Explanation: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.
2(7) + 2 = 16Thus, 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.

What is radiant energy?The physical energy produced by electromagnetic radiation is known as radiant energy, and it is typically seen as a source's radiation spreads out into its surroundings. All types of electromagnetic radiation, such as gamma rays, x-rays, radio waves, microwaves, light, and heat, are examples of radiative energy sources. Of However, compared to other sources of radiant energy, human people do produce some radiant energy, albeit a very small amount. Actually, thermal energy—a.k.a. heat—is the form of electromagnetic radiation that all living things produce. Since it mainly belongs to the infrared region of the spectrum, it is invisible to the unaided eye.The energy of electromagnetic waves is known as radiant energy. The emission of energy as electromagnetic waves is known as radiation. A form of radiant energy that can be seen by the human eye is light energy.

According to the Law of Constant Composition, vanadium and oxygen do not mix with the other three elements; their combined masses are 12.74 mg V: 10.00 mg.
What two parts of Dalton's theory were incorrect?It is untrue that an atom is the smallest particle because protons, neutrons, and electrons may be separated from it to form other subatomic particles. Because some elements show various atoms having different masses, an atom of the same element has the same mass, and the form is therefore wrong (isotopes). The law of multiple proportions states that the weights of each element that combine with a set weight of the other to form a compound are in a ratio of small whole numbers.A theory of atoms. Dalton's assertion that atoms are indestructible was refuted in 1897 by English physicist J. J. Thomson (1856–1940).

How many moles of C3H8 (molar mass 44.09 g/mol) are represented by 6.21 g of this compound? Give your answer correctly to three significant digits.
Answers
Answer:
0.141 moles of C₃H₈
Explanation:
The molar mass of C₃H₈ is 44.09 g/mol. To convert the mass of a substance to moles, we use the formula:
moles = mass / molar mass
where mass is the given mass of the substance in grams and molar mass is the molar mass of the substance in g/mol.
So, the number of moles of C₃H₈ represented by 6.21 g of this compound is:
moles = 6.21 g / 44.09 g/mol = 0.1408 moles C₃H₈
Therefore, to three significant digits, 6.21 g of C₃H₈ represent 0.141 moles of the compound.
The number of moles of [tex]C_{3}H_{8}[/tex] represented by 6.21 g of this compound is 0.141 moles. This can be calculated using the provided molar mass and the formula for the number of moles.
Explanation:In the field of chemistry, to calculate the number of moles in a given mass of a compound, we have to use the molar mass of the compound. In this case, the substance is propane \ which has a molar mass of 44.09 g/mol. Therefore, to find the number of moles in 6.21 g of \[tex]C_{3}H_{8}[/tex]8, we use the formula:
Number of moles = Mass of Substance (g) / Molar Mass (g/mol)
Substituting the given values into the equation:
Moles of [tex]C_{3}H_{8}[/tex] = 6.21 g / 44.09 g/mol = 0.141 moles
To three significant digits, the answer is 0.141 moles of [tex]C_{3}H_{8}[/tex]represented by 6.21 g of this compound.

make a claim about how the locations of volcanoes are related to the tectonic plate boundaries. summarize evidence to support the claim and explain your reasoning
Answers
Volcanoes form when tectonic plates move and interact with each other.
What are volcanos?
Volcanoes are openings in the Earth's crust where molten rock, ash, and gas escape to the Earth's surface. They can be found on land, underwater, and on the ocean floor. Volcanoes are caused by the movement of tectonic plates and the release of pressure from the Earth's interior. Volcanic eruptions can cause destruction and endanger human lives, but they also create new land and provide nutrients for the environment.
Claim: Volcanoes are located along tectonic plate boundaries because these boundaries are areas of high geological activity.
Evidence: Geological evidence has shown that most of the world's volcanoes are located along plate boundaries, such as the Ring of Fire in the Pacific Ocean. This is because plate boundaries are areas of high geological activity, with earthquakes, magma upwelling, and other events. Plate boundaries are also home to many of the world's most active volcanoes, such as Mount St. Helens in the United States.
Reasoning: The evidence supports the claim that volcanoes are located along tectonic plate boundaries because these boundaries are areas of high geological activity. The presence of earthquakes and magma upwelling suggests that these areas are more likely to have volcanic eruptions. Plate boundaries are also home to some of the world's most active volcanoes, which further reinforces the claim.

The half life of tritium is 12.3 years. If 48.0 mg of tritium is released from a nuclear power plant during the course of a mishap, what mass will remain after 27 years? Please show work I’m down bad
Answers
Answer:
Explanation:
The half-life of tritium is 12.3 years, which means that after 12.3 years, half of the remaining tritium will decay. To calculate how much of the 48.0mg sample will remain after 27 years, we can use the formula:
A = A0 * (1/2)^(t/T)
Where A is the remaining amount, A0 is the initial amount (48.0mg), t is the time elapsed (27 years), and T is the half-life (12.3 years).
Plugging in the values, we get:
A = 48.0 * (1/2)^(27/12.3)
A = 48.0 * (1/2)^2.18
A = 48.0 * (1/4.77)
A = 10.04 mg
So after 27 years, 10.04mg of the 48.0mg sample will remain.

An object has a volume of 120cm 3rd power and a mass 40. grams. Will the object float or sink?
Answers
Regardless of size, shape, or substance of construction, heavy objects sink while light objects float. A floating object must be entirely above the liquid's surface to qualify as such.
Does mass affect floating and sinking?According to its size, something's density tells us how heavy it is. When placed in water, a dense object will float if it is less dense than the water, and vice versa if it is more dense.
To be more precise, when submerged in water, a weighted object sinks until it moves the same volume of water as it does. Objects drop farther the more mass they possess. Until it moves 1 g of water, a 1 g object will bob up and down. Until 2 g of water are moved, a 2 g object will float.
Regardless of their size, form, or type of construction material, heavy items sink and light objects float. An item must be entirely above the liquid's surface in order to be considered to be floating. There must be some trapped air in every thing that floats; this is the only explanation.
