The new volume level of the water is 357.84 ml.

The mass of the lead sample = 5 gm

The mass of the iron sample = 3.2 g

The volume of the water = 367 ml

The density of lead = 11.34 g/cc

The density of iron = 7.874 g/cc

[tex]Density = \frac{Mass}{ Volume}[/tex]

[tex] Volume = \frac{ Mass}{Density}[/tex]

The volume of the lead is,

[tex]Volume = \frac{Mass \: of \: lead}{ Density \: of \: lead}[/tex]

[tex] \frac{5}{11.34} [/tex]

= 0.441 ml

The volume of lead is 0.441 ml.

The volume of the iron is,

[tex]Volume = \frac{Mass \: of \: iron}{ Density \: of \: iron}[/tex]

[tex] = \frac{3.2}{7.874} [/tex]

= 0.406 ml

The volume of iron is 0.406 ml.

The new volume level of the water sample is,

New volume = Original water volume + Volume of lead + Volume of iron

= 367 + 0.441 +0.406

= 367.84 ml

The new volume level of the water is 357.84 ml.

Therefore, the new volume level of the water without the unit is 357.84.

The number of covalent bonds formed by carbon is four.

Covalent bonds are formed between carbon atoms and atoms of other elements or carbon. Carbon compounds come in a wide variety, with atom counts ranging from one to thousands.

Since carbon has four valence electrons, it can create four covalent bonds to reach its full outer energy level. The most stable configuration of electrons is at the maximal outer energy level.

Covalent bonds formed between carbon atoms can be single, double, or triple bonds. One pair of electrons is shared by two carbon atoms to form a single bond. They share two pairs of electrons in a double bond and three pairs in a triple bond.

The answer of the resulting Freezing point of the solution is 123.87 g

Molality is a measure of the number of intelligence of solute in a result corresponding to 1 kg or 1000 g of detergent.

This contrast with the description of molarity which grounded on a specified volume of result.

A generally used unit for molality in chemistry is mol / kg.

Now,

Molar mass of an unknown solid = ?

ΔTf = kf * molality for finding molality

Molality = moles / kg solvent

Moles = grams / molar mass

Mass of solute mixed in cyclohexane = 0.4 × 609

Solute mixed in cyclohexane and mixed in cycloheptene= 0.4² × 1000 / 36 π

ΔTf = kf * molality

ΔTf = 2.0920 × 0.4 × 1004 ÷36 × 0.09

M = 9320 / 73.29

M = 123.87 g

Molar mass of unknown solvent = 123.87 g

An 8.638.63 g sample of calcium sulfide was decomposed into its constituent elements and the statement is that every sample of calcium sulfide will have 44.4% mass of sulfur.

According to the law of definite proportions, which is also known as the law of constant composition, pure compound samples always contain the same elements in the same mass proportion.

Stoichiometry in chemistry is also based on this concept and also the law of multiple proportions.

Every sample of a given chemical composition will consist of the same elements in the same combination or ratio.

It is given that,

an 8.638g sample was decomposed into its constituents.

It is producing a total of 4.804g calcium and 3.833g of sulfur.

The mass ratio of Ca: s = 4.804/3.833

=1.253

⇒ mass of calcium = 40.078

mass of sulfur = 32.068

Total mass of CaS = 72.146 grams

mass percentage of Ca = 40.078/72.146 x 100

Using the dilution formula, the dye concentration in the original solution was 0.158 M.

The dye concentration in the original solution is determined from the dilution formula as follows:

Where M₁ = initial concentration

V₁ = original volume

M₂ = final concentration

V₂ = final volume

For the final dilution:

M₁ = M₂V₂/V₁

M₁ = 0.000158 * 100/5

M₁ = 0.000316 M

For the first dilution:

M₁ = M₂V₂/V₁

M₁ = 0.00316 * 100/2

M₁ = 0.158 M

Therefore, the dye concentration in the original solution was 0.158 M.

Water is highly cohesive. Its molecules tend to resist increases in their motion.

When water is heated, some of the energy is used to disturb the hydrogen bonds between neighboring molecules.

Water is abundant. Large bodies of water resist changes in their temperature simply because they are massive objects.

Water is highly cohesive. Its molecules tend to resist increases in their motion.

Due to its extreme density, water can absorb a lot of heat with only a small change in temperature, much like all other dense materials.

Water is very sticky. If water is bonded to another substance, the molecules will tend to "stay put" and resist increases in motion.

Pure water does not resist temperature change.

The hydrogen bonds between water molecules give water the ability to hold heat better than many other substances.

As the temperature rises, the hydrogen bonds between water continually break and reform, allowing for the overall temperature to remain stable, although increased energy is added to the system.

The remaining acetanilide when the solution was cooled to 25°C is 13.513 mg.

What happens in the crystallization process?

The solid compound is dissolved in the solvent at elevated temperatures during the crystallization process, and the crystallized product is obtained by slowly cooling the solution.

Given that,

The solubility of acetanilide at 100°C is 1 g per 10 mL of water. Thus, to dissolve 250 mg of acetanilide at a high temperature, that is 100 °C, we need 2.5 mL of water. At 25°C after the re-crystallization there will be some dissolved acetanilide, which can be calculated as- 185mL of water is needed to dissolve 1g or 1000mg of acetanilide at 25°C. Thus, in 2.5 mL of water, there will be

Metals on reaction with acids liberate Hydrogen gas. This is the reason why bubbles are formed in the solution.

When the metals reacts with acids the mass of the metal will decreases with the liberation of hydrogen gas . This can acts as a exception for law of conservation of mass.

The law of conservation of mass determines  that in a chemical reaction mass can  neither  be created nor destroyed. For instance , the carbon atom in coal as carbon dioxide when it is burned. The carbon atom transforms  from a solid structure to a gas but its mass doesn't  changes.

The principle states  that the mass of matter, in a closed system, will always be the same no matter what type of change  can happens to the matter. Whether it's a change in state, or dissolving, or a chemical reaction, or any combination , the amount of mass will not be   change.

The noble gases family on the periodic table has the highest effective nuclear charge as compared to other groups in the periodic table.

A higher effective nuclear charge leads to greater attractions to the electrons which results in pulling of electron closer to the nucleus which causes in a smaller atomic radius of the atom. When we move down the group, the number of shells or orbits increases, so there is a greater distance between the nucleus and the outermost shell. Effective nuclear charge increases when we move from left to right in the periodic table due to the increasing of atomic charge and shielding effect. Due of a same number of shielding electrons across a period, the valence electrons are pulled more strongly by the protons present in the nucleus. Effective nuclear charge increases when we move from left to right in the periodic table while on the other hand, effective nuclear charge decreases down the group in the periodic table.

So we can conclude that the noble gases family on the periodic table has the highest effective nuclear charge as compared to other groups in the periodic table.
