An atom is the smallest part of an element
<h2>
Hello!</h2>
The answer is:
The new pressure will be equal to 6 atm.
<h2>
Why?</h2>
Since we know that the temperature is constant, we can use the Boyle's Law to solve the problem.
The Boyle's Law establishes that when the temperature is kept constant, the pressure and the volume will be proportional.
So, we have the equation:
We are given,
Substituting and isolating 
from the Boyle's Law, we have:
Hence, the new pressure will be equal to 6 atm.
Have a nice day!
Explanation:
You can test by putting sand in one cup and water in another. Then you put the thermometers in the cups. One you have done that you can use the heat lamp and put both cups under it for the same amount of time. After you do that and recorded your data you are done with the experiment.
Hope this helps :D
Answer:
Percent yield = 87.5%
Explanation:
Given data:
Number of moles of Fe(NO₃)₃ = 2.5 mol
Number of moles of Na₂CO₃ = 3.6 mol
Actual yield of NaNO₃ = 6.3 mol
Percent yield of NaNO₃ = ?
Solution:
Chemical equation:
2Fe(NO₃)₃ + 3Na₂CO₃ → Fe₂(CO₃)₃ + 6NaNO₃
now we will compare the moles of both reactant with NaNO₃.
Fe(NO₃)₃ : NaNO₃
2 : 6
2.5 : 6/2×2.5 = 7.5
Na₂CO₃ : NaNO₃
3 : 6
3.6 : 6/3×3.6 = 7.2
Theoretical yield of NaNO₃ is 7.2 mol.
Percent yield:
Percent yield = actual yield / theoretical yield ×100
Percent yield = 6.3 mol / 7.2mol ×100
Percent yield = 87.5%
Answer:
0.84kg of gatorade powder is needed.
Explanation:
From the question given above, we were told that the team manager mixes 0.6kg of gatorade powder with 5 gallons of water.
Now, to obtain the desired amount of the powder of gatorade needed for 7 gallons of water, we simply do the following:
If 0.6kg of gatorade powder required 5 gallons of water,
Then Xg of gatorade will require 7 gallons of water i.e
Xg of gatorade = (0.6 x 7)/5
Xg of gatorade = 0.84kg
Therefore, to maintain the same gatorade mixture, the team manager must mix 0.84kg of gatorade powder with the 7 gallons of water.
