Separating sand and salt by filtration and evaporation, what are the observations in the experiment?

Answers

While Separating sand and salt by filtration and evaporation, the observation is during the filtration the sand gets accumulated in the filter paper while separating it from the salt solution, while in evaporation the salt gets accumulated.

When we tried to separate the individual components from the mixture of the salt and sand the first step is dissolving the mixture in water as the salt gets dissolved so it is easy for us to filter the sand from the solution, it is followed by the method of evaporation, in which the filtered salt solution is boiled until the water gets evaporated and we are left with the salt,  that's how salt and sand are separated from a mixture.

how do i identify a compound

Answers

Various criteria can be used to categorize chemical substances. One such approach is based on the distinct components present.

All other chemicals are categorized as inorganic, and organic compounds are defined as those possessing a carbon atom backbone. Organometallic compounds are organic molecules bound to metal atoms, as their name suggests.

The sorts of bonds that a compound has served as the basis for another classification system for chemical compounds. Ions are present in ionic compounds, which are held together by the attraction interactions between the ions with opposing charges. One of the most well-known ionic compounds is table salt or sodium chloride.

Answers

A system of two atoms, each having only 3 quantum states of energies 0, e and 2s. The system is in contact with a heat reservoir at temperature T.

The quantum state of a particle is defined by the values of its quantum numbers, so what this implies is that no two electrons within the same atom can have the identical set of quantum numbers.

In natural philosophy, a quantum state may be a mathematical entity that gives a probability distribution for the outcomes of every possible measurement on a system. Knowledge of the quantum state along with the foundations for the system's evolution in time exhausts all which will be predicted about the system's behavior.

For example, the spin of an isolated electron can tackle one amongst only two values; there aren't any other quantum states available for the electron and no intermediate values, since spin is quantized . As a physical parameter is varied, quantum fluctuations can drive a natural action into a special phase of matter.

Answers

The relationship between the volume and the mass of the object is shown by option A.

What is density?

Density gives the ratio of the mass to the volume of an object. We know that volume is an intrinsic property. This implies that it does not change with the amount of the substance. It can be used to identify a given substance because it does not change with the mass or the quantity of the substance present.

It is possible to see that the relationship between the volume and the mass of the object. This relationship is based on the density of the object that is under consideration. The first question that we would have to ask is if the volume changes with the mass of the object.

Given the fact that we have established that the ratio of the mass to the volume of a body is always a constant, we can conclude that the mass does not undergo any change with the volume of the object.

When mercury oxide is heated, it decomposes into mercury and oxygen. If 28. 4 g of mercury oxide decomposes, producing 2. 0 g of oxygen, what is the percent by mass of mercury in mercury oxide?.

Answers

The percent by mass of mercury in mercuric oxide is

93 %.

The molecular formula of mercuric oxide is HgO. Mercury is liquid at room temperature and readily combines with oxygen to form mercuric oxide. Mercury is represented by the symbol Hg. The mass percent is defined as the ratio of the mass of the reactant to the mass of the product into 100. When mercuric oxide undergoes decomposition, it gives mercury and oxygen. And this reaction is endothermic.

The balanced equation for the reaction of mercury oxide is,

[tex]2HgO (s)→ 2Hg (l) + O _{2}(g)[/tex]

Mass of mercury oxide = 28.4 g

Mass of the oxygen = 2 g

The percent by mass of mercury in mercury oxide is,

[tex]Mass ℅= \frac{Mass \: of \: Mercury }{Mass \: of \: Mercury \: oxide} \times 100[/tex]

[tex]= \frac{28.4 - 2}{28.4} \times 100[/tex]

N-Pentane has a higher boiling point than the other three elements

||| < || < | < |V

n-Pentane and 2,2-Dimethylpropane are isomers of one another and have the same chemical formula. Only London dispersion forces (LDFs), the smallest intermolecular forces, exist between the two molecules. The connectedness of the carbon skeleton accounts for the variation in their boiling points. While 2,2-dimethylpropane is a branching hydrocarbon, n-pentane is a straight hydrocarbon. Because of the n-linear pentane's shape, which results in greater surface areas between molecules, there are more LDFs between the molecules. N-Pentane has a higher boiling point as a result.

Because they have hydrogen bonds, 1-pentanol and (R)-4-hydroxypentanoic acid have higher boiling points than hydrocarbons. While (R)-4-hydroxypentanoic acid has both an alcohol group and an acid group, which can also hydrogen, 1-pentanol only has a single alcohol group.

In calculation of various expressions, the results can be expressed in a scientific notation which is a way to compress cumbersome figures.

(4.2 x 104 kg) + (7.9 x 10³ kg)

4.2 × 104 = 436.8

7.9 × 10³ = 7900

436.8 + 7900 = 8,336.8

The scientific notation= 8.3 ×10³kg

(5.23 x 106 um) (7.1 x 10-² μm)

5.23 x 106 um = 554.38um

554.38 × 7.1 = 3,936.1

a liquid when poured into a graduated cylinder is found to weigh 10 n when occupying a volume of 450 ml (milliliters). determine its specific weight, density, and specific gravity.

Answers

The liquid poured into the graduated cylinder has a specific weight, density, and specific gravity of 22,222.22 N/m3, 2,265.26 kg/m3, and 2.26526, respectively.

Given: weight = 10 N  and volume = 450 mL or 0.450 L

The specific weight of a substance is defined as its weight per unit volume or density of a substance multiplied to the acceleration of gravity. To obtain a specific weight with units of N/m3, we will be converting the volume from L to m3.

Specific weight = 10 N / 0.450 L = 22.22 N/L

Specific weight = (22.22 N/L) * (1000 L/ 1 m3) = 22,222.22 N/m3

The density can be determined by dividing specific weight by the acceleration of gravity.

Density = Specific Weight / gravity

Density = 22,222.22 N/m3 / 9.81 m/s2

Density = 2,265.26 kg/m3

Specific gravity is a dimensionless quantity of the ratio of the density of a substance to the density of water. The density of water that will be used is 1000 kg/m3.

Specific gravity = Density of substance / Density of water

Answers

The atomic mass of Indium obtained is 60.544 g

For every 1g of Oxygen  4.784 g of Indium Oxide

Atomic mass of oxygen, O2 = 16.00 g

Now,

For Indium Oxide,

Mass of oxygen present = 3*16.00 = 48.00 g

Mass of Indium Oxide = 4.784 g * 48.00 g = 229.632 g

Let atomic mass of Indium

Mass of Indium Oxide = 2*M  + 3* 16.00 g

229.632 g = 2 * M + 48.00 g

2 M = 181.632 g

M = 181.632 g / 2

M = 90.816 g

For InO

Mass of oxygen present = 1* 16.00 g = 16.00 g

Mass of InO = 4.784 g * 16.00 g = 76.544 g

Let the atomic mass of Indium = M

Mass of InO = M * 1 g + 1*16.00 g

76.544 g = M + 16.00 g

M = 60.544 g

When mixed, acids and bases neutralize one another and produce salts, substances with a salty taste and none of the characteristic properties of either acids or bases.

Identify the products in the chemical
equation below. Count the total number of
atoms on the products side of the chemical
equation.
CH3COOH + NaOH → CH3COONa + H₂O

Answers

The given chemical reaction between acetic acid and sodium hydroxide has sodium acetate and water as its products.

The balanced equation of a chemical reaction between acetic acid and sodium hydroxide is:

[tex]CH_3COOH (aq) + NaOH (aq) \rightarrow CH_3COONa (aq) + H_2O (l)[/tex]

This reaction is a neutralization reaction between a weak acid (acetic acid) and a strong base (sodium hydroxide).

In a neutralization reaction, an acid and a base mix chemically to provide salt and water as the final products. [tex]H^+[/tex] ions and [tex]OH^-[/tex] ions combine to generate water during a neutralization process. Because acid and base balance each other out to create a neutral chemical, this reaction is therefore known as a neutralization reaction.

In a balanced equation, the number of atoms of each element remains the same before and after the reaction. Therefore, in this reaction, on the products side, the number of atoms of Carbon (C) is 2, Hydrogen (H) is 5, Oxygen (O) is 3 and Sodium (Na) is 1.
