Explanation:

Answer:

The nucleus is a collection of particles called protons, which are positively charged, and neutrons, which are electrically neutral. Protons and neutrons are in turn made up of particles called quarks. The chemical element of an atom is determined by the number of protons, or the atomic number, Z, of the nucleus.

Answer:

4C2H5NH2(g) + 15O2(g) →  8CO2(g) + 14H2O(g) + 2N2(g)

Explanation:

The balanced chemical equation  for the given chemical reaction is 4 C₂H₅NH₂(g) + 15 O₂(g) →  8 CO₂(g) + 14 H₂O(g) + 2 N₂(g).

Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.

A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .

The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

The percentage error in the experimental determination is 124%.

The experimentally determined value for Ksp = 1.5×10^−10

The accepted value of Ksp = 1.2 × 10^−12

The formula for percentage error is;

% error = absolute value of ( actual value - experimental value)/actual value × 100/1

% error = absolute value of (1.2 × 10^−12 - 1.5×10^−10)/ 1.2 × 10^−12 × 100/1

% error = 124%

The mass of H2O is produced by the combustion of 1.00 mol of CH4 is 36.0 grams.

The term molar mass is defined as the mass of 1 mole of that particular substance and number of grams per mole of a compound.

The balance chemical equation is as follows:

CH4(g) + 202(g) → CO2(g) + 2H2O(e)

The mass of H2O = 36.0 g

Calculating the mass of H2O produced

mass of H2O = 1.00 mol CH4 × (2 mol H2O / 1 mol CH4) × (18.015 g H2O / 1 mol H2O)

mass H2O = 36.0 grams

Thus, The mass of H2O is produced by the combustion of 1.00 mol of CH4 is 36.0 grams.

Answer:

By satisfying the duet rule or the octet rule, ions are more stable.

Explanation:

Ionic bonds are formed through the exchange of valence electrons between atoms, typically a metal and a nonmetal. The loss or gain of valence electrons allows ions to obey the octet rule and become more stable.

The octet rule states that an atom is most stable when there are eight electrons in its valence shell. Atoms with less than eight electrons tend to satisfy the duet rule, having two electrons in their valence shell. By satisfying the duet rule or the octet rule, ions are more stable.

Answer: Meteorology I believe

Explanation:

The concentration of the solution is 0.132 M, the concentration of the diluted solution is  0.026 M.

Given that;

number of moles = concentration × Volume

Concentration = number of moles/volume

But number of moles = mass/molar mass

mass = 8.63 g

Molar mass =  261.35 g/mol

Hence, number of moles = 8.63 g/261.35 g/mol = 0.033 moles

volume =  250.0 mL or 0.25 L

concentration = 0.033 moles/0.25 L = 0.132 M

For the second part of the question;

Using the dilution formula, C1V1 =C2V2

C1 = initial concentration = 0.132 M

V1 = initial volume = 10.0 mL

C2 = Final concentration = ?

V2 = Final volume = 50.00 mL

C2 =  0.132 M × 10.0 mL/ 50.00 mL

C2 = 0.026 M

Answer:

Dissolving a solid in liquid, such as table salt in water, is a physical change because only the state of the matter has changed.

Explanation:

When a spoonful of table salt (sodium chloride, NaCl) dissolves in a bowl of soup, a physical change occurs  because, the chemical composition of the salt (sodium chloride) remains the same; it's just dispersed in the liquid. This change is known as dissolution or dissolving.

Here's what happens;

Physical Mixing: When you add the salt to the soup, the salt crystals mix with the liquid soup. The salt particles spread out and become evenly distributed throughout the soup.

Solute and Solvent: In this process, the salt is the solute, and the soup is the solvent. The solute is the substance being dissolved (salt), and the solvent is the substance that does the dissolving (soup).

Ion Formation: As the salt crystals dissolve, the sodium (Na+) and chloride (Cl-) ions that make up the salt separate from each other. The water molecules in the soup surround and interact with these ions, helping to pull them apart from the crystal structure.

Ionic Interaction: The charged ions from the salt interact with the polar molecules in the soup, particularly the water molecules. This interaction forms a solution, where the salt ions are evenly dispersed throughout the liquid.

Homogeneity: The resulting mixture appears uniform and homogeneous. You can't easily distinguish the salt from the soup, and the taste of the soup becomes salty due to the presence of dissolved salt ions.

CFCs are 1000-15000 times powerful as compared to greenhouse gas such as CO2.

Chlorofluorocarbons are present in less amount or less abundant than carbon dioxide gas in the atmosphere but they are 10,000 times more powerful as a greenhouse gas.

These CFCS gases can remain in the atmosphere for more than 45 to 100 years. CFCS gases greatly damaged the ozone layer by reacting with it that leads to increase in the diseases such as skin cancer so we can conclude that CFCs are more powerful as compared to carbondioxide gas.
