I jus need number 6

Low pressure is one of the defining features of a hurricane. Therefore, the correct option is option C.

Hurricanes are intense tropical storms with spiralling winds, copious amounts of rain, and storm surges. These storms can pose a variety of issues when they hit land because they often occur over warm ocean waters close to the equator. Hurricanes leave a path of destruction in their wake, wrecking everything in their path from homes and infrastructure to creating severe flooding and landslides. The unpredictable nature of hurricanes is among their most worrisome features. Although modern technology and meteorological techniques have given us improved storm tracking and prediction systems, it is still challenging to correctly anticipate a hurricane's exact route and intensity.

Answer:

0.01M = [H⁺]; 1x10⁻¹²M = [OH⁻]; Ratio is: 1x10¹⁰

Explanation:

pH is defined as -log [H⁺]

For a pH of 2 we can solve [H⁺] as follows:

pH = -log [H⁺]

2 = -log [H⁺]

10^-2 = [H⁺]

Using Keq of water:

Keq = 1x10⁻¹⁴ = [H⁺] [OH⁻]

1x10⁻¹⁴ / 0.01M = [OH⁻]

Answer:

An ideal gas is a theoretical concept and a real gas behaves in an ideal manner under conditions which includes a high temperature and a low pressure such that the gas has high kinetic energy, and the intermolecular forces between the molecules are weak

The Ideal Gas Law is P·V = n·R·T

Where;

P = The pressure of the gas

V = The volume of the gas

n = The number of moles of the gas

R = The Universal Gas Constant

T = The temperature of the gas

For a gas cooled to 10 Kelvin and placed under high pressure, the interaction between individual gas molecules increases, and the kinetic energy of the gases is much lower and more comparable to the inter molecular forces between the gas molecules, which in turn produces observable changes from the initial ideal behavior of the gas such that the gas behavior deviates from the Ideal Gas Laws appreciably and are better modelled by the Van der Waals Equations which takes into account, the volume the gas particles occupy and the intermolecular forces between the molecules

The Van der Waals equation is presented as follows;

[tex]P = \dfrac{R \cdot T}{V - b} - \dfrac{a}{V^2}[/tex]

Where;

V = The molar volume

a = The gas constant a represents the attractive forces between the gas particles

b = Represent the volume occupied by the particles of the gas

Explanation:

Answer: A, B, & C

Explanation:

A. The ideal gas model assumes that gas particles experience no intermolecular attractions and these forces cause the gas to deviate from ideal behavior.

B. At very low temperatures, gas particles move slowly.

C. At very high pressures, gas particles are very close together.

Answer:

C. Equations that separate the oxidation and reduction parts of the reaction.

Explanation:

Redox half-reactions are actually used when balancing redox reactions. It gives the oxidation or reduction reaction components/parts of a redox reaction.  The change in oxidation and reduction states in the substances that are involved in a redox reaction is used to obtain a redox half-reaction.

This redox half-reaction can also be used to explain what takes place in an electrochemical cell; how the anode is undergoing oxidation and how the cathode is undergoing reduction.

Below is an example of a redox half-reaction:

2 Fe³⁺(aq) + 6e⁻ → 2 Fe(s) (Reduction)

3 Mg(s) → 3 Mg²⁺(aq) + 6e⁻ (Oxidation)

Answer:

B. A carbon monoxide molecule(CO)

Explanation:

CO is polar because oxygen is more electronegative than carbon, so it gives oxygen a partial negative charge and carbon and partial positive charge. This causes a net dipole moment. CO2 is linear with no net dipole moment because each C-O bond is equal and opposite to each other, so they equal 0, which makes them non polar.

0.50 mol SiO₂

Math

Pre-Algebra

Order of Operations: BPEMDAS

Chemistry

Atomic Structure

Step 1: Define

30 g SiO₂ (sand)

Step 2: Identify Conversions

Molar Mass of Si - 28.09 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of SiO₂ - 28.09 + 2(16.00) = 60.09 g/mol

Step 3: Convert

Step 4: Check

Follow sig figs and round. We are given 2 sig figs.

0.499251 mol SiO₂ ≈ 0.50 mol SiO₂

Answer:

[tex]\boxed {\boxed {\sf About \ 0.5 \ moles \ of \ SiO_2}}[/tex]

Explanation:

To convert from grams to moles, we must use the molar mass.

1. Molar Mass

Use the Periodic Table to find the masses of the individual elements (silicon and oxygen) in sand.

Examine the formula for sand: SiO₂. There is a subscript of 2 after oxygen, so there must be 2 oxygen atoms. Multiply oxygen's mass by 2 and add silicon's mass to find the molar mass of sand.

2. Calculate Moles

Use the molar mass as ratio.

[tex]\frac{60.083 \ g \ SiO_2}{1 \ mol \ SiO_2}[/tex]

Multiply by the given number of grams (30)

[tex]30 \ g \ SiO_2 * \frac{60.083 \ g \ SiO_2}{1 \ mol \ SiO_2}[/tex]

Flip the fraction so the grams of sand will cancel.

[tex]30 \ g \ SiO_2 *\frac{1 \ mol \ SiO_2}{60.083 \ g \ SiO_2}[/tex]

[tex]30 *\frac{1 \ mol \ SiO_2}{60.083 }[/tex]

[tex]\frac{30 \ mol \ SiO_2}{60.083 }[/tex]

[tex]0.499309289 \ mol \ SiO_2[/tex]

3. Round

The original measurement of grams has 1 signfiicant figure. We must round our answer to 1 sig fig.

For the answer we found, that is the tenth place. The 9 in the hundredth tells us to round the 4 to a 5.

[tex]\approx 0.5 \ mol \ SiO_2[/tex]

There are about 0.5 moles of SiO₂ in 30 grams.

A dynamic equilibrium exists when chemical reactions or physical movements occur at rates that balance out, creating no net change in a system.

Explanation:

Answer:

The energy transported by a wave is directly proportional to the square of the amplitude. So whatever change occurs in the amplitude, the square of that effect impacts the energy. This means that a doubling of the amplitude results in a quadrupling of the energy.

I think the answer is 3. Highest energy level first, so it fills in the inside rings first

Electrons occupy the lower-energy orbitals first, then go on to fill the next higher-energy orbital until all of the electrons contain been placed.

Most of the time, electrons occupy the lower-energy orbitals first, then go on to fill the next higher-energy orbital until all of the electrons have been positioned.

The lowest energy level is always added to initially until it has as many electrons as it can have. The following higher energy level is then filled with electrons, and so on.

The lowest energy level is always filled up with additional electrons first, up to the point where that level can hold no more, and then further electrons are added to the next higher energy level, and so on. A level's total number of orbitals determines how many electrons can be present at that energy.

Therefore, the correct answer is option 3. Highest energy level first, so it fills in the inside rings first.

Explanation:

Before the advent of the wave-particle duality theory proposed by Louis de Broglie, there was a sharp distinction between mater and waves.

However, Louis de Broglie introduced the idea that mater could display wave-like properties.  Erwin Schrödinger developed this idea into what is now known as the wave mechanical model of the atom.

In this model, electrons are regarded as waves. We can only determine the probability of finding the electron within certain high probability regions within the atom called orbitals.

This idea has been the longest surviving atomic model and has greatly increased our understanding of atoms.
