Hydrocarbons are compounds that only consist of hydrogens and carbons.

Saturation

For a hydrocarbon to be saturated, it must have the maximum amount of possible hydrogens. This means that a hydrocarbon will only have single bonds. The hydrocarbon described in the question (known as heptane) is saturated. To find the number of hydrogens in a saturated hydrocarbon we can use the formula 2x+2, where x is the number of carbons.

Thus, the hydrocarbon has 16 hydrogens.

Lewis Structure

The formula above is based on the Lewis structure of hydrocarbons. The Lewis structure of a compound is a visual representation of the elements and bonds within the compound. Another way to find the number of hydrogens is by drawing the complete Lewis structure and then counting the hydrogens. Attached below is the Lewis structure of heptane.

Answer:

a) 6.3 cm

b) 8.0 cm

c) 0.7875

Explanation:

(a) The compound has moved above upto 7.3 cm from the bottom of the paper. Let us assume that line is drawn at 1.0 cm mark as the origin of spot. \

Distance traversed by compound= 7.3 - 1.0 cm = 6.3 cm

(b) Distance traversed by the solvent = 9.0 - 1.0 cm = 8.0 cm

(c) The Rf = Compound Migration distance / Solvent front migration distance

                      = 6.3/8.0 = 0.7875

Taking into account the definition of pH and pOH, the concentration of hydrogen ions and hydroxide ions is 7.94×10⁻¹³ M and 0.0126 M respectively.

pH is a measure of acidity or alkalinity that indicates the amount of hydrogen ions present in a solution or substance.

The pH is defined as the negative base 10 logarithm of the activity of hydrogen ions, that is, the concentration of hydrogen ions or H₃O⁺:

pH= - log [H⁺]= - log [H₃O⁺]

Similarly, pOH is a measure of hydroxyl ions in a solution and is expressed as the logarithm of the concentration of OH⁻ ions, with the sign changed:

pOH= - log [OH⁻]

The following relationship can be established between pH and pOH:

pOH + pH= 14

Being pH= 12.1, the [H₃O⁺] is calculated as:

12.1= - log [H₃O⁺]

Solving:

[H₃O⁺]= 10⁻¹² ¹

[H₃O⁺]= 7.94×10⁻¹³ M

The concentration [H₃O⁺] is 7.94×10⁻¹³ M

Being pH= 12.1, pOH is calculated as:

pOH + 12.1= 14

pOH= 14 - 12.1

pOH= 1.9

Replacing in the definition of pOH the concentration of OH⁻ ions is obtained:

- log [OH⁻]= 1.9

Solving

[OH⁻]= 10⁻¹ ⁹

[OH⁻]= 0.0126 M

In summary, the [OH⁻] is 0.0126 M.

The formula of the hydrate is NiCl2·4.27H2O. The name of the hydrate is nickel (II) chloride tetrahydrate.

To determine the formula and name of the hydrate, we need to first find the value of "x" in the formula NiCl2·xH2O using the given information.

Mass of water = Initial mass - Mass of anhydrous salt

Mass of water = 0.470 g - 0.256 g

Mass of water = 0.214 g

The molar mass of H2O is 18.015 g/mol, so the number of moles of water present in the hydrated salt can be calculated as:

Moles of water = Mass of water / Molar mass of water

Moles of water = 0.214 g / 18.015 g/mol

Moles of water = 0.0119 mol

The number of moles of anhydrous salt can be calculated by dividing its mass by its molar mass:

Moles of anhydrous salt = Mass of anhydrous salt / Molar mass of anhydrous salt

Moles of anhydrous salt = 0.256 g / (Ni: 58.69 g/mol + 2Cl: 2 x 35.45 g/mol)

Moles of anhydrous salt = 0.00279 mol

The ratio of moles of water to moles of anhydrous salt is equal to "x" in the formula NiCl2·xH2O:

Moles of water / Moles of anhydrous salt = x

0.0119 mol / 0.00279 mol = x

x ≈ 4.27

Therefore, the formula of the hydrate is NiCl2·4.27H2O. The name of the hydrate is nickel (II) chloride tetrahydrate.

The best description of the relationship between population size, carrying capacity, and limiting factors is: "The size of a population usually stays near its carrying capacity due to limiting factors."

Carrying capacity refers to the maximum number of individuals that a particular environment can sustainably support. It represents the limit to which a population can grow given the available resources, such as food, water, and habitat. Limiting factors, on the other hand, are the factors that restrict population growth by reducing birth rates, increasing death rates, or limiting access to resources.As a population approaches its carrying capacity, limiting factors come into play and regulate the population size. These limiting factors can include competition for resources, predation, disease, availability of suitable habitat, and other environmental factors. They act as checks on population growth, preventing it from exceeding the carrying capacity of the ecosystem.

Therefore, the size of a population usually stays near its carrying capacity because the limiting factors ensure that the population does not exceed the available resources and ecological limits of the environment. If the population surpasses the carrying capacity, the limiting factors will intensify, causing a decline in resources and an increase in mortality rates, which ultimately brings the population back towards the carrying capacity.It's important to note that the relationship between population size, carrying capacity, and limiting factors is dynamic and can vary depending on various ecological and environmental factors.

The mass of the asteroid is C. 1.2 x \(10^{12}\) Kg

To find the mass of the other asteroid, we can rearrange the equation for the gravitational force between two objects:

F = (G * m1 * m2) / \(r^{2}\)

where F is the force of gravity, G is the gravitational constant, m1 and m2 are the masses of the two asteroids, and r is the distance between them.

Given that the distance between the asteroids is 75000 m, the force of gravity between them is 1.14 N, and one asteroid has a mass of 8 x \(10^{7}\) kg, we can substitute these values into the equation and solve for the mass of the other asteroid (m2):

1.14 N = (6.67430 × \(10^{-11}\) N \(m^{2}\)/\(Kg^{2}\) * 8 x \(10^{7}\) kg * \(m2\)) / \((75000 m)^{2}\)

By using the ideal gas law and Avogadro's number, we find that there are approximately 6.72 × 10^22 molecules of CO2 in 2.5 L at STP.

To determine the number of molecules of CO2 in 2.5 L at STP (Standard Temperature and Pressure), we can use the ideal gas law and Avogadro's number.

Avogadro's number (N_A) is a fundamental constant representing the number of particles (atoms, molecules, ions) in one mole of substance. Its value is approximately 6.022 × 10^23 particles/mol.

STP conditions are defined as a temperature of 273.15 K (0 °C) and a pressure of 1 atmosphere (1 atm).

First, we need to convert the volume from liters to moles of CO2. To do this, we use the ideal gas law equation:

PV = nRT,

where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin.

Since we have STP conditions, we can substitute the values:

(1 atm) × (2.5 L) = n × (0.0821 L·atm/(mol·K)) × (273.15 K).

Simplifying the equation:

2.5 = n × 22.4149.

Solving for n (the number of moles):

n = 2.5 / 22.4149 ≈ 0.1116 moles.

Next, we can calculate the number of molecules using Avogadro's number:

Number of molecules = n × N_A.

Number of molecules = 0.1116 moles × (6.022 × 10^23 particles/mol).

Number of molecules ≈ 6.72 × 10^22 molecules.

Therefore, there are approximately 6.72 × 10^22 molecules of CO2 in 2.5 L at STP.
