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.

How many moles of calcium chloride are needed to react completely with 6.2 moles of silver nitrate
Harlamova29_29 [7]

Answer:

3.1 mol

Step-by-step explanation:

The balanced equation is

CaCl₂ + 2AgNO₃ ⟶ Ca(NO₃)₂ + 2AgCl

You want to convert moles of AgNO₃ to moles of CaCl₂.

The molar ratio is 2 mol AgNO₃:1 mol CaCl₂

Moles of CaCl₂ = 6.2 mol AgNO₃ × (1 mol CaCl₂/2 mol AgNO₃)

Moles of CaCl₂ = 3.1 mol CaCl₂

The reaction will require 3.1 mol of CaCl₂.

List two assumptions of the Kinetic Molecular Theory.
Phantasy [73]
These are 3 assumptions that i know for a fact. Hope this helped.

1.Gas particles are continuous, rapid, random motion. They therefore possess kinetic energy, which is energy of motion.

2.There are no forces of attraction between gas particles.

3.The temperature of a gas depends on the average kinetic energy of the particles of the gas.

The speed of light in a vacuum is 2.998 x 108 m/s. How long does it take for light to circumnavigate the Earth, which has a circ
Luba_88 [7]

Answer:

0.13 s

Explanation:

We'll begin by converting 24900 mile to metres (m). This can be obtained as follow:

1 mile = 1609.344 m

Therefore,

24900 mile = 24900 mile × 1609.344 m / 1 mile

24900 mile = 4.01×10⁷ m

Finally, we shall determine the time taken for light to circumnavigate the Earth, this can be obtained as follow:

Distance = 4.01×10⁷ m

Speed = 2.998×10⁸ m/s

Time =?

Speed = distance / time

2.998×10⁸ = 4.01×10⁷ / time

Cross multiply

2.998×10⁸ × time = 4.01×10⁷

Divide both side by 2.998×10⁸

Time = 4.01×10⁷ / 2.998×10⁸

Time = 0.13 s

Thus, it will take 0.13 s for light to circumnavigate the Earth.
