Answer:

if by EXACTLY means 130.0000, then the answer is 3.3250

by EXACTLY means 1.299 <Kmass<1.301 then the answer is 3.33

EXPLANATION

which best represents the number of moles in exactly 130 grams of potassium metal?

the elemental mass of K is 39.098

so exactly 130 divided by 39.098 = 3.3250

if by EXACTLY means 130.0000, then the solution is 3.3250 by EXACTLY means 1.299 <Kmass<1.301 is 3.33

Potassium metal responds rapidly with atmospheric oxygen to create flaky white potassium peroxide in exclusively moments of exposure.

It stood preferably isolated from potash, the ashes of plants, from which its appellation derives.

In the systematic table, potassium is one of the alkali metals, all of which have a single valence electron in the outermost electron shell,

That is easily drawn to produce an ion with a positive charge a cation, that connects with anions to form salts. Potassium in disposition materializes only in ionic salts.

When the elementary mass of K is 39.098

Therefore, exactly 130 divided by 39.098 is = 3.3250

Explanation:

To determine the molar mass of any compound, you have to add up the molar masses of every atom that make up the respective compound. In this case NH3 equals one nitrogen atom and three hydrogen atoms.

What does that mean? Ammonia's molar mass will be the sum of the molar mass of one nitrogen atom and 3 times the molar mass of a hydrogen atom.

Answer:

With ions of calcium in a cyclotron. This produced four atoms of moscovium. Moscovium is a synthetic element with the symbol Mc and atomic number 115. It was first synthesized in 2003 by a joint team of Russian and American scientists at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia. In December 2015, it was recognized as one of four new elements by the Joint Working Party of international scientific bodies IUPAC and IUPAP. On 28 November 2016, it was officially named after the Moscow Oblast, in which the JINR is situated.[7][8][9]

Moscovium is an extremely radioactive element: its most stable known isotope, moscovium-290, has a half-life of only 0.65 seconds.[10] In the periodic table, it is a p-block transactinide element. It is a member of the 7th period and is placed in group 15 as the heaviest pnictogen, although it has not been confirmed to behave as a heavier homologue of the pnictogen bismuth. Moscovium is calculated to have some properties similar to its lighter homologues, nitrogen, phosphorus, arsenic, antimony, and bismuth, and to be a post-transition metal, although it should also show several major differences from them. In particular, moscovium should also have significant similarities to thallium, as both have one rather loosely bound electron outside a quasi-closed shell. Over a hundred atoms of moscovium have been observed to date, all of which have been shown to have mass numbers from 286 to 290.

Using calcium ions in a cyclotron. As a result, four moscovium atoms were created. Moscovium is a man-made element with the atomic number 115 and the symbol Mc

Heavy ion collisions in particle accelerators have intentionally produced element 115, also known as Moscovium. So far, about 100 atoms have been seen.

At the Joint Institute for Nuclear Research (JINR) in Dubna, Russia, a team of Russian and American scientists initially created it in 2003.

It was acknowledged as one of four new elements by the Joint Working Party of the worldwide scientific organisations IUPAC and IUPAP in December 2015. It was formally named after the Moscow Oblast on November 28, 2016.

Thus, Element 115 i.e. moscovium was created using calcium ion of cyclotron.

Bond number

The characteristic of reactions that depends on valence electrons is the bond type.

In chemistry, a chemical bond could be;

Ionic

Covalent

The type of bond formed depends on the number of valence electrons present. When there are few valence electrons on an atom, it mostly forms ionic bonds.

When there are more electrons on an atoms, it mostly forms covalent bonds and the electrons between the atoms are shared.

Answer:Butane > ethane > methane, because between bigger molecules there are stronger van der Waals forces and also higher molar mass means they need to be given more energy to have enough kinetic energy to move quickly, freely in gas.

There are multiple butene isomers (Butene) and some (2-Butenes - cis and trans) actually have higher boiling point than n-Butane (there is also Isobutane, of course, with quite much lower boiling point than all of them) and some (1-Butene, Isobutylene) have lower, so this isn't really a fair or simple question. But on simplest level, it can again be said that 1-butene has lower boiling point because it has very similar shape but slightly lower molar mass (2H less) than n-butane.

Explanation:

Intermolecular forces such as dipole-dipole forces, London dispersion forces exist between molecules and these depend on strength of electronegativity of molecule. Therefore, methane converts to gas on boiling due to weak intermolecular forces of attraction between the molecules.

Intermolecular forces of attraction is force of attraction that make two molecule come closer. Intermolecular forces of attraction is directly proportional to the electronegativity of the molecule.

Size of electronegative molecule is small so, if any other molecule or molecule come into contact with this molecule then this molecule attract the electron of other molecule very efficiently and therefore the force between the molecule increases.

Molecules of methane have weak intermolecular forces of attraction. When energy is applied, the methane molecules easily break apart and turn into gas.

Therefore, methane converts to gas on boiling due to weak intermolecular forces of attraction between the molecules.

Imagine A represents a heterogeneous mixture as it is a mixture composition that does not remain the same throughout the mixture whereas Imagine B represents a homogeneous mixture as it does not have any change or irregularity.

A homogeneous mixture is defined as having a fairly uniform form and composition, so many homogeneous mixtures are referred to as solutions whereas heterogeneous mixtures are defined as separate substances or phases. The three states or states of matter are gas, liquid and solid.

Some examples of mixtures that include mixtures of sand and water, mixtures of sugar and salt, and mixtures of lime juice and water.

In homogenous solution, particles are distributed uniformly and have uniform composition while in heterogenous solution, particles are distributed non-uniformly and have non-uniform composition

Thus, Imagine A represents a heterogeneous mixture as it is a mixture composition that does not remain the same throughout the mixture whereas Imagine B represents a homogeneous mixture as it does not have any change or irregularity.

Answer:

The cork cell

Explanation:

This problem is providing information about the volume and concentration of HCl as 505 mL and 0.160 M respectively, and it is asking for the water that have to be added to prepare a 0.100-M solution.

In such a way, we work over the assumption of constant moles in dilution processes, so that we are able to write:

[tex]M_1V_1=M_2V_2[/tex]

Which relates de volume and concentration at the beginning and end of the experiment. This means we can solve for the resulting volume of the solution as a first calculation:

[tex]V_2=\frac{M_1V_1}{M_2}\\\\V_2=\frac{0.160M*505mL}{0.100M}=808mL[/tex]

Hence, the following amount of water must be added:
