Therefore the pressure if the volume is increased to 4.12L the pressure is

P₂=0.636atm

<h3>What is helium?</h3>

Helium is a chemical element with the atomic number 2 and the letter He. It is a colourless, odourless, tasteless, non-toxic, inert, monatomic gas and the first member of the noble gas group in the periodic chartIt has the lowest melting and boiling points of all the elements.

<h3>What is the purpose of helium and is it a gas?</h3>

Since helium is a safe, non-flammable gas, it is frequently used to inflate balloons for festivities and parades. On the other hand, helium is a crucial component in several sectors, including high-tech manufacturing, medical technology, space exploration, and national security.

The second most prevalent element in the universe, helium, is scarce on Earth. It is the lightest noble gas, colourless, odourless, inert, and has a low boiling point. It is a byproduct of nuclear fusion and radioactive decay.

<h3>Briefing:</h3>

According to Boyle's Law:

P₁ V₁=P₂ V₂

P₁=1.61atm

V₁=2.26L

V₂=4.12L

P₂=(P₁ V₁)/V₂

P₂=((1.61atm)(2.26L))/4.12L

P₂=0.636atm

Boyle's Law states that the volume of a given quantity of gas at a constant temperature is inversely proportional to its pressure, so this makes sense. The pressure must decrease proportionally as the volume rises.

Pavel [41]

Answer:

<em>Protons: </em>

  • Positively charged particle
  • The number of these is the atomic number
  • All atoms of a given element have the same number of these

<em>Neutrons:  </em>

  • Neutral particles  
  • Isotopes of a given element differ in the number of these
  • The mass number is the number of these added to the number of protons

Explanation:

Protons (<em>positively charged</em>), neutrons (<em>neutral</em>) and electrons (negatively charged) are smaller than an atom and they are the main subatomic particles.  The nucleus of an atom is composed of protons and neutrons, and the electrons are in the periphery at unknown pathways.

The <em>Atomic number</em> (Z) indicates the number of protons (P^{+}) in the nucleus. Every atom of an element have the <em>same atomic number</em>, thus the <em>same number of protons</em>.

The <em>mass number </em>(A) is the sum of the <em>number of protons</em>  (P^{+}) <em>and neutrons</em> (N) that are present in the nucleus: <em>A= Z + N</em>

<em>Isotopes</em> are atoms of the <em>same element </em>which nucleus have the <em>same atomic number</em> (Z), and <em>different mass number (A)</em>, it means the <em>same number of protons</em> (P^{+}) and a <em>different number of neutrons</em> (N). For example, the oxygen in its natural state is a mixture of isotopes:

99.8% atoms with A= 16, Z=8, and N=8

0.037% atoms with A=17, Z=8, and N=9

0.204% atoms with A=18, Z=8, and N=10

Outline the difference between compounds and mixtures. State two examples of each.
alekssr [168]

Compounds are elements and its a pure substance with a gised composition.

Mixtures two or more subtances mixed to together.There are 2 type of mixtures.

Homegenous Mixtures (Solutions)-Two or more substances mixed but is uniform, you cant see the different mixtures.

Ex:Sugar mixed with water.The sugar dissolves and becomes one with the water.

Heterogeneous Mixtures-Two or more substances mixed but is not uniformed.You can see all the substances put into the mixture.

Ex:A salad, you can see whats all mixed in the sald and can pick it apart.

Give three reasons why fluid spills in water are more damaging than fluid spills on land
marta [7]

Answer:

1) Oil is less dense than water so when oil spills, it spreads across the entire water surface.

2) The oil spreads very quickly with lighter oils such as gasoline.

3) Wind, Currents, and Warm Temperatures will cause Oil to spread quicker.
