Explanation:

Answer: d) The volume occupied by the molecules themselves is no longer negligible. This most be the answer because a, b and c don't make any sense at all.

Explanation:

The volume occupied by the molecules themselves is no longer negligible. Hence, option D is correct.

The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).

The ideal gas law fails at low temperature and high pressure because the volume occupied by the gas is quite small, so the inter-molecular distance between the molecules decreases.

Hence, the volume occupied by the molecules themselves is no longer negligible.

ITS TRUE!!!!!

Answer:

A. 1147.44 grams

Explanation:

Multiply volume by molarity to get the moles of solution.

5.85 M = mol/2.0 L

mol = (5.85 M)(2.0 L)

mol = 11.7

There is 11.7 moles of H2SO4.

Convert to grams with molar mass.

11.7 mol H2SO4 x (98.076 g/1 mol) = 1147.49 g

Closest answer is A, 1147.44 g.

Answer:

Option B

Explanation:

The atmospheric pressure in West Chester, Pennsylvania is lower than the pressure on any summer day in Breckenridge, Colorado

Colorado is 1.6 kilometers above sea level while Pennsylvania is 0.33 kilometers above sea level.

The higher a place is above sea level, the higher is the air pressure.

Hence, option B is correct

Answer:

The heat of vaporization of the gold sample is 1577.397 joules per gram.

Explanation:

The latent heat of vaporization of gold ([tex]h_{v}[/tex]), in kilojoules per gram, is the heat required by a unit mass of gold to transform the material from liquid to gas:

[tex]h_{v} = \frac{E}{m}[/tex] (1)

Where:

[tex]E[/tex] - Energy required for vaporization, in joules.

[tex]m[/tex] - Mass, in grams.

If we know that [tex]E = 92120\,J[/tex] and [tex]m = 58.40\,g[/tex], then the heat of vaporization of the gold sample is:

[tex]h_{v} = \frac{E}{m}[/tex]

[tex]h_{v} = 1577.397\,\frac{J}{g}[/tex]

The heat of vaporization of the gold sample is 1577.397 joules per gram.

Explanation:

The experiment of Ernest Rutherford involved the bombardment of a thin gold foil with alpha particles from a radioactive source. A zinc sulphide screen was used to follow the movement of the alpha particles.

It was discovered that most of the alpha particles  followed a  straight path through the gold foil. Some of them were scattered through large angles and few were even scattered in the backward direction.

Since alpha particles were heavier than electrons, they must have been deflected by very strong forces.

These experimental evidences led to the conclusions stated in the question.

Answer:

Cell division is the process by which a cell, called the parent cell, divides into two cells, called daughter cells.[1] When the cell divides, everything inside it divides also. The nucleus and the chromosomes divide, and the mitochondria divide also.

In mitosis, an ordinary body (somatic) cell divides to make two daughter cells.

In meiosis, a cell divides twice, to produce four gametes (sex cells). The first division of meiosis is a special kind of cell division called a reduction division because the number of chromosomes is halved. The second division of meiosis is similar to mitosis.[2]

Three types of cell division: left is binary fission as in bacteria; right are mitosis and meiosis as in eukaryotes.

Cells are the 'building blocks' of life, and cell division is a basic feature of life. For simple unicellular organisms like Amoebozoa, one cell division reproduces the entire organism. On a larger scale, cell division can create offspring from multicellular organisms, such as plants that grow from cuttings. But most importantly, cell division enables organisms that are able to sexually reproduce to develop from the one-celled fertilised egg (zygote). Cell division also allows for continual renewal and repair of the organism.

The cell division is completed in the four phases prophase, metaphase, anaphase, and telophase.

It is the process by which cells divide into daughter cells. This keeps the cell organism to survive.

The five facts about cell division are:

Therefore, the cell division is completed in the four phases prophase, metaphase, anaphase, and telophase.

Answer:

are u out of time ?

Explanation:

We want to take inventory of the right and left side

Right: S=1 O = 2 Li = 2 Se= 1

Left: S= 1 Se=2 Li= 2 O=1

Lets balance out each side because we see we are off by 1 oxygen on the left

Add a coefficient of 2 on the Li2O

Add a coefficient of 2 on the right Li2Se

Now we have So2+ 2Li2Se ---> SSe2+ 2Li2O

or

The equation is already balanced, assuming that there is supposed to be a yields symbol between 2Li2Se and SSe2.

To find out whether or not this equation is balanced, make a little T-chart with the left side of the equation on one side and the left on the other. Next to each element, write down the amount they start off with and make changes as you add coefficients.

Answer:

81.5g/mol

Explanation:

Molar mass is the ratio between mass of a substance (In this case, 0.207g) and moles presents in this mass.

To solve this question we must find the moles of the gas in order to obtain the molar mass using:

PV = nRT

PV / RT = n

Where P is pressure = 0.980atm

V is volume in Liters = 0.0725L

R is gas constant = 0.082atmL/molK

T is absolute temperature = 68°C + 273.15 = 341.15K

0.980atm*0.0725L / 0.082atmL/molK*341.15K = n

2.54x10⁻³ moles = n

Thus, the molar mass of the gas is:

0.207g / 2.54x10⁻³ moles

Option 2 and 4 are correct

Explanation:

The reactants in the attached image have more enthalpy and hence less stability as they are more reactive. Thus, Product is more stable than the reactants.

This is an addition reaction in which two reactants add up to form the product.

Very less activation energy is required as the reactants themselves are unstable, possess high energy and hence are very reactive.

Reactants have more energy than the products.

Answer:

Solid – In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. Their vibration is related to their kinetic energy. In the solid the particles vibrate in place. The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart.
