Answer:- 0.45L

Solution:- From information, 0.25 L of acetic acid are present in 5 L of a solution. We could calculate the percentage of acetic acid in this solution using the formula:

percent by volume =(\frac{acid volume}{solution volume})100

Let's plug in the values in it:

percent by volume =(\frac{0.25}{5})100

= 5%

Now, it asks to calculate the volume of acetic acid present in 9 L solution with the same percentage. Let's use the same formula again and plug in the values in it:

5=(\frac{acid volume}{9})100

acid volume = \frac{5*9}{100}

acid volume = 0.45 L

So, 9 L of the solution must contain 0.45 L of acetic acid.

Write the net ionic equation:. . A solution of diamminesilver(I) chloride is treated with dilute nitric acid
zimovet [89]
<span> Ag(NH3)2Cl + 3HNO3 = AgNO3 +2NH4NO3 + HCl </span>
<span>or
 Ag(NH3)2Cl + HNO3 = Ag(NH3)2NO3 + HCl  this the complete balanced equation
now remove spectator ions to get net ionic equation
so 
</span>
<span> 2H+ + 2NO3- + [Ag(NH3)2]+ Cl- -> AgCl + 2NH4+ + 2NO3-  2NO3-  2H+  [Ag(NH3)2]+ + Cl- -> AgCl + 2NH4+

Electromagnetic waves will travel the SAME SPEED (speed of light) WITHIN a medium as it does WITHOUT a medium. Question options:
Marrrta [24]

Answer:

True

Explanation:

The speed that electromagnetic waves will travel within any medium is the same as those without a medium. The speed of electromagnetic wave is a constant and does not depend on the material of the medium.

  • Electromagnetic waves are waves that do not require a material medium for their propagation.
  • They are able to pass through vacuums and mediums with particles at constant speed.
  • It is mechanical waves whose speed is medium dependent.
  • Mechanical waves have varying speed based on the mediums they move through.
