for functional use.

Cleaning solutions for washing used parts are considered a special waste because they can be hazardous waste and are waste from an industrial process.

Used solvents are almost always hazardous waste. Both solvent and aqueous parts washers produce a sludge that is usually hazardous because it contains toxic metals and solvents from the parts being cleaned.

Absorbents used to wipe parts after washing are also dangerous if they contain toxic metals in concentrations exceeding regulatory limits or listed hazardous solvents, and used oil may also contain hazardous waste.

Thus, these cleaning solutions must be disposed of properly.
