Answer:

[tex]\boxed {\boxed {\sf 4.60 \times 10^{23} \ atoms \ Mg}}[/tex]

Explanation:

We are asked to find how many atoms of magnesium are in 0.764 moles of magnesium.

We convert moles to atoms using Avogadro's Number or 6.022 × 10²³. This is the number of particles (atoms, molecules, formula units, etc.) in 1 mole of a substance. In this case, the particles are atoms of magnesium. So, there are 6.022 × 10²³ atoms of magnesium in 1 mole of magnesium.

Convert using dimensional analysis and set up a conversion factor using Avogadro's Number.

[tex]\frac{6.022 \times 10^{23} \ atoms \ Mg}{1 \ mol \ Mg}[/tex]

We are converting 0.764 moles of magnesium to atoms, so we multiply by this value.

[tex]0.764 \ mol \ Mg *\frac{6.022 \times 10^{23} \ atoms \ Mg}{1 \ mol \ Mg}[/tex]

The units of moles of magnesium cancel.

[tex]0.764 *\frac{6.022 \times 10^{23} \ atoms \ Mg}{1 }[/tex]

[tex]0.764 *6.022 \times 10^{23} \ atoms \ Mg[/tex]

[tex]4.600808 \times 10^{23} \ atoms \ Mg[/tex]

The original value of moles (0.764) has 3 significant figures, so our answer must have the same. For the number we calculated, that is the hundredth place. The 0 in the thousandth place tells us to leave the 0 in the hundredth place.

[tex]4.60 \times 10^{23} \ atoms \ Mg[/tex]

0.764 moles of magnesium contains approximately 4.60 × 10²³ atoms of magnesium.

Since Ghs. 421.78 was deducted from Adjoa's salary pay, her take home pay is Ghs. 4265.46.

Given the following data:

Gross profit can be defined as the profit earned by a business after subtracting its cost of manufacturing and distributing goods from its total revenue (sales).

On a related note, gross salary is the amount of money earned by an individual before any deduction such as tax.

To find how much take home pay Adjoa earned this past month:

[tex]Take\;home = Gross\;salary - deduction\\\\Take\;home = 4687.24 - 421.78[/tex]

According to the molecular geometry, bonds in carbon tetrachloride are polar and that in nitrogen are non polar.

Molecular geometry can be defined as a three -dimensional arrangement of atoms which constitute the molecule.It includes parameters like bond length,bond angle and torsional angles.

It influences many properties of molecules like reactivity,polarity color,magnetism .The molecular geometry can be determined by various spectroscopic methods and diffraction methods , some of which are infrared,microwave and Raman spectroscopy.

They provide information about geometry by taking into considerations the vibrational and rotational absorbance of a substance.Neutron and electron diffraction techniques provide information about the distance between nuclei and electron density.

Carbon and oxygen atoms in (CH3)2C=O form sigma and pi bonds. The pi bonds are formed using unhybridized p orbitals.

Acetone (CH3)2C=O contains the carbonyl group (C=O). Carbon is bonded to oxygen via a double bond as shown in the orbital structure. The carbon atom is also bonded to two methyl groups.

The central carbon  atom is sp2 hybridized as well as the oxygen atom in acetone. The pi bond is formed by the overlap of unhybridized p orbitals on both carbon and oxygen atoms. The sigma bonds are formed using the sp2 hybridized carbon atoms on carbon and oxygen.

Tin has electron configuration [Kr] 5s²4d¹⁰5p² and it is not a transition element because its outermost orbitals are 5s² 5p². It has oxidation states of +2 and +4.

The electron configuration of tin is [Kr] 5s²4d¹⁰5p². The electronic structure of an atom shows the arrangement of electrons in the atom of an element. The electrons are arranged in sub-shells.

Tin is not a transition metal because it has a completely filled d sub-shell and  its outermost shell consists of ns, np orbitals.

Tin looses its electrons in pairs. Remember that the outermost orbitals are  5s² 5p². This means that tin can have two stable oxidation states, +2 and +4.

I would say baking powder maybe or you should try tap water

Answer:

1st one - tap water (ill go over them one by one to help you understand why)

Its honestly rather vinegar or tap water but if I would go with tap water however I could be wrong. I don't take your class lol

Step by step:

First, tap water includes a lot of ions and contaminants. As a result, tap water only contains ions capable of conducting electricity. As a result, tap water is an excellent electrical conductor.

2nd) Ammonia and baking soda are both weak bases. When weak electrolytes dissolve in water, the resulting solution has a low conductivity.

Third, because it releases H+ and CH3COO- ions, the mobility of these ions in the solution assists in electrical conduction. As a result, vinegar is a good electrical conductor.

4th) When dissolved in water, soda compounds (chemicals mostly containing sodium) include ions, and ions assist conduct electricity. As a result, it does not conduct because it lacks ions or charged particles.

The atomic mass of K is 39

from Avogadro's law

39g of K contains 6.02x10^23 atoms

therefore if

39=6.02x19^23

X=5.11×10^22

making X the subject of the formula

X= (5.11×10^22×39)÷6.02×10^23

X= 33g

The statement, that describes grams of potassium (K) contain 5.11 × [tex]10^{22}[/tex] atoms is "33.1 g."

An atom is a fundamental particle of matter that contains at least one proton.

1 mole will be of 6.022 × [tex]10^{23}[/tex] atoms

Then,

[tex]= 5.11*10^{22} \;atoms\;.\;\frac{1\;mol}{6.022*10^{23} \;atoms} \;.\;39.098\;g/mol\\\\= 33.171\;g[/tex]

≈ 33.1 g

As a result, 33.1 g of K contains 5.11 × [tex]10^{22}[/tex] atoms.

Hence, the correct option is 33.1 g.

Answer:

methanol because it is liquid at room temperature which means that it melts at a lower temperature

Silicon dioxide is a solid at room temperature and methanol is a liquid. Silicon dioxide has a higher melting point than methanol because silicon dioxide is solid, and with increasing temperature, it will melt.

Melting point is that point or temperature at which the solid items are converted into liquid, and it changes their atoms and the atoms lose their compactness.

Here, two compounds are given, Silicon dioxide and methanol, the first one is solid at room temperature, so it will need more temperature to melt down and methanol is still liquid at room temperature, so its melting point is low.

Thus, methanol is a liquid while silicon dioxide is a solid at ambient temperature. Because silicon dioxide is a solid and melts at greater temperatures, it has a higher melting point than methanol.
