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.

Explanation:

Answer:

[OH⁻] = 0.0627M

pOH = 1.20

pH = 12.8

[H⁺] = 1.59x10⁻¹³M

Explanation:

To solve this question we must, as first, find the molarity of Al(OH)₃ in the solution -Molar mass Al(OH)₃: 78.00g/mol-:

0.300g * (1mol/ 78.00g) = 3.846x10⁻³ moles

In 184mL = 0.184L:

3.846x10⁻³ moles / 0.184L = 0.0209M Al(OH)₃. Three times this molarity = [OH⁻]:

[OH⁻] = 0.0209M * 3

pOH = -log [OH⁻] =

pH = 14 - pOH

And [H⁺] = 10^-pH

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:

N₂O

Explanation:

Empirical formula is defined as the simplest whole number ratio of atoms presents in a molecule

For a nitrogen oxide that contains 63.66% of nitrogen, the percent of oxygen must be:

100-63.66 = 36.34% Oxygen

This percent is the percent in mass. To solve this question we must convert the mass of each atom to moles in order to find the simplest whole number ratio:

Moles of the atoms:

N = 63.66g * (1mol / 14g) = 4.547 moles N

O = 36.34g * (1mol / 16g) = 2.271 moles O

The ratio N:O is:

4.547 moles N / 2.271 moles O = 2

That means there are 2 atoms of N per atom of O and the empirical formula is:

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.

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

Aluminum Frame - The aluminum frame is used to protect all the parts of the solar panel. It basically works as a shield against damaging items (hail, ice.)

Tempered Glass - The tempered glass keeps pressure inside the solar panel and keeps compressure outside of the solar panel to protect it from breaking.

EVA - EVA is a great alternative for electric radiational heat. It has a small amount of degradability to sunlight which keeps the panel from burning.

Solar Cells - Solar Cells are the part of the solar panel which work to transform the solar energy into electricity and not just use raw sunlight.

Back Sheet - Back sheets keep solar cells and the top and the bottom of the panel together. They make sure nothing inside the panel comes off.

Junction Box - The junction box makes sure all the solar cells inside of the solar panel are kept together so that the machine works as a whole and the back sheet's function does not get destroyed.

Answer:

For A: The molarity is the solution 9.706 M

For B: The molarity of the solution is 10.91 M.

For C: The molarity of the solution is 1.78 M.

Explanation:

Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L.

The formula used to calculate molarity:

[tex]\text{Molarity of solution}=\frac{\text{Number of moles of solute}}{\text{Volume of solution (L)}}[/tex]                 ......(1)

For A:

Number of moles = 3.30 moles

Volume of solution = 0.340 L

Plugging values in equation 1:

[tex]\text{Molarity of solution}=\frac{3.30 mol}{0.340 L}=9.706 mol/L[/tex]

For B:

Number of moles = 6.00 moles

Volume of solution = 550 mL = 0.550 L        (Conversion factor: 1 L = 1000 mL)

Plugging values in equation 1:

[tex]\text{Molarity of solution}=\frac{6.00 mol}{0.550 L}=10.91 mol/L[/tex]

For C:

Number of moles = 0.0160 moles

Volume of solution = 9.00 mL = 0.009 L

Plugging values in equation 1:

[tex]\text{Molarity of solution}=\frac{0.0160 mol}{0.009 L}=1.78 mol/L[/tex]

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.
