What would form a negative ion?.

Answers

Answer 1

If an extra electron is pushed into the atom so that it has an excessive number of electrons then it would form a negative ion.

The right side of the Periodic Table, or the side with no metals, is where non-metals are located.

Atoms generally experience atomic radius contraction as a result of adding electrons to the same valence shell and protons to the nucleus, with the smallest atoms to the right of the Periodic Table

As a result, the elements on the right side of the Periodic Table, such as fluorine, chlorine, and oxygen, Tend to be oxidizing, which means that their unshielded nuclear charge causes them to accept electron density.

N³⁻,O²⁻,F⁻ and Cl⁻

Clearly, the Parent atoms (or molecules) are unquestionably oxidizing species.

how many grams of primary standard grade sodium carbonate are necessary to prepare 2.00 l of a 0.0130 m na2co3 solution?

Answers

0.300 g of primary standard grade of sodium carbonate was required

what is primary standard grade ?

A primary standard in chemistry is a reagent that is exceedingly pure, indicative of the amount of moles in the material, and readily weighed. A reagent is a material that is used to initiate a chemical reaction with another substance. Reagents are frequently used to test for the presence or amount of certain compounds in a solution. Primary standards are commonly employed in titration and other analytical chemistry procedures to determine an unknown concentration. Titration is a chemical reaction that happens when modest quantities of a reagent are introduced to a solution. The reaction proves that the solution has a specified concentration. Primary standards are frequently used to create standard solutions, which have a specific concentration.

A good primary standard fulfils the following requirements:

Has a high purity level

It has a modest reactivity.

It has a large comparable weight.

Is unlikely to collect moisture from the air (hygroscopic) in order to decrease mass fluctuations in humid vs dry settings.

Is harmless, cheap, and widely accessible.

Valence electrons important in forming bonds because the formation of the ionic bond and the covalent bond depends on the valence electrons.

The valence electrons are those which are present on the outermost shell of the atom. the valence electron will cause the atoms are unreactive or the highly reactive.

The covalent bond is formed by the sharing of electrons between the atoms. The ionic bonds are formed by the transfer of the electrons between the atoms.

Briefing

2NH₄NO₃ + Na₂CrO₄ → (NH₄)₂CrO₄ + 2NaNO₃

We first convert the given parameters to number of moles

Number of moles = (Mass/Molar mass)

Molar mass of NH₄NO₃ = 80.043 g/mol

Number of moles of NH₄NO₃ = (2.59/80.043) = 0.03224 mole

Number of moles = (Concentration in mol/L) × (Volume in L)

Number of moles of Na₂CrO₄ = 0.4 × 0.2 = 0.08 Mole

2 moles of NH₄NO₃ react with 1 mole of Na₂CrO₄

So, it it evident that NH₄NO₃ is the limiting reagent as it is in short supply in the amount needed for the reaction.

So, the number of moles of ammonium ion in the product is also 0.03224 mole.

The balanced reaction is given as :

C₆H₁₂O₆  +  6H₂O  ---->   12H₂   +   6CO₂

moles of H₂ = 12 mol

mass of glucose = 256 g

moles of glucose = mass / molar

                             = 256 / 180.16

                             = 1.42 mol

Chlorine

Fluorine
−188
Explain the trend in the boiling points of the halogens.

Answers

Answer:

The boiling point of halogens increases down the family.

Explanation:

Boiling Point

Boiling point has multiple factors, but for the purposes of this question, the main factor is IMFs. IMFs are intermolecular forces. IMFs are the attractions that occur between the atoms or molecules of a sample. The stronger the IMFs, the higher the boiling point. This is because strong IMFs hold the molecules together, so it takes more energy to break the attractive forces.

Polarizability

Pure halogens are always non-polar. This means that there are no dipoles or other forms of permanent electron shifts. Since all halogens are nonpolar, there is only one type of IMF: London Dispersion Forces. LDFs are the attractive forces caused by the temporary and random shifts of electron clouds. All molecules experience LDFs. However, LDFs have varying strengths. The larger the molecule, the stronger the LDF. This is due to polarizability. Polarizability is the ease with which electron clouds can shift. Bigger molecules have larger electron clouds, hence the higher polarizability and stronger LDFs.

Since halogens further down the table are larger, both in atomic radius and electron cloud, they have higher polarizability. This leads to stronger LDFs and IMFs. As stated in the first paragraph, strong IMFs cause higher boiling points. This is why larger molecules like Bromine have higher boiling points than small molecules like Fluorine.

Answers

38.52 g of phosphorus-32 was present 9.00 days ago if it has a half-life of 14.3 days

As the half-life of phosphorus-32 is 14.3 days and the remaining amount is given to be 24.9 g and we need to determine the amount present 9 days ago therefore we first determine the number of half-lives that have elapsed as follows;

n = time ÷ half-life

n = 9/14.3

Finally, we can calculate the amount of the radioactive isotope that was available 9 days ago

Amount remaining (N) = 24.9 g

Number of half-lives (n) = 9/14.3

N₀ = 2ⁿ × N

N₀ = 2^(9/14.3) × 24.9

Answers

The concentration terms are molality, normality and mole fraction. Molarity can be used to find out the ionic strength of any solution. Therefore, molarity of diluted solution is 0.27M.

What is molarity?

Molarity can be calculated by dividing number of moles of solute by volume of solution in liter. Molarity is affected by temperature. Its unit is mole/liter. It measure the concentration of any solute in a solution.

Mathematically,

According to the neutralization law,

M₁V₁=M₂V₂

where,

M₁ = molarity of stock solution =1.50M

V₁ = volume of stock solution =  59.0 ml

M₂ = molarity of dilute solution =?

V₂ = volume of dilute solution =228ml

substituting all the given values we get

M₁V₁=M₂V₂

1.50M×59.0 ml=M₂×228

M₂=0.38M

Again diluting this solution

M₂×V₂=M₃×V₃

Though NaBH4 and LiAlH4 are similar, NaBH4 is less reactive. Esters, amides, acids, and nitriles are largely unaffected; its power is limited to reducing aldehydes, ketones, and acid chlorides to alcohols.

Because the hydride ion can attack the planar carbonyl group on either face, the reduction of unsymmetrical ketones with LiAlH4 or NaBH4 results in the production of two stereoisomers: A racemic mixture of enantiomers results from the absence of any additional chiral centers. The intermediates produced by the reaction of sodium borohydride with water are also mild reducing agents known as hydroxyborohydride. The most popular reaction solvents for reduction or organic substrates are ethanol and propane-2-ol, though methanol is also employed.

The new pressure of the container will be 1.14 atm and the most appropriate formula for solving this problem is P/T constant with pressure and temperature as variables.

The most appropriate formula for solving this problem includes the temperature and pressure as variables.

P/T = Constant

Because the volume of the container is constant.

The initial pressure p is 1atm, initial temperature t is 273K and the final temperature T is 311K, the final pressure P will be,

P/T = p/t

Putting values,

P/311 = 1/273

P = 311/273

P = 1.14 atm.

So, the final pressure of the container is 1.14atm.
