Answer:
Explanation:
We shall apply gas law formula
P₁ V₁ / T₁ = P₂V₂ / T₂
.914 x 350 / ( 273 + 22.7 ) = 1 x 220 / T₂
1.0818 = 220 / T₂
T₂ = 203.36 K
= - 69.64 ⁰ C
a) the kinetic energy decreases as in a gas, the particles are widespread and move freely but in a liquid, their movement is more limited

The answer is:
<h2>
Why?</h2>
Since there is not information about the solute but only its mass, we need to assume that we are calculating the molar concentration of a solution or molarity. So, need to use the following formula:
Now, we know that the mass of the solute is equal 3.5 moles and the volume is equal to 1500 mL or 1.5L
Then, substituting into the equation, we have:
Have a nice day!
Answer:
The answer to your question is: letter C) 5730
Explanation:
Data
Originally Carbon - 14 254 g
Currently Carbon - 14 127 g
Half-life of Carbon -14 is when half of the original amount of Carbon disintegrates.
Then, if originally there were 254 and now there are 127, only one half life passed.
Half life of carbon -14 is 5730 years old.
