what is the symbol of an ion having 17 protons and 18 electrons

Geographic features such as mountain ranges, coastlines, and human-modified land can cause air pollutants to concentrate or disperse in a given area. However, the types and quantities of pollutants in the air have a far greater impact on air quality.

A pollutant is a substance or energy introduced into the environment that has unintended consequences or reduces the utility of a resource. Pollutants that can be both naturally occurring and anthropogenic in origin include carbon monoxide, lead, nitrogen oxides, ground-level ozone, particle pollution (also known as particulate matter), and sulfur oxides.

Elevated atmospheric pressure and circulation changes may affect the movement of air pollutants and air pollution concentrations at a given location. Pollutants move through the atmosphere due to transport, dispersion, and deposition. The movement caused by a time-averaged wind flow is referred to as transport. Dispersion is caused by local turbulence, or motions that last less than the time required to average the transport.

We can change a molecule into a series of one or more elements by breaking down the chemical bonds that connect atoms in the molecule.

The chemical bonds of a molecule can be defined as the different types of attractive forces that link atoms in a molecule, which include, for example, covalent bonds, ionic bonds, hydrogen bonding, metallic bonding, etc.

Therefore, with this data, we can see that we have to break the chemical bonds of a molecule in order to separate molecules into their simplest constituents, i.e., atoms.

With an 18-carbon backbone, stearic acid is a saturated long-chain fatty acid.

What is Stearic Acid?

With an 18-carbon chain, stearic acid is a saturated fatty acid. Octadecanoic acid is the substance's IUPAC name. It has the chemical formula C₁₇H₃₅CO₂H and is a waxy solid. The word "stear," which means tallow in Greek, is where it gets its name. Stearates are the names for the salts and esters of stearic acid. The second most prevalent saturated fatty acid in nature after palmitic acid is stearic acid, which serves as its ester. [11] Stearin is the triglyceride produced when three molecules of stearic acid are combined.

Explanation:

Animal fat contains more stearic acid than vegetable fat does. The foods cocoa butter and shea butter are the notable exceptions because they contain stearic acid (as a triglyceride).

In terms of its biosynthesis, acetyl-CoA contributes two-carbon building blocks to the fatty acid synthesis machinery, which converts carbohydrates into stearic acid.

The triglycerides in fats and oils are saponified with hot water to produce stearic acid. After that, the resulting mixture is distillated.

In a positive ion, the number of protons remains the same as the original atom, but there are fewer electrons. On the other hand, in a negative ion, the number of protons also remains the same, but there are more electrons.

In a positive ion, the number of protons exceeds the number of electrons and this results in an overall positive charge because protons carry a positive charge (+1) while electrons carry a negative charge (-1).

In a negative ion, the number of electrons exceeds the number of protons and this results in an overall negative charge because there are more negatively charged electrons (-1) than positively charged protons (+1).

So, it can be concluded that positive ion has fewer electrons as compared to protons whereas negative ion has more electrons as compared to protons.

Some metals are very reactive while other metals are less reactive or unreactive. When a more reactive metal is added to the solution of a less reactive metal, then the more reactive displaces the less reactive metal from its solution is known as a displacement reaction.

The general form of a single displacement reaction can be represented as:

Answer:

The theory for metallic bonding explains conductivity by stating that metals have delocalized electrons that are free to move throughout the metal lattice. When an electric field is applied to a metal, these delocalized electrons move in response to the field, creating an electric current. Since these electrons are not bound to a particular atom, they are free to move throughout the metal, which allows for the high electrical conductivity that is characteristic of metals.

Explanation:

he specific heat of a 26 grams sample of metal at 82.25 degrees is 0.971 J/g°C.

Given that

Initial temperature of liquid water = 24.0°C

Final temperature of water = 28.34°C

Final temperature of metal = 28.34°C

Mass of water = 75.0 grams

Mass of metal = 26.0 grams

Specific heat capacity of water = 4.18 J/g°C

To find the specific heat of the metal:

Mathematically, heat capacity or quantity of heat is given by the formula;

Where:

Q represents the quantity of heat.

m represents the mass of an object.

c represents the specific heat capacity.

∅ represents the change in temperature.

Heat lost by water = Heat gained by metal.

75 ( 4.18) ( 28.34 - 24) = 26c (82.25 - 28.34)

313.5 ( 4.34) = 26 ( 53.91) c

1360.59 = 1401.66 c

The standard deviation and per cent relative standard deviation, which represent the uncertainty in the molarity of your EDTA titrant.

To calculate the uncertainty in the molarity of your EDTA titrant, we need some information about the measurements taken during the titration process. However, since the information is not provided, I will give you a general step-by-step guide to finding the uncertainty in molarity:
1. Record the volume measurements (in mL) for each titration trial.
2. Calculate the molarity of the EDTA titrant for each trial using the balanced equation of the reaction and the known molarity and volume of the analyte solution.
3. Find the mean (average) molarity of the EDTA titrant by summing the molarities calculated in step 2 and dividing by the total number of trials.
4. Calculate the deviation for each trial by subtracting the mean molarity from the molarity of each trial.
5. Square each deviation calculated in step 4.
6. Sum the squared deviations and divide by the total number of trials minus one (n-1) to find the variance.
7. Calculate the standard deviation by taking the square root of the variance.
8. Calculate the per cent relative standard deviation by dividing the standard deviation by the mean molarity and multiplying by 100.
After following these steps, you will have found the standard deviation and per cent relative standard deviation, which represents the uncertainty in the molarity of your EDTA titrant.

132 gm of CO₂ is generated by combustion of 342 gm of C₈H₁₈.

The molar mass of a chemical compound is defined as the ratio between the mass and the amount of that substance in any sample. A material's molar mass is a bulk characteristic rather than a molecular one.

The molar mass of a substance is its mass expressed in grams per mole. G/mol, or grams per mole, is the sign for molar mass. The ratio between the mass of an isotope and the mass of the isotope carbon is known as the isotopic atomic mass, or mass of a single isotope of any particular element. -12

The reaction is :

C₈H₁₈ + 12.5O₂ ----> 8CO₂ + 9H₂O

Molar mass of C₈H₁₈ is = 12*8 + 18*1 = 114 gm

Molar mass of CO₂ is = 12+ 16*2 = 44gm

The amount of CO that would be required to generate 635 g of CO2 will be 404.14 g

First, let us get the equation of the reaction:

\(2CO + O_2 -- > 2CO_2\)

From the equation, we can see that the mole ratio of CO to that of CO2 is 1:1.

635 g of CO2 is to be generated.

Mole of 635 g CO2 = mass/molar mass = 635/44.01 = 14.43 moles

Thus, the equivalent mole of CO required will also be 14.43 moles.

Mass of 14.43 moles CO = moles x molar mass = 14.43 x 28.01 = 404.14 g

Hence, 404.14 g of CO will be required to produce 635 g of CO2

1 / 102.0 g/mol is the correct way to write the inverted molar mass of aluminum oxide as a conversion factor.

The mass of a specific chemical ingredient or chemical agent (g) multiplied by the quantity of stuff is known as the molar mass (mol). By multiplying the standard atomic weights (in g/mol) of component atoms, one can identify the molar density of a compound. The molar mass of a solid is a bulk attribute rather than a molecular one.

Aluminum oxide has a molar mass of 102.0 g/mol.

1 mol Al₂O₃ = 102.0 g

=> 1 = 1 mol Al₂O₃  / 102.0 g = 1 / 102.0 g/mol

As a result, the conversion factor that you can use to convert aluminum oxide's mass in grams to moles is 1 / 102.0 g/mol.
