The answer would be the sun because of the intense radioactive fire coming from it, the heat and light travel through space and into earth's atmosphere. thats why your answer would be the sun.

Answer: A) the sun

Explanation: Nuclear energy can be defined as the energy which is present in the core of an atom. The core contains large amounts of energy present in the bonds that hold the nucleus together.

In sun nuclear fusion takes place where two or more atoms combine to form a larger atom, and a huge amount of energy is released in the process.

_1^2\textrm{H}+_1^3\textrm{H}\rightarrow _2^4\textrm{He}+ _0^1\textrm{n}+energy

Rocket engines and a coal burning power plant convert chemical energy stored in the bonds of chemicals to heat and light energy. In volcanoes heat energy of the magma is converted to light energy and the mechanical energy is converted to sound energy.

Magnesium has three stable isotopes. The most commonly occurring isotope, 24 Mg, has an isotopic mass of 23.985 u and makes up 7
aleksandr82 [10.1K]

Answer:

Average atomic mass = 24.3051 amu

Explanation:

Average Atomic Mass = (Mass of Isotope 1 x Fractional Abundance of Isotope 1) + (Mass of Isotope 2 x Fractional Abundance of Isotope 2) + ......

For 24 Mg

Mass = 23.985 amu

Fractional Abundance = 0.7899

Mass * Fractional Abundance = 18.9458

For 25 Mg

Mass = 24.986 amu

Fractional Abundance = 0.10

Mass * Fractional Abundance = 2.4986

For  26 Mg

Mass = 25.983

Fractional Abundance = 0.1101

Mass * Fractional Abundance = 2.8607

Average atomic mass = 24 Mg + 25 Mg + 26 Mg

Average atomic mass = 18.9458 + 2.4986 + 2.8607

Average atomic mass = 24.3051 amu

The vapor pressure of pure water at 250C is 23.77 torr. What is the vapor pressure of water above a solution that is 1.500 m glu
Olegator [25]

Answer:

Vapor pressure of water = 23.14torr

Explanation:

When you made a solution, vapor pressure decreases following Raoult's law:

P_{solution} = X_{solvent} P_{solvent}

<em>Where P is vapor pressure and X mole fraction</em>

As vapor pressure of water is 23.77torr we must find the mole fraction of water knowing the solution is 1.500m glucose (That is 1.500 moles of glucose per kg of water = 1000g of water).

1000g of H₂O are, in moles (Molar mass: 18.02g/mol):

1000g H₂O ₓ (1mole / 18.02g) = 55.5 moles of H₂O.

As we know now the solution contains 55.5 moles of water and 1.5 moles of glucose. Thus, mole fraction of water (Solvent) is:

X_{H_2O} = \frac{55.5molesH_2O}{55.5molesH_2O + 1.5 molesGlucose} = 0.9737

Replacing in Raoult's law, pressure of water above the solution is:

P_{solution} = X_{solvent} P_{solvent}

P_{solution} = 0.9737*23.77torr

<h3>Vapor pressure of water = 23.14torr</h3>
