His conclusions resulted in the ____________, which helped to explain that ________ in chemical reactions separate, ________ or ___________, but are not created, ___________, or _________.

Answer:

smallest to largest:

Electron, Neutron, Atom, Molecule, Nucleus

Explanation:

sorry if it's not right

Electron--Neutron--Nucleus-- atom--Molecule is the order from smallest to largest.

Electron is the smallest subatomic particles having the radius is about 9.1× 10−31 kg while on the other hand, the size of neutrin is 1.7×10−15 meters. Both neutron and proton are present in the nucleus so nucleus is bigger than neutron. Nucleus is present inside an atom so atom is bigger than nucleus whereas atom is smaller than molecule.

So we can conclude that Electron--Neutron--Nucleus-- atom--Molecule is the order from smallest to largest.

They combine to form water

A neutralisation reaction is a type of chemical reaction whereby an acid and base reacts in an aqueous solution

to form salt and water only.

For example, the acid HCl reacts with the base NaOH to give salt (NaCl) and water (H2O).

Positive sodium ions from NaOH and negative chloride ions from HCL combine to form the salt sodium chloride (NaCl).

While the H+ from the acid and OH− from base combine to form water.

Therefore, when HCl and NaOH react in an aqueous solution the H+ and OH− combine to form water.

Answer:

280 g Al₂O₃

Explanation:

To find the mass, you need to multiply the given value by the molar mass. This will cause the conversion because the molar mass exists as a ratio; technically, the ratio states that there are 101.96 grams per every 1 mole Al₂O₃. It is important to arrange the ratio in a way that allows for the cancellation of units. In this case, the desired unit (grams) should be in the numerator. The final answer should have 2 sig figs to reflect the given value (2.7 mol).

Molar Mass (Al₂O₃): 101.96 g/mol

2.7 moles Al₂O₃          101.96 g

1) The reaction is exothermic and heat is a product

2) The color would turn to pink.

Let us recall that an endothermic reaction is one in which the increase in the temperature of the system would drive the forward reaction. This implies that the equilibrium would shift to the right when the set up is heated. Since the color of the solution changes to blue when heated hence the reaction is exothermic.

If you removed heat by placing the solution in the ice bath, we can see that we have removed the heat thus we expect that the reverse reaction would take place and the color would change to pink.

In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.

There are two different types of genetic inheritance, full dominance and codominance. Codominance basically means that neither allele is able to suppress or obstruct the expression of the other allele. However, incomplete dominance occurs when a dominant allele only partially obscures the effects of a recessive gene.

Codominance occurs when the phenotype displays both alleles present in the genotype. A combination of the alleles in the genotype can be reflected in the phenotype in incomplete dominance.

The third law of thermodynamics describes the entropy of a: solid.

The third law of thermodynamics states that the entropy of a pure crystalline substance approaches zero as the temperature approaches absolute zero (0 Kelvin or -273.15 degrees Celsius). This law implies that at absolute zero, a perfectly ordered and pure crystalline solid will have zero entropy.

The third law of thermodynamics is not specific to liquids or gases but applies to solids. In a solid, the molecules are highly ordered and have fixed positions in a regular lattice structure. As the temperature decreases towards absolute zero, the thermal motion of the molecules reduces, and the system becomes more ordered, resulting in a decrease in entropy.

In contrast, liquids and gases have higher entropy compared to solids at absolute zero because their molecules have more freedom of movement and are not as tightly arranged. Therefore, the third law of thermodynamics specifically addresses the entropy of solids and does not apply to liquids or gases.

1) The speed of the particles would increase when heated

2) The balloon would expand when heated and contract when cooled.

3) On a hot day, the pressure of the gas in a beverage increases

4) The mercury thermometer works by expanding or contracting in response to temperature change.

We know that one of the effects of temperature is that it is able change the molecular motion of an object. Thus the molecules of an object are able to move faster when heat is applied and they are able to slow down when the heat is removed.

This is why a balloon would have a greater volume when the temperature is increased as the gas molecules spread out. The volume would reduce or decrease when the temperature is reduced.

Also, on a hot day, a beverage would tend to be more fuzzy as the pressure of the gas in the beverage would increase as the temperature is increased.

Lastly, when we use the mercury thermometer, the volume of the mercury would increase and this is the reason for the expansion of the mercury during temperature measurement.

The heat of reaction (ΔH) for the given reaction is 180.4 kJ/mol. To calculate the heat of reaction (ΔH) for the given reaction:

CCl₄(g) + H₂O(g) -> CHCl₃(g) + HCl(g)

You would need the standard enthalpies of formation for each compound involved in the reaction. The standard enthalpy of formation (ΔHf) is the enthalpy change when one mole of a compound is formed from its elements in their standard states.

Here are the standard enthalpies of formation for the compounds involved:

ΔHf[CCl₄(g)] = -135.5 kJ/mol

ΔHf[H₂O(g)] = -241.8 kJ/mol

ΔHf[CHCl₃(g)] = -104.7 kJ/mol

ΔHf[HCl(g)] = -92.3 kJ/mol

To calculate ΔH for the reaction, you need to sum up the enthalpies of formation of the products and subtract the sum of the enthalpies of formation of the reactants:

ΔH = ΣΔHf(products) - ΣΔHf(reactants)

ΔH = [ΔHf[CHCl₃(g)] + ΔHf[HCl(g)]] - [ΔHf[CCl₄(g)] + ΔHf[H₂O(g)]]

ΔH = [(-104.7 kJ/mol) + (-92.3 kJ/mol)] - [(-135.5 kJ/mol) + (-241.8 kJ/mol)]

ΔH = -196.9 kJ/mol - (-377.3 kJ/mol)

ΔH = 180.4 kJ/mol

Therefore, the heat of reaction (ΔH) for the given reaction is 180.4 kJ/mol.

The molar concentration of Al(OH)₃ in the solution is 1.61 M.

we need to calculate the number of moles of Al(OH)3 in the solution:

Number of moles of Al(OH)₃ = mass of Al(OH)3 / molar mass of Al(OH)3

Molar mass of Al(OH)₃ = (1 x atomic mass of Al) + (3 x atomic mass of O) + (3 x atomic mass of H)

Molar mass of Al(OH)₃ = (1 x 26.98 g/mol) + (3 x 16.00 g/mol) + (3 x 1.01 g/mol) = 78.00 g/mol

Number of moles of Al(OH)₃ = 62.7 g / 78.00 g/mol = 0.804 moles

Next, we need to calculate the volume of the solution in liters:

Volume of solution = 500.0 mL = 500.0 mL x (1 L/1000 mL) = 0.500 L

Finally, we can calculate the molar concentration of Al(OH)₃

Molarity = moles of solute/volume of solution in liters

Molarity = 0.804 moles / 0.500 L = 1.61 M

Therefore, the molar concentration of Al(OH)₃ in the solution is 1.61 M.
