Particle theory states that particles are attracted to each other??

True or false

Answers

Answer:

true

Explanation:

Students often have no experience with the idea that some things (particles) can’t be divided. If sand is ground up into tiny pieces it is still sand. There seems no reason why the dividing can’t keep on going to smaller and smaller pieces. This is often described as a continuous view of matter.

Even when children are introduced to the idea of matter being made of particles, most consider there is still ‘stuff’ between the particles and that something like air fills the empty space. After all, when liquid is poured from a glass so that it is empty it still contains air.

These ideas are further explored in ‘Hannah’s Question,’ a classroom practice vignette.

Research: Loughran, Berry, Mulhall & Gunstone (2001), Novick & Nussbaum (1981)

Particles are often assumed to behave in the same way as the substances they make up. For example students can believe that particles themselves can swell, shrink and melt or that the particles in stone are harder than the particles in rubber. Many students consider that ice molecules melt to little droplets of water.

Scientific view

The properties of matter can best be explained using a model in which all materials are composed of tiny particles (atoms, molecules and ions).

There is empty space between particles and particles are constantly moving (their speed is changed by temperature). The particles in solids and liquids are quite close to each other, while those in gases are a very long way apart. (There is commonly an increase in volume of at least 1000 fold when substances move from solid or liquid to gas).

Changes of state involving solids, liquids and gases as well as a range of other phenomena can be explained by changes in arrangement and speed of the particles.

Suppose you heat 4.24 g of S8 with 5.00 of Cl2, what would be the theoretical yield of S2Cl2? If the actual yield of S2Cl2 is 6.55g, what is the percent yield

S8 (l) + 4Cl2 (g) ------> 4S2Cl2 (l)

Explanation:

Part 1: Theoretical yield

5.00 + 4.24 = 9.24 grams

Answers

The percent yield of oxygen if 10.2 g of O₂ is produced from the decomposition of 17.0 g of H₂O is 67.6%.

How do we calculate moles from mass?

Moles (n) of any substance can be calculated by using their mass as:

n = W/M, where

W = given mass

M = molar mass

Given chemical reaction is:

2H₂O → 2H₂ + O₂

Moles of 17g H₂O = 17g / 18.02 g/mol = 0.943 moles

From the stoichiometry of the reaction it is clear that,

2 moles of H₂O = produces 1 mole of O₂

0.943 moles of H₂O = produces 1/2×0.943=0.471 mole of O₂

Now mass of this 0.471 moles of O₂ = (0.472mol)(32g/mol) = 15.104 grams

Actual mass of oxygen = 10.2g (given)

Now on putting vales on the percent yield formula, we get

% yield = (10.2 / 15.104)×100% = 67.53% = 67.6%

Hence the required value of percent yield is 67.6%.

Considering the Avogadro's Law, 1.52 moles are left in the container.

Avogadro's Law

Avogadro's Law is a gas law that establishes the relationship between the amount of gas and its volume when temperature and pressure are held constant.

This law states that the volume is directly proportional to the amount of gas: if the amount of gas increases, the volume will increase; while if the amount of gas decreases, the volume decreases.

Mathematically the law can be expressed as:

[tex]\frac{V}{n}=k[/tex]

Assuming that you have a certain amount of gas n1 that occupies a volume V1 and the amount of gas varies until a new value n2, then the volume will change to V2, and the following will be true:

[tex]\frac{V1}{n1}=\frac{V2}{n2}[/tex]

Amount of moles left in this case

In this case, you know:

V1= 65 Ln1= 2 molesV2= 49.4 Ln2= ?

Replacing in the Avogadro's Law:

[tex]\frac{65 L}{2 moles}=\frac{49.4 L}{n2}[/tex]

Solving:

[tex]n2x\frac{65 L}{2 moles}=49.4 L[/tex]

[tex]n2=\frac{49.4 L}{\frac{65 L}{2 moles}}[/tex]

n2= 1.52 moles

Finally, 1.52 moles are left in the container.

Henry's law

This states that the solubility of a gas in liquids at constant temperature is proportional to its pressure. Mathematically, it can be expressed as

S₁ / P₁ = S₂ / P₂

How many carbon atoms does one molecule of pyruvate contain?.

Answers

Hi!one molecule of pyruvate contains three carbon atoms.

Glycolysis produces two pyruvate molecule and there are three carbon atoms are present in each pyruvate molecule.

What is glycolysis ?

Glycolysis is the process in which glucose is broken down to produce energy. It produces two molecules of pyruvate, ATP, NADH and water. The process takes place in the cytoplasm of a cell and does not require oxygen. It occurs in both aerobic and anaerobic organisms.

There are two pyruvate molecules produced at the end of glycolysis for every molecule of glucose metabolized. Therefore, two of the six original carbons will have been eliminated as CO2 at the end of this step.

The main purpose of glycolysis is to provide pyruvate for the trichloroacetic acid (TCA) cycle, not to make adenosine 5′-triphosphate.

Thus, there are three carbon atoms are present in pyruvate compound.

How many moles of nitrogen gas are in 2.00 L of N2 gas at STP

Answers

The number of mole of nitrogen gas in the 16.8 L container is 0.75 mole

Data obtained from the question

Volume (V) = 16.8 L

Pressure (P) = STP = 1 atm

Temperature (T) = STP = 273 K

Gas constant (R) = 0.0821 atm.L/Kmol

Number of mole (n) =?

How to determine the number of mole

The number of mole of the nitrogen gas can be obtained by using the ideal gas equation as illustrated below:

PV = nRT

Divide both side by RT

n = PV / RT

n = (1 × 16.8) / (0.0821 × 273)

n = 0.75 mole
