Answer:
Partial pressure of Ar = 4.7 atm
Explanation:
Total pressure of a mixture of gases = Sum of partial pressure of each gas
This mixture contains: O₂, He and Ar.
Total pressure = 15.3 atm
Total pressure = Partial pressure O₂ + Partial pressure of He + Partial pressure of Ar
15.3 atm = 7.4 atm + 3.2 atm + Partial pressure of Ar
Partial pressure of Ar = 15.3 atm - 7.4 atm - 3.2 atm
Partial pressure of Ar = 4.7 atm
Double I think am sooooo sorry if you get it wrong
<em>Answer:</em> 8 (feet)
<em>Explanation:</em>
24 inches = 2 feet
48 inches = 4 feet
12 inches = 1 foot
To find volume you do Base * Width * Height
2*4*1 = 8
Hope this helps!
Answer:
repelled
Explanation:
like charges repel one another
Answer:
The pH range, reaction rate, accuracy and solubility are affected by the temperature.
Explanation:
Hello,
Temperature is factor affecting how solutions behave, thus, it could modify the pH range (change in color values) for an indicator in the presence of a base or an acid, since the kinetics behind the change of color is modified maybe decreasing or increasing the aforesaid range. Next, temperature usually increases the reaction rate, that's why the change in color could become faster or out of the proper change range. Then, in titration we use temperature-sensitive glassware which could expand due to high temperatures and subsequently turning out into wrong measurements. Finally, solubility is affected by the temperature, since the molecules are allowed to interact more effectively, that's we must make sure that they're completely dissolved at room temperature while titrating.
Best regards.
