Answer: its container

Explanation:

There are three states of matter:

Solid state : In this state, the molecules are arranged in regular and repeating pattern. The molecules are closely packed that means they are fixed and thus have fixed shape and volume.

For example : Copper

Liquid state : In this state, the molecules are present in random and irregular pattern. The molecules are closely packed but they can move from one place to another.  They have fixed volume and take the shape of the container.

For example : water

Gaseous state : In this state, the molecules are present in irregular pattern. The molecules are not closely packed and they can move freely from one place to another and spread out.  Thus they do not have any fixed shape and occupy the whole volume of the container.

For example : Helium gas

What is meant by the term neutral in relation to atoms?
Sonbull [250]

Answer:

it means positive and negative charges are  equal.

Explanation:

An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.

All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.

when a neutral atom loses a electron positive charge is created because  number of protons are positive charge becomes greater than negative charge.

X → X⁺ + e⁻

When a neutral atom accept  the electron negative charge is created because negative charge is become greater than positive charge.

X + e⁻ → X⁻

Which of the following pollutants could be reduced through proper maintenance and area ventilation to improve human health?
azamat

Answer:

Chimney soot

Explanation:

  • The periodicity of chimney used in homes is very highly harmful to human health.
  • If proper maintenance and cleanliness and ventilation are taken care of on such organic compounds, it can also control human health.
  • Carbon compounds form chimneys are highly harmful to human health if timber or coal-fired black chimney soot can be disposed of from time to time and with constant maintenance we can control pollution.

Enter the net ionic equation for the reaction of AgNO3(aq)
mixas84 [53]

Answer:

Explanation:

This is a typical double replacement or double decomposition reaction. In this kind of reaction, it involves the combination of ionic compounds which exchange their partners to form new compounds. Typical of these reaction is the formation of precipitates which are insoluble compounds.

The reaction equation is shown below:

 AgNO₃(_{aq} ) + K₂SO₄(_{aq} ) → 2KNO₃(_{aq} ) + AgSO₄(_{s} )

From the rule of solubility:

  • All trioxonitrate(v) salts are soluble
  • Salts of silver sulfates are slightly soluble. This will form the precipitate in the solution.

We can write the ionic equation as:

      Ag⁺(_{aq} ) + NO₃⁻(_{aq} ) + 2K⁺(_{aq} ) + SO₄²⁻(_{aq} ) → AgSO₄(_{s} ) + 2K⁺ + NO₃⁻(_{aq} )

The spectator ions or non-reactive ions are those ions that appears on both sides of the equation. These ions are the potassium and trioxonitrate ions. We cancel them out to give the net ionic equation of the reaction:

 Ag⁺(_{aq} ) + SO₄²⁻(_{aq} ) → AgSO₄(_{s} )
