A pure substance is indeed a single kind of matter with a uniform and definite composition. In contrast, a mixture is made up of two or more substances that are together in the same place, but each substance maintains its own properties.

Mixtures can be classified as either homogeneous or heterogeneous. A homogeneous mixture has a uniform composition throughout, meaning its components are evenly distributed and not easily distinguishable. Examples include solutions, such as saltwater or air.

On the other hand, a heterogeneous mixture has an uneven distribution of its components, and its individual substances can be easily identified. Examples include sand and water, or oil and water.

One key distinction between a pure substance and a mixture is that a pure substance has a fixed composition, while the composition of a mixture can vary. This means that mixtures can be separated into their individual components through physical processes like filtration, evaporation, or distillation, without undergoing any chemical changes.

In summary, a pure substance is a single type of matter with a definite and uniform composition, while a mixture consists of two or more substances that are combined in the same place, but each substance retains its individual properties. Mixtures can be homogeneous or heterogeneous and can be separated into their components through physical methods.

"   1000 mL "  
       1 L    
___________________  

Explanation:
Note the exact values:  1 L = 1000 mL

                           and:  1000 mL = 1 L .

{Note:  " L = liter(s) " ;  and:  " mL = millileter(s) ".}.

35 L * 1000 mL  
            1 L           ;

We cancel out the 2 (two):  " L " ["Liters"] ; since:  [" L ÷ L = 1 "].

Then we can convert the value—into units of "mL" ;

 →  35 * (1000 mL) = (35 * 1000) mL =  35,000 mL.

We are presented with a reaction that takes place in the gas phase, both reactants and products are in the form of gas. We will apply the ideal gas law to solve the problem. We have the following equation:

where,

P=Pressure=300kPa = 2.96077atm

V of HCN=116 L

T= 1200°C =1473.15K

R= Ideal gas constant = 0.08206 (amt L)/(mol K)

n= Number of moles of HCN

We can find the number of moles of HCN using the ideal gas law. We clear n from the equation:

With this information, we can find the moles of water vapor formed. If we look at the reaction, for every 2 moles of HCN formed, 6 moles of water are formed, the ratio is 1 to 3. So, we must multiply the number of moles of HCN by 3.

Number of moles of water = Number of moles of HCN x 3= 2.84 x 3= 8.52 mol of H2O.

Now we will apply the ideal gas equation again but now we will clear the volume. We will assume that the temperature and pressure remain constant. We have:

So, the volume of water vapour produced is 348L

A pure substance is a form of matter that has a constant composition and properties that are constant throughout the sample. Mixtures are physical combinations of two or more elements and/or compounds.

The final value for the enthalpy change of the formation of CO2 and 2H2O from their elements (C, H2, and O2) would be -1410 kJ per mole of CO2 and 2 moles of H2O formed.

The enthalpy change (ΔH) for the reaction CO2 + 2H2O → H2CO3 can be calculated by multiplying the stoichiometric coefficients of the balanced equation by the enthalpy values of the corresponding compounds involved in the reaction.

In the given reaction, the enthalpy change is -1410 kJ. However, it's important to note that this enthalpy change corresponds to a specific reaction and may not directly apply to the formation of CO2 and 2H2O from another reaction or process.

If we assume that the reaction is the formation of one mole of CO2 and two moles of H2O, we can say that the enthalpy change for this specific formation reaction is -1410 kJ.

Therefore, the final value for the enthalpy change of the formation of CO2 and 2H2O from their elements (C, H2, and O2) would be -1410 kJ per mole of CO2 and 2 moles of H2O formed.

It's worth mentioning that the enthalpy change can vary depending on the specific conditions (temperature, pressure, etc.) and the reactants involved in the reaction. Therefore, it's crucial to specify the conditions and reaction context when referring to enthalpy values.

b. The gas obtained at the anode during the electrolysis of water is oxygen (O2).

c. The volume of gas obtained at the anode is 0.002232 moles or approximately 0.05 L of oxygen gas.

a. The chemical equation for the electrolysis of water is:

2H2O(l) → 2H2(g) + O2(g)

b. The gas obtained at the anode during the electrolysis of water is oxygen (O2).

c. According to the balanced chemical equation, for every 2 moles of water (H2O) electrolyzed, 1 mole of oxygen gas (O2) is obtained. Since 1 mole of any gas occupies 22.4 L at standard temperature and pressure (STP), we can use the stoichiometry of the reaction to determine the volume of oxygen gas produced.

Given that 50 cm³ of gas is obtained at the anode, we need to convert this volume to liters:

50 cm³ = 50/1000 L = 0.05 L

Using the stoichiometric ratio of the balanced equation, we find that 2 moles of water produce 1 mole of oxygen gas. Therefore, 0.05 L of oxygen gas is equivalent to:

0.05 L × (1 mole/22.4 L) = 0.002232 moles

Thus, the volume of gas obtained at the anode is 0.002232 moles or approximately 0.05 L of oxygen gas.

There are 0.2107 moles of KBr are dissolved in 60.2 mL of a 3.50 M solution.

The molarity of a substance is defined as the number of moles of solute present in 1 litre of a solution.

According to the given data, the molarity of the solution tells us that there are 3.50 moles of KBr in 1000mL of solution. But we only have 60.2mL of solution, so with a mathematical rule of three we can calculate the amount of moles in 60.2mL:

1000 ml - 3.50 moles

60.2 ml -x = 60.2 ml× 3.50 moles/1000 ml

x= 60.2 ml -0.2107 moles

0.361 moles of N₂ were required to produce 12.3 g of NH₃, using the balanced chemical equation N₂ + 3H₂ → 2NH₃.

The balanced chemical equation for the reaction is N₂ + 3H₂ → 2NH₃. We can use the balanced equation and the molar mass of NH₃ to calculate the number of moles of N₂ required to produce 12.3 g of NH₃,

1 mol NH₃ = 2 mol N₂ (from the balanced equation)

molar mass of NH₃ = 17.03 g/mol

moles of NH₃ = 12.3 g / 17.03 g/mol

moles of NH₃ = 0.722 mol

moles of N₂ = (0.722 mol NH₃) / 2

moles of N₂ = 0.361 mol

Therefore, 0.361 moles of N₂ were needed to produce 12.3 grams of NH₃.

For each color of paper, the part of white light that is reflected depends on the color of the paper. When white light strikes an object, some of the light is absorbed by the object, some of it is transmitted through the object, and some of it is reflected.

The color of the object that we see is the color of the light that is reflected by the object.

For example, when white light strikes blue paper, the blue color of the paper absorbs all the other colors of the spectrum except blue, which is reflected back to our eyes. This is why we see the paper as blue. Similarly, when white light strikes red paper, the red color of the paper absorbs all the other colors except red, which is reflected back to our eyes. This is why we see the paper as red.

In summary, the color of an object is determined by the color of the light that is reflected by the object, and the color of the light that is reflected depends on the color of the object and the colors of the spectrum that are absorbed or transmitted by the object.
