Answer:
I think the answer is
Our solar system will always be part of the Milky Way.
Answer:
Explanation:
After the glorious appearance of Full Moon, the lunar shape starts to wane, meaning it gets smaller. It's visible later at night and into the early morning, and we see a steadily shrinking shape of the lunar surface that's being lit up.
Answer:
C . 24 L
Explanation:
Given data:
Initial volume of gas = 20.0 L
Initial pressure of gas = 660 mmHg
Final volume = ?
Final pressure = 550 mmHg
Solution:
The given problem will be solved through the Boly'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
660 mmHg × 20.0 L = 550 mmHg × V₂
V₂ = 13200 mmHg. L/ 550 mmHg
V₂ = 24 L
Al 3+ ions to S 2- ions in a neutral compound is 12 oxygen
Taking into account the definition of molarity, the molarity of a solution that contains 30 moles naoh in 0.80 liters of solution is 37.5 
.
<h3>Definition of molarity</h3>
Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.
The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:
Molarity is expressed in units .
<h3>This case</h3>
In this case, you have:
- number of moles= 30 moles
- volume= 0.80 L
Replacing in the definition of molarity:
Solving:
<u><em>Molarity= 37.5 </em></u><em />
Finally, the molarity of a solution that contains 30 moles naoh in 0.80 liters of solution is 37.5 .
