A solid, a liquid, and a gas are each in separate covered jars. The substances are the same type but different states of matter.

Describe what will happen if the cover of each jar is removed. Explain how the difference in kinetic energy of the substances explains this result.

Explanation:

  • Gases are known to have more kinetic energy than liquids and solids bases on the kinetic molecular theory.
  • Due to the high energy of gases, their molecules are usually far apart and held together by  very weak attractive forces.
  • Liquids are more closely held by stronger attractive forces.
  • Solids are the most closely held by very strong attractive forces.
  • If one opens a jar containing the same matter but at these various states, it is expected that the gases will escape and diffuses to the environment.
  • The solids and liquids will remain in the container.
  • The kinetic energy of gases gives them enough energy to freely be randomized.

As the pendulum moves from point 2 to point 3, what happens to its mechanical energy?potential energy is converted to kinetic en
ahrayia [7]

Answer: Potential energy is converted to kinetic energy and back again.

Explanation:At points 1 and 3, the pendulum stops moving, and its mechanical energy is purely potential. At point 2, the pendulum is moving the fastest, and its mechanical energy is purely kinetic. Therefore, as the pendulum moves from point 1 to point 3, its potential energy is first converted to kinetic energy, then back to potential.

How many moles of glucose (C6H12O6) are in 1.5 liters of a 4.5 M C6H12O6 solution?
lisov135 [29]
Moles of glucose = Molarity x volume solution 
                              = 4.5 x 1.5
                              = 6.75 moles.

Hope this helps, have a great day ahead!

Describe the relationship between hydrogen oxygen and water
True [87]
Hydrogen is composed of H atom and oxygen is composed of O atom. For water, it is composed by both H and O atom. If you burn hydrogen in oxygen, you can get water. And if you electrolysis water, you can get hydrogen and oxygen.

Find the weight of HNO_3 present in 20ml, 0.30 N
yanalaym [24]

Answer:

mass of HNO₃ = 0.378 g

Explanation:

Normality = Molarity * number of equivalents

Molarity = Normality/number of equivalents

normality of HNO₃ = 0.30 N, Volume = 20 mL

HNO₃ ionizes in the following way:

HNO₃(aq) ----> H⁺ + NO₃⁻

Therefore, number of equivalents for HNO₃ is 1

molarity of HNO₃ = 0.30/1 =0.30 mol/dm³

Using the formula, molarity = number of moles/volume in liters

number of moles = molarity * volume

Number of moles of HNO₃ = 0.30 mol/dm³ * 20ml * 1 dm³ /1000 mL

number of moles = 0.006 moles

From the formula, mass = number of moles * molar mass

molar mass of HNO₃ = 63.0 g/mol

mass = 0.006 * 63

mass of HNO₃ = 0.378 g
