How would it have been if particles of matter had no space?

The four main components of a modern detergent are builders (50% by weight), surfactants (15%), bleach (7%), and enzymes (2%).

A detergent can be described as a surfactant or a mixture of surfactants with cleansing properties in dilute solutions. These substances are similar to soap but are more soluble in hard water due to the polar sulfonate is less likely than the polar carboxylate of soap to bind ions in hard water.

Builders are water softeners and their anions react with cations to form insoluble compounds which precipitate onto fabrics and washing machines and which are hard to remove.

Surfactants provide absorption and emulsification of soil into the water and also by reducing the surface tension of water to improve wetting.  The main function of bleaches is oxidizable organic stains, which are usually of vegetable origin.

Enzymes are needed to degrade stubborn stains composed of proteins, fats, starch, and cellulose.

Answer:  8855 Joules energy is released when 115 g of \(CHCl_3\) changes from a liquid to a solid at  its freezing point.

Explanation:

Latent heat of freezing is the amount of heat released to convert 1 mole of  liquid to solid at atmospheric pressure.

Amount of heat released to freeze 1 gram of \(CHCl_3\) = 77 J/g

Mass of \(CHCl_3\) given = 115 gram

Heat released when 1 g of \(CHCl_3\) is freezed = 77 J

Thus Heat released when 115 g of \(CHCl_3\) is freezed =\(\frac{77}{1}\times 115=8855J\)

Thus 8855 Joules energy is released when 115 g of \(CHCl_3\) changes from a liquid to a solid at  its freezing point.

Based in the equation of the reaction reaction:

The equation of the reaction is given below:

From the equation of the reaction 2 moles of NH3 reacts with 1 mole of MgSO4

5.4 moles of NH3 will react with 5.4/2 moles of MgSO4 = 2.7 moles of MgSO4.

Therefore, MgSO4 is in excess and NH3 is the limiting reactant.

Since NH3 is the limiting reactant:

2 moles of NH3 will produce 1 moles of Mg(OH)2

5.4 moles of NH3 will produce 5.4÷2 moles of Mg(OH)2 = 2.7 moles of Mg(OH)2

Therefore, the greatest amount of Mg(OH)2 produced is 2.7 moles.

MgSO4 is the excess reactant.

2.7 moles of MgSO4 are needed but there are 4.6 moles present.

Moles left over = 4.6 - 2.7 = 1.9 moles

Therefore, 1.9 moles of the excess reactant are left over.

Amanda’s ball is heavier so it’s harder throw. This was illustrated in the bowling.

Amanda was having such a difficult time because she chose a heavier ball.

Evidence: Jason had no trouble with his 6lb ball, while Amanda struggled with double the weight of Jason's ball, which was 12lb and had more mass.

Reasoning: Jason chose a ball with less mass weighting at 6 pounds, but his ball was more simpler to roll as a result. This was owing to Newton's second law, as having a lighter ball made it easier for him to pass through. Amanda, on the other hand, had a ball that was so heavy that it was difficult to throw.

The equilibrium constant of 1.1x10^8 for the reaction NO(g) + Cl2(g) ⇌ NOCl(g) + Cl(g) at a particular temperature indicates that the forward reaction (formation of NOCl and Cl) is favored at equilibrium.

In a chemical reaction, the equilibrium constant (K) expresses the ratio of the concentrations (or partial pressures) of the products to the concentrations (or partial pressures) of the reactants, each raised to their respective stoichiometric coefficients. A high equilibrium constant, such as 1.1x10^8, indicates a large concentration of products relative to reactants at equilibrium.

In this case, the high value of the equilibrium constant suggests that the forward reaction (NO + Cl2 → NOCl + Cl) is highly favorable and proceeds to a significant extent, while the reverse reaction (NOCl + Cl → NO + Cl2) is less favored.

This implies that the formation of NOCl and Cl is thermodynamically favored, and the system will tend to reach an equilibrium state where the concentrations of NOCl and Cl are relatively higher compared to NO and Cl2.

The specific value of the equilibrium constant indicates the extent to which the reaction proceeds in the forward direction. In this case, the large value of 1.1x10^8 indicates that the forward reaction is highly favored and the equilibrium mixture will contain a significantly higher concentration of NOCl and Cl compared to NO and Cl2.

Approximately 8.79 grams of CO₂ are produced when 20 grams of CaCO₃ and 25 grams of HCl are mixed.

The balanced chemical equation for the reaction between calcium carbonate (CaCO₃) and hydrochloric acid (HCl) is:

CaCO₃ + 2HCl → CaCl₂ + CO₂ + H₂O

From the equation, we can see that 1 mole of CaCO₃ reacts with 2 moles of HCl to produce 1 mole of CO₂. The molar mass of CaCO₃ is 100.09 g/mol, and the molar mass of HCl is 36.46 g/mol.

To find the mass of CO₂ produced, we need to determine which reactant is limiting. This can be done by calculating the number of moles of each reactant and comparing them to the stoichiometric ratio in the balanced equation.

Number of moles of CaCO₃ = 20 g / 100.09 g/mol = 0.1998 mol

Number of moles of HCl = 25 g / 36.46 g/mol = 0.685 mol

According to the balanced equation, 1 mole of CaCO₃ reacts with 2 moles of HCl. Therefore, the limiting reactant is CaCO₃, since only 0.1998 moles of CaCO₃ are available to react with HCl.

From the balanced equation, we know that 1 mole of CaCO₃ produces 1 mole of CO₂. Therefore, the number of moles of CO₂ produced is also 0.1998 mol.

The molar mass of CO₂ is 44.01 g/mol. Therefore, the mass of CO₂ produced is:

Mass of CO= 0.1998 mol x 44.01 g/mol = 8.79 g

Therefore, approximately 8.79 grams of CO₂ are produced when 20 grams of CaCO₃ and 25 grams of HCl are mixed.

The pH of the resulting solution after adding a 10.0 mL portion of 0.010 M HCl to 100.0 mL of water is approximately 2.00.This pH value indicates the high concentration of H+ ions resulting from the complete dissociation of the strong acid, HCl, in water.

To calculate the pH of the resulting solution, we need to consider the dissociation of HCl in water. HCl is a strong acid that completely dissociates into H+ and Cl- ions in aqueous solution.

Given that the initial concentration of HCl is 0.010 M and the volume added is 10.0 mL, we can calculate the moles of HCl added:

Moles of HCl = concentration x volume

            = 0.010 M x 0.0100 L

            = 0.0001 moles

The total volume of the resulting solution is 100.0 mL + 10.0 mL = 110.0 mL = 0.110 L.

Since HCl is a strong acid, it completely dissociates, and the moles of H+ ions formed will be equal to the moles of HCl added.

Therefore, the concentration of H+ ions in the resulting solution is:

Concentration of H+ ions = moles of H+ ions / total volume

                       = 0.0001 moles / 0.110 L

                       = 0.000909 M

To calculate the pH, we use the equation:

pH = -log[H+]

pH = -log(0.000909)

   ≈ 2.00

Therefore, the pH of the resulting solution is approximately 2.00.

After adding a 10.0 mL portion of 0.010 M HCl to 100.0 mL of water, the resulting solution has a pH of approximately 2.00. This pH value indicates the high concentration of H+ ions resulting from the complete dissociation of the strong acid, HCl, in water.

Explanation:

The number of moles of gas contained in the cylinder is approximately 0.381 moles.

To calculate the number of moles of gas contained in the cylinder, we can use the ideal gas law equation:

PV = nRT

Where:

P = Pressure (in atm)

V = Volume (in L)

n = Number of moles

R = Ideal gas constant (0.0821 L·atm/(mol·K))

T = Temperature (in Kelvin)

We need to convert the temperature from Celsius to Kelvin by adding 273.15:

T = 23.8 °C + 273.15 = 296.95 K

Now, we can rearrange the ideal gas law equation to solve for the number of moles (n):

n = PV / RT

Plugging in the values:

P = 4.26 atm

V = 15.0 L

R = 0.0821 L·atm/(mol·K)

T = 296.95 K

n = (4.26 atm)(15.0 L) / (0.0821 L·atm/(mol·K))(296.95 K)

The arrangements of particles at the atomic level for a liquid and a solid are compared as the particles in gas do not follow any specific order and are uniformly spaced out.

There is no regular arrangement of liquids next to one another. The solids are regularly arranged and closely packed. Since liquid particles are more dispersed than solid ones, they take on the shape of their container rather than having a distinct shape yet having a distinct volume. Because solid particles are more closely packed together and certain solids even have atomic-level particle patterns, they have a distinct shape that does not alter unless the solid changes state.

The arrangement of the particles in a liquid is more haphazard than that of the particles in a solid. But since they are closely packed, the atoms of solids and liquids are comparable.
