Answer:

5 L

Explanation:

Given data

  • Initial pressure (P₁): 1 atm
  • Initial volume (V₁): 2.5 L
  • Final pressure (P₂): 0.50 atm
  • Final volume (V₂): ?

For a gas, there is an inverse relationship between the pressure and the volume. Mathematically, for an ideal gas that undergoes an isothermic change, this is expressed through Boyle's law.

P_1 \times V_1 = P_2 \times V_2\\V_2 = \frac{P_1 \times V_1}{P_2} = \frac{1atm \times 2.5L}{0.50atm}= 5 L

What is the empirical formula of C3H6N2
Evgen [1.6K]

Answer:

The empirical formula of the compound C₃H₆N₂ is C₃H₆N₂

Explanation:

The empirical formula of a compound is the formula of the compound given in the (smallest) whole number ratio of the elements of the compound

The empirical formula of S₂O₂ is SO

The empirical formula of C₃H₆O₃ is CH₂O

The given compound's molecular formula is C₃H₆N₂

The smallest whole number ratio of of the elements of the compound is 3:6:2, therefore, the empirical formula of the compound C₃H₆N₂ is C₃H₆N₂.

Which of the following electromagnetic waves are listed in the correct order from longest wavelength to shortest wavelength
Ghella [55]
Good afternoon,

Infrared light wavelengths = 1,000 nm - 750 nm

Visible light wavelengths = 750 nm - 400 nm

UV (Ultraviolet) light wavelengths = 400 nm - 10nm

So, the correct order is Infrared - Visible - Ultraviolet

I hope this has satisfied you, and if you need anymore help, feel free to ask.

Have a good afternoon!

Use the mean value off Keq to calculate the SCN- concentration in a solution whose initial Fe3+ concentration was 4.00x10^-2 M (
Colt1911 [192]
So the problem ask to justify that does the result of the calculation justify the original assumptions that all of the SCN is the form of FeNCS^2 and the best way to prove it is that both of them has a relative measurement percentage of 37.681%. I hope this helps

Bronze is an alloy. What is an alloy and why are they preferable at times?
Naddika [18.5K]
Alloys are mixtures of metals and other elements, which still keeps many characteristics of metal.

Alloys are sometimes desirable as they have some properties that the original metals don't, for example more flexibility or less fragility. Steel is such an alloy: it prevents movement of iron parts, making it stronger.
