Mr. Thorton, the science teacher, was explaining the difference between kinetic and potential energy. He compared the difference

to a wind-up toy. He said, "kinetic energy is like a wind-up toy that is let go and is moving but potential energy is when the wind-up toy is wound up but not released yet." What misconception may come from this analogy?

A solid with a mass of Mgrams is melted by heating it. After a half-hour, the solid is
Lerok [7]

Answer:

equal to M

Explanation:

The mass of the fully melted mass and the initial solid will be the same. So, the mass of the melt is equal to M.

Mass is the amount of matter contained within a substance. Since only the phase changed and the amount of matter is still the same, the mass of the molten phase and the solid phase will remain the same.

We are correct to say that in the heating process no mass was destroyed or added in melting the solid.

A simple phase change that preserved the mass only occurred.

For the following reaction, 2 SO2(g) + O:(g) 2 SO,(g) the equilibrium constant, K, is 1.32 at 627°C. What is the equilibrium con
cupoosta [38]

Answer:

1.15  

Explanation:

2SO₂ + O₂ ⟶ 2SO₃; K =1.32

SO₂ + ½O₂ ⟶ SO₃;    K₁ = ?

When you divide an equation by 2, you take the square root of its equilibrium constant.

K₁ = √1.32 = 1.15

The equilibrium constant is 1.15.

When sedimentary rock sits for years and years will it build up more layers and. Make fossils
KengaRu [80]
Sedimentary rocks don't necessarily make fossils. Although when animals die on top of the rocks and are never moved, blown away, etc they can get trapped under the growing rock. Which is why fossils are often found in sedimentary rocks.

The ionization energies for removing successive electrons from sodium are 496 kJ/mol, 4562 kJ/mol,
ddd [48]

Answer:

D

Explanation:

The high jump of ionization energy indicates that we are trying to remove electron from noble gas configuration state.

The ionization energy data specifies that the Elements are from group 1 at period 3 or greater.

Removing the first electron require 496 kJ and the second ionization energy jump significantly due to the removal of electron from the noble gas configuration which is logical because electron try to maintain the especially stable state.
