Answer:

Explanation:

<u><em>1. low energy Boyle's . Law </em></u>

Boyle's law says that a constant temperature the volume of a mass of gas is inversely proportional to the pressure of that gas. This means that at a constant temperature when the pressure increases the volume decreases or vice versa.

All bodies possess internal energy, due in part to the kinetic energy of their particles. This energy is called thermal energy.  Temperature is directly related to the thermal energy of a body. As in this case the temperature is constant, the thermal energy will be constant.

<em><u>2. matter is continuously in motion solid</u></em>

 In the solid state the particles are bound by large forces than the distances joined at relatively small distances. The movement of the particles is limited to vibration, without being able to move.

<u><em>3. rapid, random motion Charles' Law</em></u>

Charles's law indicates that at constant pressure the volume of a given gaseous mass is directly proportional to its temperature. In other words, the volume of a gas at constant pressure decreases as the temperature drops.

As mentioned, the temperature is directly related to the thermal energy of a body, which is related to the movement of the particles. As in this case the temperature varies, the energy of the particles, and therefore the movement of them, will also vary.  As the temperature rises the movement of the particles will be faster. The gases move to any direction occupying all the available space, that is, their movement is random.

<u><em>4. relates pressure and volume Kinetic Molecular Theory</em></u>

<u><em> </em></u>The Kinetic Molecular Theory says that the pessure and volume are inversely proportional. This means that at the same temperature, the higher the pressure, the lower the volume. This is enunciated by Boyle's Law, shown previously.

<u><em>5. relates volume and temperature gas</em></u>

The volume, at a given pressure occupied by a gas, is directly proportional to its temperature. That is, at a higher temperature, greater volume if the pressure is constant. This is stated by the Law of Charles, shown above.

Not sure what you are trying to ask, but here is what I think you wanted.

In Boyle's Law the temperature is helped constant, so the kinetic energy of the molecules is a constant. The pressure and the volume are inversely related in Boyle's Law. In Kinetic theory pressure is created by the collision of particles. ( atoms or molecules) with each other and the container.

Gasses: Many substances at the pressures and temperatures available on Earth are gases, such as O2, N2, H2, Ar, Ne, CO2, etc.   • Gases have many different chemical properties, but their physical behaviors are remarkably similar. – O2 gas is a powerful oxidizing agent which supports combustion, H2 is extremely flammable, F2 is highly reactive, Ar is inert. – The gas laws in this chapter can be used to describe the physical properties of all of these chemically different gases. • It is easy (?) to interrelate pressure, volume, temperature, and amount of gases using the gas laws.  There are no comparable solid or liquid laws.

Matter: The kinetic theory of matter helps explain the different states of matter—solid, liquid, and gas. The particles in a solid, such as concrete, are not free to move around very much. They vibrate back and forth in the same position and are held tightly together by forces of attraction.

How many grams of hydrogen is produced from 12.5 G of MG reacting with hydrochloric acid in this balanced equation?
k0ka [10]

Answer:

1.03 grams of hydrogen is produced from 12.5 g of Mg reacting with hydrochloric acid.

Explanation:

The balanced reaction is:

Mg+ 2 HCl → MgCl₂ + H₂

By stoichiometry of the reaction, the following amounts of moles of each compound participate in the reaction:

  • Mg: 1 mole
  • HCl: 2 moles
  • MgCl₂: 1 mole
  • H₂: 1 mole

Being the molar mass of each compound:

  • Mg: 24.31 g/mole
  • HCl: 36.45 g/mole
  • MgCl₂: 95.21 g/mole
  • H₂: 2 g/mole

By reaction stoichiometry, the following mass amounts of each compound participate in the reaction:

  • Mg: 1 mole* 24.31 g/mole= 24.31 g
  • HCl: 2 moles* 36.45 g/mole= 72.9 g
  • MgCl₂: 1 mole* 95.21 g/mole= 95.21 g
  • H₂: 1 mole* 2 g/mole= 2 g

Then you can apply the following rule of three: if by stoichiometry 24.31 grams of Mg produces 2 grams of H₂, 12.5 grams of Mg produces how much mass of H₂?

mass of H_{2} =\frac{12.5 grams of Mg* 2 grams of H_{2}}{24.31 grams of Mg}

mass of H₂= 1.03 grams

<u><em>1.03 grams of hydrogen is produced from 12.5 g of Mg reacting with hydrochloric acid.</em></u>

calculate the standard potential arising from the reaction in which NADH is oxidized to NAD and the corresponding biological sta
melisa1 [442]

Answer:

-219.99kJ

Explanation:

The acronym '' NADH'' simply stands for what is known as coenzyme 1 with full meaning of Nicotinamide Adenine Dinucleotide Hydride. This substance is useful in the production of energy. The oxidation reaction of NADH causes it to produce NADP⁺ and the oxygen produces water when it is in the reduction process. The balanced equation for the oxidation reaction is given below as:

NADPH ---------------------------------------------------------------------> NADP⁺H⁺ + 2e⁻.

Also, the balanced equation for the reduction reaction is given below as:

\frac{1}{2} O₂ + 2H⁺ + 2e⁻ --------------------------------------------------------------> H₂O.

It can be shown from the above REDOX reaction that the total number of electrons getting transferred is 2.

The  Gibbs energy = -nFE. where n = 2, F = faraday's constant = 96485.3329 C and E = overall cell potential.

The overall cell potential = E[ reduction reaction] - E[oxidation reaction] = 0.82 - (- 0.32 ) = 1.14 V.

Hence, the Gibbs energy = - 2 × 96485.3329 × 1.14 = -219.99kJ

1 Clouds are formed when millions of drops of water become suspended in the air. Which
ioda

Answer:

C Condensation of water vapor

Explanation:

One of the components of the atmosphere is water vapour. Water vapour is always present in air.

This water vapour may combine with particles of dust and smoke and condense around them to form clouds.

As more water vapour condenses and coalesces, the clouds become thicker and precipitation eventually follows.

Which is larger Ca or Ca2+
kipiarov [429]

Answer:

Ca is larger than the Ca2+ because Ca2+ has a greater positive charge and electrons repel the nucleus.
