Answer:
V₂ = 12.5 mL
Explanation:
Given data:
Initial volume = 100.0 mL
Initial pressure = 50.0 KPa
Final volume = ?
Final pressure = 400.0 KPa
Solution:
The given problem will be solved through the Boyle's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
50.0 KPa × 100.0 mL = 400 KPa × V₂
V₂ = 5000 KPa.mL/ 400 KPa
V₂ = 12.5 mL
It seems that you have missed the necessary options for us to choose from, but anyway, here is the answer. The statement that is considered true about taste bud preferences would be this: The taste buds are located within the papillae of the tongue. Hope this answers your question.
Buoyancy is a force that acts on objects that are placed in a fluid is the correct answer
Let me know if I agit it!
Answer: D
Explanation:
because mold is a chemical reaction with with the air that's why the put a date cause the bread can only last for so long in till the chemical reaction.But D is is right because your body has to go though a chemical reaction in or to digest it and and break it down even more.So D would be the right answer cause that's where most of your chemical reaction happens when food is swallowed into the stoamch i hope i was able to explain it as much as i can
In this question, XB3(aq) is an ionic compound which will have the releasing of 3 B⁻ ions ions in water for every molecule of XB3 that dissolves.
XB3(s) --> X+(aq) + 3 B⁻(aq)
[B⁻] = 0.22 mol XB3/1L × 3 mol B⁻ / 1 mol XB3 = 0.66 M
The answer to this question is [B⁻] = 0.66 M
