Explanation:

The bond between magnesium atoms is a metallic bond while the bond within a crystal of aluminum iodide is an ionic bond.

A metallic crystal consists of a sea of electrons that are electrostatically attracted to positive metal ions. This is the nature of the bonding between magnesium atoms in a crystal of magnesium.

In aluminum iodide, there is a transfer of electrons from aluminium to iodine which is typical of an ionic bond. Electrostatic interaction holds oppositely charged ions together in the crystal of aluminum iodide.

Answer: KCIO3

Explanation:

The graph shows that it is the lowest at 0 degrees meaning that it has the lowest solubility

Answer:

KOL c

Explanation:

Answer:

Explanation:

Solid is a hard and not able to flow; not like a liquid or gas. Having no holes; not hollow. Something that is not liquid and gas. Solid has fixed volume but not a fixed shape.

The liquid is something that flows freely; a substance that is not solid or gas.

Gas is a substance that neither liquid nor solid, e.g. air.

Plasma is an electrically neutral ionized gas in an electric discharge; distinctly different from solids and liquids and normal gases.

Therefore, the correct answer is C. solid.

Answer:

A. Liquid

Explanation:

Answer:

Acidic

Explanation:

pH from 0-6.9 are acidic substances

pH of 7 are neutral

pH above 7 to 14 are badic substances

Answer: Acidic

Explanation:

PH of 1-6 is considered acidic.

PH of 7 is neutral.

PH of 8-14 is considered basic (alkaline)

Answer:

5.98 × 10^22 particles

Explanation:

To get the number of particles (nA) in a substance, we multiply the number of moles of the substance by Avogadro's number (6.02 × 10^23)

The mass of Al2(SO4)3 given in this question is as follows: 34grams.

To convert this mass value to moles, we use;

Mole = mass/molar mass

Molar Mass of Al2(SO4)3 = 27(2) + {(32 + 16(4) }3

= 54 + (32 + 64)3

= 54 + 288

= 342g/mol

mole (n) = 34/342

n = 0.0994mol

number of particles (nA) of Al2(SO4)3 = 0.0994 × 6.02 × 10^23

= 0.598 × 10^23

= 5.98 × 10^22 particles

Explanation:

La reacción entre un ácido y una base se llama neutralización. Cuando en la reacción participan un ácido fuerte y una base fuerte se obtiene una sal y agua. Si una de las especies es de naturaleza débil y la neutralización se produce en disolución acuosa también se obtiene su respectiva especie conjugada y agua.

Atomic mass of Sulfur = 32g

32g of Sulfur is one mole.

1g of Sulfur is [tex] \frac{1}{32} moles [/tex]

96.21g of Sulfur is [tex] \frac{96.21}{32} moles=> 3moles(appx) [/tex]

Answer:

[tex]\boxed {\boxed {\sf 3 \ moles \ sulfur}}[/tex]

Explanation:

To convert from grams to moles, the molar mass is used. This value is the number of grams in 1 mole of a substance and it can be found on the Periodic Table. Look for Sulfur or S.

We use this as a ratio.

[tex]\frac {32.07 \ g \ S}{1 \ mo;\l\ S }[/tex]

Multiply by the given number of grams.

[tex]96.21 \ g \ S*\frac {32.07 \ g \ S}{1 \ mo\l\ S }[/tex]

Flip the fraction so the grams of sulfur cancel out.

[tex]96.21 \ g \ S*\frac {1 \ mol \ S}{32.07 \ g \ S }[/tex]

[tex]96.21*\frac {1 \ mol \ S}{32.07 }[/tex]

[tex]\frac {96.21 \ mol \ S}{32.07 }= 3 \ mol \ S[/tex]

96.21 grams of sulfur is equal to 3 moles of sulfur.

Answer:

There would be [tex]20[/tex] neutrons in that atom.

Explanation:

The mass number of an atom is the sum of:

Electrons do not contribute to the mass number of an atom.

From the question:

[tex](\text{Mass Number}) = (\text{Number of protons}) + (\text{Number of neutrons})[/tex].

In this atom:

[tex]39 = 19 + (\text{Number of neutrons})[/tex].

Hence, the number of neutrons would be [tex]39 - 19 = 20[/tex].

Answer:

it decreases

Explanation:

It is a common saying the pressure decreases with height. This means that as altitude increases, the pressure of air decreases. The higher you go above sea level, the pressure becomes lesser.

This is as a result of decrease in the amount of air above sea level and hence a decrease in the density of air as altitude increases.

Hence, with increasing altitude, pressure decreases.

Answer:

It decreases

Explanation:

as pstnonsonjoku says in their answer.

I cannot give you anything more than I just did a question on this an it was correct because i'm in a timed test and just happend to see this!

Have a great nightish day!

Answer:

Element   atom    molar mass     Total        % composition

Na               1            23                    40             57.5 %

O                 1            16                     40              40%

H                1               1                      40              2.5 %

The given compound is NaOH.

Na : number of atom= 1

Molar mass= 23 g/mol

Total mass of NaOH = 40 g/mol

% composition by mass = [tex]\frac{\text {mass of atom}}{\text {Total mass}}\times 100=\frac{23}{40}\times 100=57.5\%[/tex]

O : number of atom= 1

Molar mass= 16 g/mol

Total mass of NaOH = 40 g/mol

% composition by mass = [tex]\frac{\text {mass of atom}}{\text {Total mass}}\times 100=\frac{16}{40}\times 100=40\%[/tex]

H : number of atom= 1

Molar mass= 1 g/mol

Total mass of NaOH = 40 g/mol

% composition by mass = [tex]\frac{\text {mass of atom}}{\text {Total mass}}\times 100=\frac{1}{40}\times 100=2.5\%[/tex]
