This question is incomplete because you lack the options. But it can be answered based on my knowledge.

Two types of mixture could be: homogeneous and heterogeneous

A mixture is a term that refers to the combination of two or more components joined but not chemically combined. Mixtures can be classified as follows:

  • Homogeneous: Are characterized by having a uniform texture and appearance, their components are not distinguished.
  • For example: water + grapes = wine

Homogeneous mixtures can be:

  • Solutions: The mixtures formed are characterized by being formed with components that do not react chemically with each other, but that can modify their physical properties when they become part of the solution.
  • For example: coffee + milk = Coffee

There are also Colloids, a type of mixture formed by particles of one or more substances that are dispersed in another substance called a dispersing medium.

  • For example Gelatin powder + Water = Gelatin.

They are the intermediate mixtures between homogeneous and heterogeneous.

  • Heterogeneous: Are mixtures in which it is possible to observe their components due to the discontinuity with the naked eye.
  • For example Milk + cereal = Cereal

Why does it take so much heat and pressure to create helium and other elements?
ehidna [41]

Answer:

To break down the nucleus of an atom

Explanation:

Remember to change from one element to another, is necessary to add protons, neutrons and electrons,in most of the cases.

The take an electron from an atom you need certain energy, but they are in the outside part of the atom so is not as much energy as the one is necessary to take one neutron or proton from the inside part of an atom.

In this way, is a must to have a combination of pressure and heat to destabilize an atom and take some of this subatomic particles.

what is the volume of the air in a balloon that occupies 0.730 L at 28.0 c if the temperature is lowered to 0.00 C
svetoff [14.1K]

Answer:

The volume of the air is 0.662 L

Explanation:

Charles's Law is a gas law that relates the volume and temperature of a certain amount of gas at constant pressure. This law says that for a given sum of gas at a constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases because the temperature is directly related to the energy of the movement they have. the gas molecules. This is represented by the quotient that exists between volume and temperature will always have the same value:

\frac{V}{T}=k

If you have a certain volume of gas V1 that is at a temperature T1 at the beginning of the experiment and several the volume of gas to a new value V2, then the temperature will change to T2, and it will be true:

\frac{V1}{T1}=\frac{V2}{T2}

In this case:

  • V1= 0.730 L
  • T1= 28 °C= 301 °K (0°C= 273°K)
  • V2= ?
  • T2= 0°C= 273 °K

Replacing:

\frac{0.730 L}{301K}=\frac{V2}{273K}

Solving:

V2=273K*\frac{0.730L}{301K}

V2=0.662 L

<u><em>The volume of the air is 0.662 L</em></u>

Murrr4er [49]

A, radium-228. Alpha radiation is essentially just two protons and two neutrons leaving the atom, causing the atomic number to drop by two (since the protons left) and the mass number to drop by four (since two neutrons and protons left).
