The balanced equation below shows the products that are formed when butane (C4H10) is combusted.
Nataly [62]

Answer:

2:8

Explanation:

The reaction equation is a given as:

         2C₄H₁₀   +    130₂   →    8CO₂     +     10H₂O  

From the reaction equation, the mole ratio is 2:8

Butane is C₄H₁₀

Carbon dioxide CO₂

From the reaction;

       2 moles of butane will produce 8 moles of carbon dioxide

Since volume and temperature are constant, this means that pressure and_____are____proportional. the sample with the largest____
IceJOKER [234]

Since volume and temperature are constant, this means that pressure and <u>number of moles</u> are <u>directly </u>proportional. the sample with the largest <u>number of moles</u> will have the <u>high </u>pressure.

Since, the ideal gas equation is also called ideal gas law. So,  according to ideal gas equations,

PV = nRT

  • P is pressure of the sample
  • T is temperature
  • V is volume
  • n is the number of  moles
  • R is universal gas constant

At constant volume and temperature the equation become ,

P ∝ nR

since, R is also constant. So, conclusion of the final equation is

P  ∝ n

The number of moles and pressure of the sample is directly proportion. So, on increasing number of moles in the sample , pressure of the sample also increases.

Alexandra [31]

Answer:

Hello friends

Explanation:

<h3>For a given principal quantum number for or n, the corresponding angular quantum number or is equivalent to a range between 0 and( n-1)</h3>

<h3>This means that the angular quantum number for a principal quantum number of 2 is equivalent to.</h3>

<h3>1 = 0 - > (n - 1) = 0 - > (2 - 1) = 0 - > 1</h3>

<h3>Hope it's helpfully. </h3>

Write einstein's equation that explains the energy from nuclear reactions. _________ use the caret symbol (^) to show an exponen
Katen [24]
I would say it should be Einstein's famous equation of e=mc^2 which means energy =mass x the speed of light squared. With this equation Einstein showed that energy comes from a mass travelling at the speed of light squared which is a fundamental equation to explain physical phenomena.
