Boyle Law says “the pressure of fixed amount of ideal gas which is at constant temperature is
inversely proportional to its volume".<span>
P = 1/V
<span>Where, P is pressure of the ideal gas and V is volume of the ideal gas.</span>
<span>For two situations, this law can be added as;
P</span>₁V₁ = P₂V₂<span>
</span><span>14 lb/in² x V₁ = 70 lb/in² x 500 mL</span><span>
</span><span>V₁ =
2500 mL</span><span>
Hence, the needed volume of atmospheric air = 2500
mL
<span>Here, we made two </span>assumptions. They are,
1. The
atmospheric air acts as ideal gas.
2.
Temperature is a constant.
<span>We didn't convert the units to SI units since
converting volume and pressure are products of two numbers, they will cut off. </span></span></span>
Answer:
metals is the simplest form of crystalline solid
The answer is 7.
The equivalence point of a titration is when moles of titrant added becomes equal to the moles of sample analyte.
Calculate the pH at equivalence point for a strong acid and strong base reaction.
- The given acid is HCl which is a strong acid and the base NaOH is also a strong base.
- Calculate the moles of acid HCl:
Molarity of = 0.100 M
Volume of = 50 mL = 0.050 L

- At equivalence point, same moles of base are added and thus it results into complete neutralization. Thus, all the hydrogen ions of acid are neutralized by the hydroxide ions of the base forming only water and neutral salt.
- Thus, the pH at the equivalence point becomes 7 (neutral solution).

Take Lithium for an example. It would be able to fill up the 1s orbital, but then once it tried to fill up the 2s orbital, it would only have one electron left, since each s orbital can hold 2 electrons.
