Calculate the number of copper atoms in 2.45 mole of copper
nikdorinn [45]

Answer:

1.48×10²⁴ Cu atoms

Explanation:

For this question you need to use Avogadro's number 6.022×10²³atoms.

2.45 moles of Cu ×\frac{6.022x10x^{23} atoms }{1 mole}= 1.47539×10²⁴ atoms.

The moles cancel out so you are left with atoms.

Since there are 3 significant figures in the question there should be 3 significant figures in your answer, which is 1.48×10²⁴ Cu atoms.

Which phrase best defines radiant energy? (a)mechanical waves that require a medium to travel through
slava [35]

Answer:

I think is b

Explanation:

if im wrong, heres some information:

mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium.[1] While waves can move over long distances, the movement of the medium of transmission—the material—is limited. Therefore, the oscillating material does not move far from its initial equilibrium position. Mechanical waves transport energy. This energy propagates in the same direction as the wave. Any kind of wave (mechanical or electromagnetic) has a certain energy. Mechanical waves can be produced only in media which possess elasticity and inertia.

Richard and Brooke's teacher tells them to place 30 marbles in an 8-inch
Fynjy0 [20]

Answer:

The correct answer is - They gently shake the pan causing the marbles to move back and forth.

Explanation:

When water is heated the molecules present in its liquid state start to move and vibrate faster and allows the water to expand and increase in volume. If the heat is continuously applied to the water its molecules move even faster and escape in the form of molecules of vapor to the atmosphere.

To exhibit this phenomenon by the marble and pan, Richard and Brooke should gently shake the pan causing the marbles to move back and forth which shows faster vibration and movement of molecules.
